  • Background problem on UITableView

    - by f0rz
    Hi ! I have come to a problem, wich I have no idea how to solve. Can anyone think outside the box and point me to right directions? I would be very thankfull ! The problem. I have a UITableView containing a first row wich is always the same (a empty row with repeating background) Next rows are bounch of dynamic data rows. I have set the yellow background on my UITableView in IBuilder, My cells (except first row) have white background with code: UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ]; backgroundView.backgroundColor = [UIColor colorWithRed: 0.96078431372549 green: 0.96078431372549 blue: 0.96078431372549 alpha: 1.0]; cell.backgroundView = backgroundView; for ( UIView* view in cell.contentView.subviews ) { view.backgroundColor = [ UIColor clearColor ]; } The example yellow background, I only want to be showed at the top. As u see img example below. The thing is I dont want to have yellow background under the last datarow, I want to contain same white color I have on the cells. This should be white as the cells. Not yellow. Thank u for your time. Regards

  • Redirecting input to another view

    - by Jon
    My application is working fine on the normal iPad display, but I also need to output to VGA out. When I do this, I need to add the view to the external screen's window which seems to mean that I can't use it to accept input from the iPad screen. I want to redirect input from the iPad's window to the window displaying on the external screen. As far as I can tell there's no standard method of doing this. I've tried overriding hitTest on the iPad's window view to send it to the window on the external display, but the coordinates seem to get messed up in the process which makes it nigh unusable. I've also tried subclassing the iPad's UIWindow and catching events in sendEvent, then trying to send them to the external window, but this doesn't seem to work at all. Any help would be appreciated, I'm happy to post any code you would like to see. Thanks, Jon

  • UIImageView subclass with CGRectIntersectsRect - help!

    - by Flafla2
    The title of this question should be pretty self explanatory. I am making an app that involves multiple UIImageViews that serve the same purpose. They are merely different sizes. Anyway, I decided that the best solution was to make UIImageView subclasses, link the subcalsses in IB, and work from there. My code should explain this better - #define kPausedStatePaused 1 #define kPausedStatePlay 2 #import "Game.h" #import "ScoreSystem.h" @interface Doctor : UIImageView { } @end @interface Ground : UIImageView { } @end @interface Wall : UIImageView { } @end @interface Electric_Wire : UIImageView { } @end @implementation Game /* // The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { // Custom initialization } return self; } */ /* // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; } */ - (IBAction)pause { UIAlertView *pause = [[UIAlertView alloc] initWithTitle:@"Pause" message:nil delegate:self cancelButtonTitle:@"Quit" otherButtonTitles:@"Play", nil]; [pause show]; [pause release]; pauseint = kPausedStatePaused; } - (void)viewDidAppear { pauseint = kPausedStatePlay; } - (void)loop { Doctor *doctorview; Ground *groundview; if (CGRectIntersectsRect(doctorview, groundview)) { } } - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if ([alertView.title isEqual:@"Pause"]) { if(buttonIndex == 0) [self dismissModalViewControllerAnimated:YES]; pauseint = kPausedStatePlay; } } // Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end Unsurprisingly, Xcode gave me an "incompatible type for CGRectIntersectsRect" error.

