  • jQuery expanding menu

    - by Milen
    Hi everybody, i have this html code: <ul id="nav"> <li>Heading 1 <ul> <li>Sub page A</li> <li>Sub page B</li> <li>Sub page C</li> </ul> </li> <li>Heading 2 <ul> <li>Sub page D</li> <li>Sub page E</li> <li>Sub page F</li> </ul> </li> </ul> With this JS code: $(function(){ $('#nav>li>ul').hide(); $('#nav>li').mouseover(function(){ if ($('#nav ul:animated').size() == 0) { $heading = $(this); $expandedSiblings = $heading.siblings().find('ul:visible'); if ($expandedSiblings.size() > 0) { $expandedSiblings.slideUp(500, function(){ $heading.find('ul').slideDown(500); }); } else { $heading.find('ul').slideDown(1000); } } }); }) For now the code works this way: When click on Heading 1, menu is expanded. When click on Heading 2, heading2 submenu menu is expanded and heading 1 submenu is closed. I need to rework it to this: Submenus must be closed automatically on mouseout. Can somebody help me? Thanks in advance!

  • UIImagePickerController crashes on rapid scrolling, slower than photos app

    - by vvanhee
    Most of the time, my image picker works perfectly (iOS 4.2.1). However, if I scroll very rapidly up and down about 4-6 times through my camera roll of about 300 photos, I get a crash. This never happens with the "photos" app on the same iPhone 3Gs. Also, I'm noticing that the stock "photos" app scrolls much more smoothly than my image picker. Has anyone else noticed this behavior? I'd be interested if others could attempt this in their own apps and see if they crash. I don't think it's related to other objects hogging memory on my iPhone because it's a simple app, and this happens right after I start the app. It also doesn't seem to be related to messages sent to other released objects or overreleasing of other objects in viewdidunload, based on my crash logs and the fact that the simulator responds well to simulated memory warnings. I think it might be a bug in the internal implementation of the UIImagePickerController... This is how I start the picker. I've done this multiple ways (including setting a retain property for the UIImagePickerController in my header and releasing on dealloc). This seems to be the best way (crashes least): UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; picker.allowsEditing = YES; [self presentModalViewController:picker animated:YES]; [picker release]; This is the crashed thread (I get various exception types): Exception Type: SIGSEGV Exception Codes: SEGV_ACCERR at 0xfffffffff4faafa4 Crashed Thread: 8 ...

  • jquery ajaxstart ajaxstop show hide

    - by user1630583
    As usually seemingly simple things take days to resolve, maybe someone could point me to a solution but after 2 days I give up on the following problem; In html, in a form I have a button that is supposed to trigger loading of data through ajax call: <button type="" class="btn" onclick="getData(); return false;">Show Data</button> in javascript: $(document).ajaxStart(function() { $("#qloader").show(); }).ajaxStop(function() { $("#qloader").hide('slow'); });? and in html div with id qloader is defined with 100% width and height and spinner centered as the background, z-index above other: <div id="qloader" class="myLoader" >&nbsp;</div> Now, when page loads, ajax call is executed to get initial data, qloader div is brought up and it shows the spinner - animated, after ajax call finishes, qloader is hidden by ajaxStop. Next, when I click on a button (show data) to initiate another ajax call, ajaxStart is triggered, but it does not show qloader, it waits until ajaxStop is triggered and then in a blink of eye it shows qloader and hides it. I suspected that ajaxStart is not executed, so I put alert before $("#qloader").show(), then alert would be displayed and after that qloader WOULD be displayed BUT spinner animation would be suspended - no spinning, and after ajaxStop it would get hidden. Without alert in ajaxStart trigger, in subsequent ajax calls div is not shown until just before ajaxStop is triggered. It works fine for the first ajax call, but for subsequent ajax call triggered by click on form button it does not work. Any idea what is wrong with this setup?

  • ActionScript / AIR - One Button Limit (Exclusive Touch) For Mobile Devices?

    - by TheDarkIn1978
    two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time as any new button press would cancel all others. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific animated (tweened) reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

  • iphone how to determine and code according to base sdk version?

