  • CoreData leak when reading a property

    - by Kamchatka
    Hello, I have the following code in a loop iterating over the different document objects: NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init]; [document primitiveValueForKey:@"data"]; [data writeToFile:filename atomically:NO]; [document.managedObjectContext refreshObject:document mergeChanges:NO]; [pool release]; The "data" property is a large blob (a 1MB image). And as I monitor the memory with the Allocation Instrument memory usage is increasing. I cannot find where the leak is coming from and how to remove it. Thanks!

  • Search pattern in string using regex in obj-c

    - by manileo86
    I'm working on a string pattern match algorithm. I use NSRegularExpression for finding the matches. For ex: I've to find all words starting with '#' in a string.. Currently I use the following regex function: static NSRegularExpression *_searchTagRegularExpression; static inline NSRegularExpression * SearchTagRegularExpression() { if (!_searchTagRegularExpression) { _searchTagRegularExpression = [[NSRegularExpression alloc] initWithPattern:@"(?<!\\w)#([\\w\\._-]+)? options:NSRegularExpressionCaseInsensitive error:nil]; } return _searchTagRegularExpression; } and I use it as below: NSRegularExpression *regexp = SearchTagRegularExpression(); [regexp enumerateMatchesInString:searchString options:0 range:stringRange usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) { // comes here for every match with range }]; This works properly. But i just want to know if this is the best way. suggest if there's any better alternative...

  • Vertically align UILabel

    - by Ashish Agarwal
    I am trying to vertically align the text in the UILabel view of my app. The problem is that I want the text to be vertically aligned to the top and the size of the label to be 280 x 150. I am only able to achieve one of these 2 things. If I remove the line [myLabel sizeToFit]; then the alignment of the text is alright but the size is messed up. But if I add the above line, then the alignment is messed up but the size is alright. How do I fix this problem. I've added the code below - CGRect labelFrame = CGRectMake(22, 50, 280, 150); UILabel *myLabel = [[UILabel alloc] initWithFrame:labelFrame]; [myLabel setText:finalRecipe]; [myLabel setBackgroundColor: [UIColor lightGrayColor]]; [myLabel setNumberOfLines:0]; [myLabel sizeToFit]; [self.view addSubview:myLabel];

  • Textures loaded with NSOperation are blank

Why is that?

  • Users adding views

    - by adamprocter
    I have created a main page (myAppViewController) and a add page rect button I have also created a page template (TemplateAViewController) all set up in Interface builder. I would like users to be able to add as many templates themselves and then page through them. I am not sure where to start. I can create views programmatic like so -(IBAction)createnewpage : (id) sender { myAppViewController *viewcontroller = [[myAppViewController alloc] initWithNibName:@"TemplateAViewController" bundle:[NSBundle mainBundle]]; [[self view] addSubview:viewcontroller.view]; } I then want to be able to navigate through these views- I guess I need to create a navigation controller to do this ?

  • Get nul value from one ViewController to one ViewController

    - by sovannarith
    I have 2 ViewControllers namely V1 and V2. I want to pass value from V2 to V1 but I get value 0 for countV1 in V1. I saw more questions in stackoverflow but I can't deal with this small problem. I use ARC. In V1 .h file @property(nonatomic,unsafe_unretained) int countV1; .m file @synthesize countV1; In V2 .m file int countV2 = 1; V1 *v1 = [V1 alloc] initWithNibName:@"V1" bundle:nil]; v1.countV1 = countV2;

  • MPMediaickerController memory leak identified by Leaks instrument

    - by Joe
    This is code from Apple's Addmusic example. MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker"); // The media item picker uses the default UI style, so it needs a default-style // status bar to match it visually [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES]; [self presentModalViewController: picker animated: YES]; [picker release]; I'm using this code in my app and the Leaks instrument highlights a leak on the line: [self presentModalViewController: picker animated: YES]; I think that this is because this line retains a reference to picker which cannot be subsequently released. Is there any way around this or is Leaks incorrectly identifying a leak?

