  • NSMutable String "Out of scope"

    - by Garry
    I have two NSMutableString objects defined in my viewController's (a subclass of UITableViewController) .h file: NSMutableString *firstName; NSMutableString *lastName; They are properties: @property (nonatomic, retain) NSMutableString *firstName; @property (nonatomic, retain) NSMutableString *lastName; I synthesis them in the .m file. In my viewDidLoad method - I set them to be blank strings: firstName = [NSMutableString stringWithString:@""]; lastName = [NSMutableString stringWithString:@""]; firstName and lastName can be altered by the user. In my cellForRowAtIndexPath method, I'm trying to display the contents of these strings: cell.detailTextLabel.text = [NSString stringWithFormat:@"%@ %@", firstName, lastName]; but this is causing the app to crash as soon as the view controller is displayed. Using the debugger, it seems that both firstName and lastName are "out of scope" or that they don't exist. I'm new to Xcode but the debugger seems to halt at objc_msgSend. What am I doing wrong?

  • Pushing to a UITable inside a UIView from a UITableview

    - by Michael Robinson
    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

  • Unrecognised selector sent to instance uitableview

    - by ct2k7
    I'm getting error: Unrecognised selector sent to instance, upon inspection, I see there is an issue in this section of code, and more specifically: [self.tableView insertSubview:ovController.view aboveSubview:self.parentViewController.view]; - (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar { if(searching) return; //Add the overlay view. ovController = [[OverlayViewController alloc] initWithNibName:@"OverlayView" bundle:[NSBundle mainBundle]]; CGFloat yaxis = self.navigationController.navigationBar.frame.size.height; CGFloat width = self.view.frame.size.width; CGFloat height = self.view.frame.size.height; //Parameters x = origion on x-axis, y = origon on y-axis. CGRect frame = CGRectMake(0, yaxis, width, height); ovController.view.frame = frame; ovController.view.backgroundColor = [UIColor grayColor]; ovController.view.alpha = 0.5; ovController.rvController = self; [self.tableView insertSubview:ovController.view aboveSubview:self.parentViewController.view]; searching = YES; letUserSelectRow = NO; //self.tableView.scrollEnabled = NO; } Looks like there's an issue with tableview?

  • How to push this view controller ?

    - by hib
    Hello all, I am caught in a strange requirement .See the following view hierarchy and scenario . I have a tab bar application in which I have three tabs . In first tab I am showing some content with a small image title and date (uitableview in navigation controller). In the detail view of that controller there are more buttons that shows different sorts of detail like gallery button and , more details button and some , more button . On tapping each button I will push each individual view controller in the main navigation controller . Now on the horizontal orientation I am showing same list of content but in the cover flow ( in modal view controller ) fashion like the ipod application . On tapping any image we will show the same buttons like gallery and more details and tapping on it will show the new controller with the following code : UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:myPhotoController]; UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonPressed)]; myPhotoController.navigationItem.leftBarButtonItem = backButton; [backButton release]; if([self.modalViewController isViewLoaded]){ [self dismissModalViewControllerAnimated:YES]; } modalNavController.navigationBar.barStyle = UIBarStyleBlackOpaque; [self presentModalViewController:modalNavController animated:YES]; [modalNavController release]; All this is working nicely . but when I get back the device in vertical orientation . the main modal controller will be dismissed and all the containing modal controller also will be dismissed if they are open or not . Instead of this what I want is If chooses an item in the coverflow and then if chooses gallery and if I put the device in vertical orientaion the gallery should be in the navigation hierarchy that drove me to the main list and gallery should be in horizonatal fashion . So what I want to do is that just to push the gallery controller in the main navigation hierarchy instead of showing from a madal controller . If someone wants reference then see the application "net a porter" I want to do like that . Just tell me how the controller hierarchy is working in that app . I need the help . Thanks

  • Managing several hundred occurrences of NSLocalizedString

    - by Gordon Hughes
    My application has several hundred points of localisation, some of which can be reused many times. To prevent from hunting and pecking through code to find occurrences of a particular NSLocalizedString, I create a macro for each in a header file using the #define preprocessor directive. For example: #define kLocFirstString NSLocalizedString(@"Default Text", @"Comment") #define kLocSecondString NSLocalizedString(@"More Text", @"Another comment") ... When I want to refer to a particular string, I do so by its macro name. This method has been working nicely for me, but I'm concerned that such blatant abuse of #define is frowned upon. From the standpoint of "correctness", should I just inline each NSLocalizedString with the code, or is there another method (extern NSString *aString; perhaps?) that I can use to collect the declarations in one place?

  • Reading email address from contacts fails with weird memory issue

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on?

  • Inactive area after device rotation

    - by Sébastien
    Hi all, I don't understand what's wrong in my very simple application with device rotation : I built my view with interface builder. (See screen capture here) I specified <key>UIInterfaceOrientation</key><string>UIInterfaceOrientationLandscapeRight</string> in my info.plist file. I had a (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {return YES;} in my root view controller. The area on the left (shown in red on the capture), around 20 pixel width, keeps inactive (nothing append if I hit a button in this area). In fact the full screen is active only in portrait mode, in landscape right mode there is this 20 pixels width inactive area, in landscape left mode this inactive area is on the right, in portrait upside down mode this area is on the bottom. I read lots of posts and documentation about UIView rotation, but I did not find anything to solve this problem (I tried to play with view.frame and view.bounds without any success). Anybody has an idea ? Thanks a lot. Regards. Sébastien.

  • How to provide an own contentView for using -drawRect?