    - by Nareshkumar
    I have a code for UIImage picker photoImagePicker=[[UIImagePickerController alloc]init]; photoImagePicker.delegate=self; photoImagePicker.sourceType=UIImagePickerControllerSourceTypeCamera; photoImagePicker.mediaTypes=[UIImagePickerController availableMediaTypesForSourceType:photoImagePicker.sourceType]; [self presentModalViewController:photoImagePicker animated:YES]; photoImagePicker.showsCameraControls = YES; //Doesnot work on 3.0 photoImagePicker.navigationBarHidden = YES; photoImagePicker.toolbarHidden = YES; photoImagePicker.allowsEditing=YES; //Doesnt work on 3.0 Now everything works fine when the sdk is 3.1 or higher but when i put the os version as 3.0, the code starts showing errors. Turns out these methods were not present in 3.0 and so errors. I want to keep a mechanism which will enable these for higher versions(3.1) and at the same time work properly for 3.0 version. How do i do it? One solution i have thought of is to verify the version value and then put that code. But i am not sure how this is got. Any help will be appreciated.

  • CoreData is saving model without the save: method being called

    - by chris
    I have a list of items with a plus button in the navigation bar that opens up a modal window containing a table of the models attributes, that displays a form when the table items are clicked (pretty standard form style). For some reason if I click the plus button to open the form to create a new model, then immediately click the done button, the person model is saved. The action linked to the done button does nothing but call on a delegate method notifying the personListViewController to close the window. The apple docs do state that the model is not saved after calling the insertNewObjectForEntityName: ... Simply creating a managed object does not cause it to be saved to a persistent store. The managed object context acts as a scratchpad. I am at a lost to why this is happening, but every time I click the done button I have a new blank item in the original tableView. I am using SDK v3.1.3 // PersonListViewController - open modal window - (void)addPerson { // Load the new form PersonNewViewController *newController = [[PersonNewViewController alloc] init]; newController.modalFormDelegate = self; [self presentModalViewController:newController animated:YES]; [newController release]; } // PersonFormViewController - (void)viewDidLoad { [super viewDidLoad]; if ( person == nil ) { MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; self.person = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:appDelegate.managedObjectContext]; } ... UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; } - (IBAction) done { [self.modalFormDelegate didCancel]; } // delegate method in the original listViewController - (void) didCancel { [self dismissModalViewControllerAnimated:YES]; }

  • How to debug memory allocation issues?

    - by amitabh
    Hi I am writing an iPhone app that that is trying to create a second a view when the user clicks on an element in UITableView. The code looks like ReplyToViewController *reply = [[ReplyToViewController alloc] initWithNibName:@"ReplyTo" bundle:nil]; reply.delegate = self; Message *message = [resultData objectAtIndex:indexPath.row]; int dbid = [message.bizid intValue]; NSLog(@"dbid=%d",dbid); reply.currentMessage = message; reply.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:reply animated:YES]; The reply object gets created properly and the view is proper. Last line in above code segment calls some framework code which eventually calls the viewDidLoad method of the ReplyToViewController. Address of the reply object in the above code and the address of the object in viewDidLoad is not same. Any idea where this new object is coming from? How do I debug? I also added init method the following method in ReplyToViewController hoping that it will get called and I can find who is creating this new object. But it does not stop in this method. Any help will be greatly appreciated. - (id) init { /* first initialize the base class */ self = [super init]; return self; } // Following gets called from the 1st code segment. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; NSLog(currentMessage.text]; // THIS returns nil and the program fails later in the code. }

  • Method in RootViewController not Storing Array

    - by Antonio
    I have an array initialized in my RootViewController and a method that addsObjects to an array. I created a RootViewController object in my SecondViewController. The method runs (outputs a message) but it doesn't add anything to the array, and the array seems empty. Code is below, any suggestions?