  • Issues adding search to iPhone app

    - by Graeme
    Hi, Basically I'm trying to add a search function to my iPhone app, but I'm not having much luck at the moment. I've downloaded the Apple provided Table Search app, and have copied across the code to mine. It builds OK, but here's the problem. Unlike the Apple example, all my data is stored in an array, that is accessed by calling [ciParser.currentArray]. Any ideas on how to change the code to suit my needs? I'm getting an error "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)'" whenever I click on the search bar and the app exits. Below is the code in particular that the debugger highlights as being troublesome. Apparently this error means the database trying to be searched is empty, but I could be wrong. FYI my app downloads and parsers an RSS feed using a class which is referenced by ciParser - which in turn stores the downloaded content in an array that I need to search. // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } /* If the requesting table view is the search display controller's table view, configure the cell using the filtered content, otherwise use the main list. */ CurrentItem * nextCurrentItem=[ciParser.currentArray objectAtIndex:indexPath.row]; if (tableView == self.searchDisplayController.searchResultsTableView) { (Code which debugger points to as being wrong) nextCurrentItem = [self.filteredListContent objectAtIndex:indexPath.row]; } else { nextCurrentItem = [ciParser.currentArray objectAtIndex:indexPath.row]; } NSString*settingValue = [[NSUserDefaults standardUserDefaults]stringForKey:@"state"]; if ([settingValue isEqualToString:@"New South Wales"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Western Australia"]) { cell.textLabel.text=@"The FESA does not provide any Current Incident reports."; } else if ([settingValue isEqualToString:@"Victoria"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"South Australia"]) { cell.textLabel.text=nextCurrentItem.title; } else if ([settingValue isEqualToString:@"Tasmania"]) { cell.textLabel.text=nextCurrentItem.title; } // Set up the cell... [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; return cell; }

  • can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

    - by Wesley
    So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

  • UIAlertViewDelegate clickedButtonAtIndex: usefulness?

    - by Ed Marty
    The UIAlertViewDelegate protocol defines two methods, alertView:clickedButtonAtIndex: and alertView:didDismissWithButtonIndex:, which seem to me to be identical in usefulness. Why is there a clickedButtonAtIndex and a didDismissButtonWithIndex when they both do the same thing? I realize there is also a willDismissButtonWithIndex that happens before the alert view is dismissed, but is there any reason to use clickedButtonAtIndex instead of didDismissButtonWithIndex?

  • Keyboard blocking my view

    - by John Smith
    I have a UIView with another UIView inside it. On the inside UIView there is a textbox which I want to fill in. When I try to fill it in the keyboard blocks my view: The UIViewController has the following containerView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds]; self.view=containerView; //The apropriate releases etc are further on... When I touch it, the keyboard comes up as expected, but blocks the textbox I'm trying to fill in. How can I force the view to slide up? The front view OptionsFront * fv = [[OptionsFront alloc] initWithFrame:[UIScreen mainScreen].bounds]; [containerView addSubview:frontView]; In the front view is a subview CGRect bounds = CGRectMake(0.0f, 210.0f, 280.0f, 130.0f); sv = [[UIView alloc] initWithFrame:bounds]; [self addSubview:sv]; //added to frontView In sv is a textbox near the botton: rect = CGRectMake(70.0f, 20.0f, 100.0f, 27.0f); cf = [self createTextField_Rounded:rect holder:@"+ve"]; [sv addSubview:cf]; So cf happens to be near the bottom of the page. I expected that when I select it, the whole display would move up, but the keyboard just moves up and blocks it. What can I do? Appendix: - (UITextField *)createTextField_Rounded:(CGRect) frame holder:(NSString *) ph { UITextField *returnTextField = [[UITextField alloc] initWithFrame:frame]; returnTextField.borderStyle = UITextBorderStyleRoundedRect; returnTextField.textColor = [UIColor blackColor]; returnTextField.font = [UIFont systemFontOfSize:17.0]; returnTextField.delegate = self; returnTextField.keyboardType = UIKeyboardTypeNumbersAndPunctuation; returnTextField.returnKeyType = UIReturnKeyDone; returnTextField.clearButtonMode = UITextFieldViewModeWhileEditing; return returnTextField; }

  • MPMediaPickerController, MPMediaItems, and NSData

    - by ckrames1234
    I was wondering if Apple allowed you to access the MPMediaItem's raw data as an NSData object. If you can, thats great and I would like to know how. If you cannot, then Apple is way too over-protective, and my app that i started is utterly useless. Also if you cannot, Is there any hacky workarounds? I don't care if Apple doesn't accept my app as it would still be cool if me and my friends all had it. Thanks, Conrad