    - by mystify
    I want to use -drawRect: in an UITableViewCell subclass but it is covered by contentView. So the best option seems to be that I make a UIView subclass with my -drawRect: code and use that as contentView. But how could I feed my UITableViewCell subclass with that contentView? UITableViewCell creates that on its own when the contentView property is accessed. Would I simply override the getter method and then provide my own view there?

  • Calculating File size before download

    - by sagar
    Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  • View controllers inside tab bar controller not auto-rotating

    - by Padawan
    In an iPad app, I have five regular view controllers (not navigation controllers or anything like that) inside a tab bar controller. The tab bar controller is just a plain UITabBarController declared in the app delegate. All the view controllers return YES in the shouldAutorotateToInterfaceOrientation method. On both the simulator and device, on rotation, the tab bar rotates properly but the currently selected view controller (call it A) does not. If I switch to another view controller B and then back to A (without rotating the device again), A appears correctly rotated. This happens with any of the five view controllers Why doesn't the currently selected view controller rotate and how do I fix it? Thanks.

  • Proper way to setup a UISegmentedControll on UINavigationController UINavigationBar all inside UITab

    - by Kaspa
    The title pretty much describes it all. The problem being the handling of the UISegmentedControll callbacks (button presses). If the content type of all of the nested views was the same (i.e. some UITableViewControllers) then I could just switch dataSource'es and reload the tables. However this is not the case, I have 3 very different views in there that allow further drilldown / interaction based on the NavigationControllers. So the way I have this set up ATM is that there is a "container" class that I put all of the UINavigationControllers in. They all share the same and one UISegmentedController and I redirect the callbacks to the container view controller. This does not feel too good at all. Additionally there is a problem when the user taps on the tab bar icon, the navigation controller pops to root which is ... the empty container view. Here's a picture of what I want to achieve:

  • UITableView Section Headers Drawing Above Front Subview

    - by hadronzoo
    I have a UITableView whose data have sections. I display an overlay view on top of tableView that dims it when searching: - (UIView *)blackOverlay { if (!blackOverlay) { blackOverlay = [[UIView alloc] initWithFrame:[self overlayFrame]]; blackOverlay.alpha = 0.75; blackOverlay.backgroundColor = UIColor.blackColor; [tableView insertSubview:blackOverlay aboveSubview:self.parentViewController.view]; } return blackOverlay; } This works perfectly as long as tableView does not contain sections. When tableView does contain sections and the tableView updates (such as when the view reappears after popping a view off of the navigation controller stack), the section headers are rendered above blackOverlay. This leaves tableView dimmed except for the section headers. I've tried calling [tableView bringSubviewToFront:self.blackOverlay] from within viewWillAppear:, but I get the same behavior. My current work-around is returning nil for tableView section headers while the overlay is present, but this leaves whitespace gaps in the overlaid tableView where the section headers were previously. How can I insure that tableView section headers are never drawn above blackOverlay? Or, is it possible to create a view in front of tableView from within a UITableViewController subclass that is not a subview of tableView?

  • Save downloaded content when in app purchase is complete

    - by jakob
    Hello experts! I have created an app which allows users to buy non-consumable content. The retrieving-ids-payment-process works like a charm. What i can't really figure out is how my content should be saved into the phone. The existing structure is that I have all my current content in Resources/packages/. For every package there is an matching entry in a package.plist. When the purchase is complete it is time to download the content from the server. What i retrieve from the server is a zip file with the new package that I have bought. My observer will call a method named provideContent: -(void) provideContent: (NSString*) productIdentifier { In here I will call my server and download the package } What i need from you guys is some sort of step by step walkthrough or tutorial of how, when the zip is retrieved(is zip allowed?), unpack this zip and add it to my current package structure. Thank you in advance

  • merging UIImagePickerController image with cameraOverlayView

    - by GameDev
    Im really in the need for some help and advice. Spent the last week on this and have now just become frustrated as i cant get it to work! Basically, im trying to merge two images into one image to display/save. First the user picks an image from album, it goes to edit image screen where user can move and scale the image. On this screen is an overlay image (320x480) for the person to align there eyes in. Once aligned I want to save this image (edited and overlay) into one and pass the image onto my next screen. It works fine when the image is filling the edit/crop box, but when the image is widescreen with top and bottom not filling the box, then when i save the image the coords of the overlay dont get saved correctly! Heres my code, ive tried various ways of doing this but have failed at every attempt :( - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the cropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // Combine image with overlay before saving!! image = [self addOverlayToImage:image]; overlayGraphicView.image = nil; // Take the picture image to the post picture view controller postPictureView = [[PostPictureViewController alloc] init:image Company:companyName withLink:buyButtonLink]; [picker pushViewController:postPictureView animated:YES]; [picker release],picker = nil; } The problem is that the image picked (originalImage) could be of any height, my overlayImage is however always 320x480, its almost all transparent with just two eye images in center which i want to save over the original images eyes! - (UIImage*) addOverlayToImage:(UIImage*)originalImage { CGRect cgRect =[[UIScreen mainScreen] bounds]; CGSize size = cgRect.size; UIGraphicsBeginImageContext(size); [originalImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* overlayImage = [UIImage imageNamed:overlayGraphicName]; [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); [finalImage retain]; UIGraphicsEndImageContext(); return finalImage; } I wish there was just an easy way to take a screenshot of whatever is in the edit crop box :( Please if someone could help me with this ASAP as I need to finish this in 1-2 days time! Thank you. EDIT:- I should also mention that with this I get the correct center of the screen and placement of the overlay on my next screen: [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; However, I am unable to work out the correct position of the main image especially as the height is different for every image if not fullscreen! I tried this to center it into the correct position but it doesnt work: [originalImage drawInRect:CGRectMake(0,(size.height/2 - originalImage.size.height/2), originalImage.size.width, originalImage.size.height)];