  • iOS: display modal view over the top of a UIWebView

    - by Sly
    Is it possible to display a modal view over the top of a UIWebView? I have a UIViewController that loads a WebView. I then want to push a Modal View Controller over the top so that a modal view covers up the WebView temporarily... The WebView is working fine; here's how it's loaded in the View Controller: - (void)loadView { // Initialize webview and add as a subview to LandscapeController's view myWebView = [[[UIWebView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]] autorelease]; myWebView.scalesPageToFit = YES; myWebView.autoresizesSubviews = YES; myWebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight); myWebView.delegate = self; self.view = myWebView; } If I attempt to load a Modal View controller from within viewDidLoad, however, no modal view appears: - (void)viewDidLoad { [super viewDidLoad]; // Edit dcftable.html with updated figures NSMutableString *updated_html = [self _updateHTML:@"dcftable"]; // Load altered HTML file as an NSURL request [self.myWebView loadHTMLString:updated_html baseURL:nil]; // If user hasn't paid for dcftable, then invoke the covering modal view if (some_condition) { LandscapeCoverController *landscapeCoverController = [[[LandscapeCoverController alloc] init] autorelease ]; [self presentModalViewController:landscapeCoverController animated:YES]; } } I suspect that there's something that needs to be done with the UIWebView delegate to get it to receive the new modal view...but can't find any discussion or examples of this anywhere...again, the objective is to invoke a modal view that covers over the top of the WebView. Thanks for any thoughts in advance!

  • Dynamically creating subviews of similar type

  • What are the best software/website UI design you have even seen?

    - by Edwin
    What are the best UI design in terms of usability and esthetics you have even seen? I mean both desktop software (of all OS) and website. My list: Picasa 3 - the way it organizes photos. Find-and-highlight-as-you-type in google Chrome. Dynamic search hints when entering something in the search box in Gmail. I'm not a Mac OS X user, but I have seen in most windows on the top toolbar there are both the icons and texts shown for each function, as apposed to on Windows I have seen many programs (MS Office included) have many small toolbar icons which you can hardly understand what they do until you hover the mouse on it for a while to see the hints (if any). The ability to search an setting in Eclipse IDE. the way to make 3D models in Google Sketchup. the way to label an email in Gmail. What are you list? Well, I couldn't resist to list some annoying UI design I have experienced and remember at this moment. IE on Windows server, when you visit the new website, you have to click many times to get it added to the white list before you can start browsing, IIRC, it's not fixed in IE 8 when that last time I used it on Windows 2008. The default search behavior in the File Explorer on Windows xp, that animated thing... the dialog that shows up when you are trying to save a plain text CSV file in Excel after applied some formatting options which does not compatible with CSV.

  • jQuery slideDown + CSS Floats

    - by danilo
    I'm using a HTML Table with several rows. Every second row - containing details about the preceding row - is hidden using CSS. When clicking the first row, the second row gets showed using jQuery show(). This is quite nice, but I would prefer the slideDown-Effect. The problem is, inside the details row, there are two floating DIVs, one floating on the left, and one on the right. Now if i slideDown the previously hidden row, the contained DIVs behave strange and "jump around". See this animated gif to understand what I mean: http://ich-wars-nicht.ch/tmp/lunapic_127365879362365_.gif The markup: <tr class="row-vm"> <td>...</td> ... </tr> <tr class="row-details"> <td colspan="8"> <div class="vmdetail-left"> ... </div> <div class="vmdetail-right"> ... </div> </td> </tr> The CSS: .table-vmlist tr.row-details { display: none; } div.vmdetail-left { float: left; width: 50%; } div.vmdetail-right { float: right; width: 50%; } And the jQuery code: if ($(this).next().css('display') == 'none') { // Show details //$(this).next().show(); $(this).next().slideDown(); } else { // Hide details //$(this).next().hide(); $(this).next().slideUp(); } Is there a way to fix this behavior, and to implement a nice slideDown-effect?

  • How can I use a meter-style progress bar?