  • Advanced Localization with Omission of Arguments in Xcode

    - by coneybeare
    I have this formatted string that I am having a translator work on. ENGLISH "Check out the %1$@ %2$@ in %3$@: %4$@" = "Check out the %1$@ %2$@ in %3$@: %4$@" GERMAN TRANSLATION "Check out the %1$@ %2$@ in %3$@: %4$@" = "Hör Dir mal %2$@ in %3$@ an: %4$@"; These are passed to a [NSString stringWithFormat:] call: ////////////////////////////////////// // Share Over Twitter NSString *frmt = NSLocalizedString(@"Check out the %1$@ %2$@ in %3$@: %4$@", @"The default tweet for sharing sounds. Use %1$@ for where the sound type (Sound, mix, playlist) will be, %2$@ for where the audio name will be, %3$@ for the app name, and %3$@ for where the sound link will be."); NSString *urlString = [NSString stringWithFormat:@"sounds/%@", SoundSoundID(audio)]; NSString *url = ([audio audioType] == UAAudioTypeSound ? UrlFor(urlString) : APP_SHORTLINK); NSString *msg = [NSString stringWithFormat: frmt, [[Audio titleForAudioType:[audio audioType]] lowercaseString], [NSString stringWithFormat:@"\"%@\"", AudioName(audio)], APP_NAME, url]; NSString *applink = [NSString stringWithFormat:@" %@", APP_SHORTLINK]; if (msg.length <= (140 - applink.length)) { msg = [msg stringByAppendingString:applink]; } returnString = msg; With the desired and actual outcome of: ENGLISH desired: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" actual: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" GERMAN desired: "Hör Dir mal "This Sound Name" in My App Name an: link_to_sound link_to_app" actual: "Hör Dir mal sound in "This Sound Name" an: My App Name link_to_app" THE PROBLEM The problem is that I was under the assumption that by using numbered variable in the NSLocalizedString, I could do things like this, where the %1$@ variable is completely omitted. If you notice, the German translation of the format string does not use the first argument (%1$@) at all but it ("sound") still appears in the output string. What am I doing wrong?

  • If array is thread safe, what the issue with this function?

    - by Ajay Sharma
    I am totally lost with the things that is happening with my code.It make me to think & get clear with Array's thread Safe concept. Is NSMutableArray OR NSMutableDictionary Thread Safe ? While my code is under execution, the values for the MainArray get's changes although, that has been added to Array. Please try to execute this code, onyour system its very much easy.I am not able to get out of this Trap. It is the function where it is returning Array. What I am Looking to do is : -(Array) (Main Array) --(Dictionary) with Key Value (Multiple Dictionary in Main Array) ----- Above dictionary has 9 Arrays in it. This is the structure I am developing for Array.But even before #define TILE_ROWS 3 #define TILE_COLUMNS 3 #define TILE_COUNT (TILE_ROWS * TILE_COLUMNS) -(NSArray *)FillDataInArray:(int)counter { NSMutableArray *temprecord = [[NSMutableArray alloc] init]; for(int i = 0; i <counter;i++) { if([temprecord count]<=TILE_COUNT) { NSMutableDictionary *d1 = [[NSMutableDictionary alloc]init]; [d1 setValue:[NSString stringWithFormat:@"%d/2011",i+1] forKey:@"serial_data"]; [d1 setValue:@"Friday 13 Sep 12:00 AM" forKey:@"date_data"]; [d1 setValue:@"Description Details " forKey:@"details_data"]; [d1 setValue:@"Subject Line" forKey:@"subject_data"]; [temprecord addObject:d1]; d1= nil; [d1 release]; if([temprecord count]==TILE_COUNT) { NSMutableDictionary *holderKey = [[NSMutableDictionary alloc]initWithObjectsAndKeys:temprecord,[NSString stringWithFormat:@"%d",[casesListArray count]+1],nil]; [self.casesListArray addObject:holderKey]; [holderKey release]; holderKey =nil; [temprecord removeAllObjects]; } } else { [temprecord removeAllObjects]; NSMutableDictionary *d1 = [[NSMutableDictionary alloc]init]; [d1 setValue:[NSString stringWithFormat:@"%d/2011",i+1] forKey:@"serial_data"]; [d1 setValue:@"Friday 13 Sep 12:00 AM" forKey:@"date_data"]; [d1 setValue:@"Description Details " forKey:@"details_data"]; [d1 setValue:@"Subject Line" forKey:@"subject_data"]; [temprecord addObject:d1]; d1= nil; [d1 release]; } } return temprecord; [temprecord release]; } What is the problem with this Code ? Every time there are 9 records in Array, it just replaces the whole Array value instead of just for specific key Value.