    - by Yadyn
    In Vista/7, the Windows Explorer shell window makes use of a special kind of static progress bar to display hard drive space. With default styles, this bar is blue colored and non-animated. It also turns red colored when it gets close to being full (low disk space). Using messaging, I can tell the Windows Forms ProgressBar control to update its state to Paused and Error (yellow and red colored, respectively), which works fine, but these are still specific to progress. In the Windows User Experience Guidelines, it specifically points out this "meter" variant of the Progress Bar: This pattern isn't a progress bar, but it is implemented using the progress bar control. Meters have a distinct look to differentiate them from true progress bars. They say it "is implemented using the progress bar control", so... how? What message could I send to the control to have it behave this way? I've seen that you can send messages for setting the bar color, but the documentation says these calls are ignored when visual styles are enabled. Nothing else in the Windows API documentation for raw ProgressBar controls seemed to suggest a way to do this. Am I just stuck making a custom drawn bar? I'd really like to utilize the OS whenever possible so that the application will appear consistent throughout different OS versions. I realize that pre-Vista versions probably won't support this, though. I'm looking for a Windows Forms solution, but I wonder if it is even exposed at all via Win32 API.

  • Refreshing a MKMapView when the user location is updated or using default values

    - by koichirose
    I'm trying to refresh my map view and load new data from the server when the device acquires the user location. Here's what I'm doing: - (void)viewDidLoad { CGRect bounds = self.view.bounds; mapView = [[MKMapView alloc] initWithFrame:bounds]; mapView.showsUserLocation=YES; mapView.delegate=self; [self.view insertSubview:mapView atIndex:0]; [self refreshMap]; } - (void)mapView:(MKMapView *)theMapView didUpdateUserLocation:(MKUserLocation *)userLocation { //this is to avoid frequent updates, I just need one position and don't need to continuously track the user's location if (userLocation.location.horizontalAccuracy > self.myUserLocation.location.horizontalAccuracy) { self.myUserLocation = userLocation; CLLocationCoordinate2D centerCoord = { userLocation.location.coordinate.latitude, userLocation.location.coordinate.longitude }; [theMapView setCenterCoordinate:centerCoord zoomLevel:10 animated:YES]; [self refreshMap]; } } - (void)refreshMap { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; [self.mapView removeAnnotations:self.mapView.annotations]; //default position NSString *lat = @"45.464161"; NSString *lon = @"9.190336"; if (self.myUserLocation != nil) { lat = [[NSNumber numberWithDouble:myUserLocation.coordinate.latitude] stringValue]; lon = [[NSNumber numberWithDouble:myUserLocation.coordinate.longitude] stringValue]; } NSString *url = [[NSString alloc] initWithFormat:@"http://myserver/geo_search.json?lat=%@&lon=%@", lat, lon]; NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; [url release]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; } I also have a - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data, to create and add the annotations. Here's what happens: sometimes I get the location after a while, so I already loaded data close to the default location. Then I get the location and it should remove the old annotations and add the new ones, instead I keep seeing the old annotations and the new ones are added anyway (let's say I receive 10 annotations each time, so it means that I have 20 on my map when I should have 10). What am I doing wrong?

  • Scroll view to bottom while keyboard is hiding

    - by Manu
    Hi! I'm using a scroll view to move my view and show certain text fields (that otherwise would be hidden) when the keyboard shows. I basically resize the scroll view to make room for the keyboard, and then scroll up the view smoothly with "scrollRectToVisible", which works perfectly. After that, I can scroll and edit the rest of the text fields without lowering the keyboard, which is what I intend. The problem comes when I want to hide the keyboard again. I have been able to lower the keyboard and scroll down the view to its original position without a problem, but I have been unable to make that transition smooth. At the moment I use the following: - (void)keyboardWillHide: (NSNotification *)notif { CGRect topRect = CGRectMake(0, 0, 1, 1); [scrollview scrollRectToVisible:topRect animated:YES]; scrollview.frame = CGRectMake(0, 0, scrollviewWidth, scrollviewHeight); } I create a CGRect at the top, which I then move into view with "scrollRectToVisible". That works fine and commences the scrolling right when the keyboard is hiding (I use "keyboardWillHide" and not "keyboardDidHide" because the scroll view frame is still missing its lower part). The problem comes when I resize the scroll view frame back to its original dimensions (which I need to do), because then the scrolling is interrupted and the view drops to the bottom suddenly (as there is nothing else to scroll). This causes a glitch, which is why I cannot complete the transition smoothly. Any ideas on how could I lower the keyboard while scrolling the view down smoothly? Should I be scrolling up a bigger view, instead of resizing it? That way I would not have to restore the scroll view frame dimensions when lowering the keyboard, or would I? Thanks very much in advance!