  • uniimageview not updating after views tranistion

    - by Fabio Ricci
    Hi I have one main view where I display an image, in the method viewDidLoad: ballRect = CGRectMake(posBallX, 144, 32.0f, 32.0f); theBall = [[UIImageView alloc] initWithFrame:ballRect]; [theBall setImage:[UIImage imageNamed:@"ball.png"]]; [self.view addSubview:theBall]; [laPalla release]; Obviously, the value of posBallX is defined and then update via a custom method call many times in the same class. theBall.frame = CGRectMake(posBallX, 144, 32, 32); Everything works, but when I go to another view with [self presentModalViewController:viewTwo animated:YES]; and come back with [self presentModalViewController:viewOne animated:YES]; the image is displayed correctly after the method viewDidLoad is called (I retrieve the values with NSUserDefaults) but no more in the second method. In the NSLog I can even see the new posBallX updating correctly, but the Image is simply no more shown... The same happens with a Label as well, which should print the value of posBallX. So, things are just not working if I come back to the viewOne from the viewTwo... Any idea??????? Thanks so much!

  • How to recognize the touch of a non regular sprite image ?

    - by srikanth rongali
    I have a sprite and if it is touched the touch should be recognized. I used the coordinates to do so. I took the coordinates (min x, min y, max x , max y)of the sprite image. But The sprite image is not a rectangular shape. So, even if I touch the coordinates outside the sprite and inside the rectangular bounds the sprite is recognized. But for my application I need only the sprite to be recognized. So, I have to take only the coordinates of the sprite, but it is not regular shape. I am using CCSprite in my program. So, what can I do to for only the sprite to be selected ? Which classes should use for this? Thank You.

  • Google Docs iphone library error reporting

    - by phil harris
    I'm in the process of adding a Google Docs interface to my iPhone app, and I'm largely following the example in the GoogleDocs.m file from Tom Saxton's example app. The objective-c library I'm using is from http://code.google.com/p/gdata-objectivec-client/wiki/GDataObjCIntroduction The library file used is from gdata-objectivec-client-1.10.0.zip. This service:username:password method is a slight variant of the one found in the Saxton file GoogleDocs.m starting at line 351: - (void)service:(NSString *)username password:(NSString *)password { if(service == nil) { service = [[[GDataServiceGoogleDocs alloc] init] autorelease]; [service setUserAgent:s_strUserAgent]; [service setShouldCacheDatedData:NO]; [service setServiceShouldFollowNextLinks:NO]; (void)[service authenticateWithDelegate:self didAuthenticateSelector:@selector(ticket:authenticatedWithError:)]; } // update the username/password each time the service is requested if (username != nil && [username length] && password != nil && [password length]) [service setUserCredentialsWithUsername:username password:password]; else [service setUserCredentialsWithUsername:nil password:nil]; } // associated callback for service:username:password: method - (void)ticket:(GDataServiceTicket *)ticket authenticatedWithError:(NSError *)error { NSLog(@"%@",@"authenticatedWithError called"); if(error == nil) [self selectBackupRestore]; else { NSLog(@"error code(%d)", [error code]); NSLog(@"error domain(%d)", [error domain]); NSLog(@"localizedDescription(%@)", error.localizedDescription); NSLog(@"localizedFailureReason(%@)", error.localizedFailureReason); NSLog(@"localizedRecoveryOptions(%@)", error.localizedRecoveryOptions); NSLog(@"localizedRecoverySuggestion(%@)", error.localizedRecoverySuggestion); } } Please note the service:username:password method and the callback compile and run fine. The problem is that the callback is passing a non-nil NSError object. I added an NSLog() for every error reporting attribute of NSError and the (Xcode) log output of a test run is below. [Session started at 2010-05-27 12:27:16 -0700.] 2010-05-27 12:27:38.778 iFilebox[74596:207] authenticatedWithError called 2010-05-27 12:27:38.779 iFilebox[74596:207] error code(-1) 2010-05-27 12:27:38.780 iFilebox[74596:207] error domain(499324) 2010-05-27 12:27:38.781 iFilebox[74596:207] localizedDescription(Operation could not be completed.