  • Knowing which annotation is selected and accessing properties of it.

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • IE10 - Progress bar animation issue

    - by user3723885
    I'm trying to incorporate some animated progress bars but I'm having trouble getting them to animate in IE10. I believe the problem is due to the keyframes being inside the media query but have not been able to get it working. Thanks for your help. HTML: <td><div style="width:150px;height:15px;border:1px solid black"> <div class="meter"> <span style="width:85%;"><span class="progress"></span></span> </div> </div></td></tr> CSS: .progress { background-color: #325C74; -webkit-animation: progressBar 3s ease-in-out; -webkit-animation-fill-mode:both; -moz-animation: progressBar 3s ease-in-out; -moz-animation-fill-mode:both; } @-webkit-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } } @-moz-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } }

  • Navigation Controller not Pushing/Popping View Controllers

    - by senfo
    I'm working on a view-based iPhone app that has the following flow: search - (list | map) - details To accomplish the transitions between views, I have a UINavigationController, with the search view controller being the root. After a user performs a search, I transition to a view with a segmented control, which acts as a tab to switch between the list and map functionality (per a suggestion from a related question I had). This view contains a UIViewController, which allows me to switch between the list/map view when a user taps the segmented control. I'm fine up until this point. As you can see from the above mentioned flow, I would like to provide the ability to transition into a details view. Each row of my table in the list view contains a details disclosure button for allowing the user to drill down into a details view. The problem is, when I try to push the details view onto the navigation stack, nothing happens. Below is the delegate method (from my list view controller) to handle the details disclosure button being tapped. I've set up break points, so I know the code is running. The navigation controller simply doesn't want to push the detailsController onto the stack (my guess is that I don't have a pointer to the correct UINavigationController). - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { if (detailController == nil) { detailController = [[DetailsViewController alloc] init]; } [self.navigationController pushViewController:detailController animated:YES]; } Assuming I was probably missing a pointer to the navigation controller, I exposed a UINavigation property on my list and map views (navigationController is readonly) and initialized them with a pointer to the navigation controller from my SwitchViewController (the view responsible for switching between list/map views when a user changes the value of the segmented control). Unfortunately, this did not solve the problem. Am I on the right track? If so, how do I see to it that my view has a pointer to the correct navigation controller? Should I add a delegate, which allows me to call a function in the SwitchViewController that transitions into the details view (this seems messy)?

  • Defined outlets, connected them, they all returns (null)

    - by Tom
    Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView: EDIT: That is how I call the view: DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; dvController.workflow_id = parent_id; Etape *etape = [[Etape alloc] init]; dvController.etapes = [etape getEtapes:parent_id]; [etape release]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release];

  • how do I get the program to Know which annotation is selected and be able to access properties of it

    - by kevin Mendoza
    So far my program can display a database of custom annotation views. Eventually I want my program to be able to display extra information after a button on the annotation bubble is clicked. Each element in the database has a unique entry Number, so I thought it would be a good idea to add this entry number as a property of the custom annotation. The problem I am having is that after the button is clicked and the program switches to a new view I am unable to retrieve the entry number of the annotation I selected. Below is the code that assigns the entry Number property to the annotation: for (id mine in mines) { workingCoordinate.latitude = [[mine latitudeInitial] doubleValue]; workingCoordinate.longitude = [[mine longitudeInitial] doubleValue]; iProspectAnnotation *tempMine = [[iProspectAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:[mine mineName]]; [tempMine setAnnotationEntryNumber:[mine entryNumber]]; } [mines dealloc]; When the button on an annotation is selected, this is the code that initializes the new view: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { mineInformationController *controller = [[mineInformationController alloc] initWithNibName:@"mineInformationController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [self presentModalViewController:controller animated:YES]; [controller release]; } and lastly is my attempt at retrieving the entryNumber property from the new view so that I can compare it to the mines database and retrieve more information on the array element. iProspectFresno_LiteAppDelegate *appDelegate = (iProspectFresno_LiteAppDelegate *)[[UIApplication sharedApplication] delegate]; NSMutableArray* mines = [[NSMutableArray alloc] initWithArray:(NSMutableArray *)appDelegate.mines]; for(id mine in mines) { if ([[mine entryNumber] isEqualToNumber: /*the entry Number of the selected annotation*/]) { /* display the information in the mine object */ } } So how do I access this entry number property in this new view controller?

  • Is it okay for multiple objects to retain the same object in Objective-C/Cocoa?

    - by Andrew Arrow
    Say I have a tableview class that lists 100 Foo objects. It has: @property (nonatomic, retain) NSMutableArray* fooList; and I fill it up with Foos like: self.fooList = [NSMutableArray array]; while (something) { Foo* foo = [[Foo alloc] init]; [fooList addObject:foo]; [foo release]; } First question: because the NSMutableArray is marked as retain, that means all the objects inside it are retained too? Am I correctly adding the foo and releasing the local copy after it's been added to the array? Or am I missing a retain call? Then if the user selects one specific row in the table and I want to display a detail Foo view I call: FooView* localView = [[FooView alloc] initWithFoo:[self.fooList objectAtIndex:indexPath.row]]; [self.navigationController pushViewController:localView animated:YES]; [localView release]; Now the FooView class has: @property (nonatomic, retain) Foo* theFoo; so now BOTH the array is holding on to that Foo as well as the FooView. But that seems okay right? When the user hits the back button dealloc will be called on FooView and [theFoo release] will be called. Then another back button is hit and dealloc is called on the tableview class and [fooList release] is called. You might argue that the FooView class should have: @property (nonatomic, assign) Foo* theFoo; vs. retain. But sometimes the FooView class is called with a Foo that's not also in an array. So I wanted to make sure it was okay to have two objects holding on to the same other object.

  • [C#] Dynamic user-interface, WPF or not?

    - by pieter.lowie
    Hi, I'm currently working at a application that helps people understand how to do there job. You can see it as a personal coach that guides them trough all the steps they need to do that no normal person could keep remembering. In my previous application we had the ability to show the user up to 4 pictures (what proves to be more then enough). The application would load the data and see how many pictures where in every instruction and then sort out the picture in the best fitting way without messing up the scale and resolution of the pictures. This all was done with GDI+ and worked very well. Ofc, change is something that always happens, my bosses came up with some great ideas. So they want to be able to see movies on the screen, animated gif's, 3D models that can rotate or animate. So I think we had pushed GDI+ to it's limits and it's time to look for something different. I have heard and readed about WPF but have no experience with it. Is it even possible to do all what I ask in WPF? And what about the old picture-merging thing I wrote, can we also get it done in wpf? I tried to make some things working but I didn't went as smooth as I hoped. I'm also concerned about the fact that the interface needs to be dynamic, the one moment it should be showing picture with some text above it, the other moment it should be showing another text with a video under it. I would love to hear some opinions here and if you got some other suggestions I should look into pls tell me. Thnx in advance PS: If WPF is the choice, should I convince my boss to change to .net 4.0?

  • Unable to dismiss MFMailComposeViewController, delegate not called

    - by Rod
    HI, I am calling MFMailComposeViewController from UITableViewController. Problem is, delegate method mailComposeController:(MFMailComposeViewController)controllerdidFinishWithResult* is never called when I select Cancel or Send button in Mail compose window. Here is the table view class: @implementation DetailsTableViewController - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section==0 && indexPath.row==4){ //SEND MAIL MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init]; controller.mailComposeDelegate = self; if ([MFMailComposeViewController canSendMail]) { [controller setSubject:[NSString stringWithFormat:@"Ref %@",[item objectForKey:@"reference"]]]; [controller setMessageBody:@" " isHTML:NO]; [controller setToRecipients:[NSArray arrayWithObject:[item objectForKey:@"email"]]]; [self presentModalViewController:controller animated:YES]; } [controller release]; } } - (void)mailComposeController:(MFMailComposeViewController*)controllerdidFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { // NEVER REACHES THIS PLACE [self dismissModalViewControllerAnimated:YES]; NSLog (@"mail finished"); } The application don't crash. After Cancel or Send button is presses Compose Window stays on the screen with buttons disabled. I can exit application pressing Home key. I am able to open other Modal Views form TableView but not MailCompose.