I was hoping the localizedDescription would be more specific of the error. All I get for the error code value is -1, and the only description of the error is "Operation could not be completed. (com.google.GDataServiceDomain error -1.". Not very helpful. Does anyone know what a GDataServiceDomain error -1 is? Where can I find a full list of all error codes returned, and a description of what they mean?

  • UIButton only responds in a small area

    - by Tom Irving
    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () solution I managed to get to the bottom of this. I was fetching the event in question using a NSFetchedResultsController with a NSPredicate which I was releasing after I had the results. Retrieving values from the entities returned was no problem, but when I tried to update any of them it gave the error above. It should not have been released. oustanding part of my question What is a good way to create this sub list from a list of existing items in terms of a core data model. I don't believe its any of the ways I tried here. I need to show/edit it in another table view. Perhaps there is a better way than a boolean property on each event entity? The relationship idea above doesn't seem to work here (even though I can now create it). Cheers.

  • ViewController has wrong orientation after Landscape-only has been popped

    - by noroom
    In a navigation-based app, LandscapeViewController only supports landscape mode (all others support both modes). I also have a "loading screen" that advises the user to rotate the phone before continuing. This way I can make sure that when my landscape view loads, that it's in landscape mode. The problem comes when i rotate the phone to portrait mode while still showing LandscapeVC. I press the Back nagivation button to navigate up one level (to a VC that supports both landscape and portrait modes), but the upper level shows in landscape mode even though the phone is in portrait mode. I guess this is because when I left this view I was in portrait mode, I then rotated the phone while in another view, so this view has not received the notification. If I then proceed to rotate the phone to the other landscape mode (say the LandscapeVC was loaded on its right side, so I'd rotate the upper VC from portrait to the left landscape mode), it will update. My question is: how can I notify this upper view that the phone was rotated, so when the user goes up after putting the phone in portrait mode, the upper view shows correctly?

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • 3.1.3 and 3.2 different behaviour

    - by teo
    I'm using a custom cell in tableView with a UITextField - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease]; UITextField *txtField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 280, 24)]; txtField.placeholder = @"<Enter Text>"; txtField.textAlignment = UITextAlignmentLeft; txtField.clearButtonMode = UITextFieldViewModeAlways; txtField.autocapitalizationType = UITextAutocapitalizationTypeNone; txtField.autocorrectionType = UITextAutocorrectionTypeNo; [cell.contentView addSubview:txtField]; [txtField release]; } } This works fine and the UITextField covers the cell. When i run this with 3.2 sdk or on the iPad the UITextField isn't aligned properly to the left, overlapping the cell and i have to use a UITextField width of 270 instead of 280 UITextField *txtField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 270, 24)]; It seems something is wrong the pixel ratio. How can this be fixed? Is there a way to determine the version of os the device has ( 3.1.2, 3.1.3, 3.2 or maybe even the 4.0) or can it be done another way? Thank you Teo

  • Getting strange response on calling verifyReceipt to verify an in-app

    - by lostInTransit
    Hi I am making a call to verifyReceipt to validate an in-app purchase but am getting a very strange response (the response is b) The same code worked till some time back. But I stopped the app debugging while the trans was being verified at one point. From there on, the only response I get is b. I checked the code and it has nothing wrong. As I said, the same code worked till I stopped this trans mid-way. Any idea what could be wrong? Thanks.