  • Gesture recognizer for mouse down and up in iPhone SDK

    - by user545201
    I want to catch both mouse down and mouse up using gesture recognizer. However, when the mouse down is caught, mouse up is never caught. Here's what I did: First create a custom MouseGestureRecognizer: @implementation MouseGestureRecognizer -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesBegan:touches withEvent:event]; self.state = UIGestureRecognizerStateRecognized; } -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesEnded:touches withEvent:event]; self.state = UIGestureRecognizerStateRecognized; } @end Then bind the recognizer to a view in view controller: UIGestureRecognizer *recognizer = [MouseGestureRecognizer alloc] initWithTarget:self action:@selector(handleGesture:)]; [self.view addGestureRecognizer:recognizer]; When I click mouse in the view, the touchesBegan is called, but touchesEnded is never called. Is it because of the UIGestureRecognizerStateRecognized? Any advice will be appreciated! Thanks!

  • Load local Html file doesn't refer the js file in UIWebView

    - by Hero Vs Zero
    I am working with UIWebView project and I want to load an HTML file from a project resource. It is working fine when I run from the URL, but when I view the HTML file locally, JS files are not loaded. Loading the local HTML local file doesn't refer to js files in UIWebView. Here's my code to load the HTML file project local resource and does't refer the js file: NSString *path = [[NSBundle mainBundle] pathForResource:@"textfile" ofType:@"txt"]; NSError *error = nil; NSString *string = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error]; NSString *path1 = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL = [NSURL fileURLWithPath:path1]; NSLog(@"%@ >>> %@",baseURL,path); [webview loadHTMLString:string baseURL:baseURL]; This code doesn't find JS files in UIWebView, even though it loads image files from the project resource successfully.

  • Presenting an EKCalendarChooser modally

    - by pmb
    I'm trying to present the new EKCalendarChooser in my app as a modal view. I'm doing it using the following code: EKCalendarChooser *calendarChooser = [[EKCalendarChooser alloc] initWithSelectionStyle:EKCalendarChooserSelectionStyleMultiple displayStyle:EKCalendarChooserDisplayAllCalendars eventStore:self.ekDataSource.eventStore]; calendarChooser.showsDoneButton = YES; calendarChooser.showsCancelButton = NO; calendarChooser.modalTransitionStyle = UIModalTransitionStyleCoverVertical; calendarChooser.delegate = self; [[self navigationController] presentViewController:calendarChooser animated:YES completion:nil]; The problem I'm having is that when the view is displayed, it is missing the done button. If however, I display the view using the following code: [[self navigationController] pushViewController:calendarChooser animated:YES]; It works just fine. The done button is displayed. Shouldn't the done button be shown with the presentViewController call as well? Thanks in advance for any help! pmb

  • Displaying text in UILabel in iPhone

    - by SeniorLee
    OK. What's wrong with my code? - (void)viewDidLoad { [super viewDidLoad]; lblResult = [UILabel alloc]; } - (void)viewWillAppear:(BOOL)animated { lblResult.text = @"BlahBlah"; } I linked lblResult to Label object in IB well. But the label only shows the default text. Where's my BlahBlah?? And when the default string I set in the IB actually set to lblResult?? The reason that BlahBlah string is not displyed is I guess because lblResult.text is over-written by default string specified from IB. Just my guess. Can anyone make me clear with that?

  • My app crashes on Iphone SDK 3.2

    - by Mladen
    Hi Guys, My app worked ok on iPhone SDK 3.1. However, when I try to run it in 3.2 simulator, I get the following error and it crashes: bool _WebTryThreadLock(bool), 0x5148280: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now... Program received signal: “EXC_BAD_ACCESS”. When I debug it, it leads me to this peace of code: - (void)LoginViewToCheckView:(id)sender { CheckViewController *tempTestController = [[CheckViewController alloc] initWithStyle:UITableViewStyleGrouped]; [tempTestController setDelegate:self]; [self setCheckViewController: tempTestController]; [tempTestController release]; [navigationController pushViewController:checkViewController animated:YES];} Other thing worth mentioning is maybe that I am calling this function from a separate thread. Any ideas what could be wrong?

  • iPhone MVC Question

    - by HM1
    Hi, I'm bit of a newbie and had a basic question regarding adhering to the MVC model in iPhone coding. How do I setup a Model class that holds my data and connect it to different controllers in the following setup: Using Interface Builder, I created a tab controller in which - Tab #1 has a Nav Controller and a hierarchy of View Controllers. - Tab #2 has a View Controller So with what I have now, the View Controller under Tab #1 alloc init's the model class and I know how to pass the model from one ViewController to the next in the Navigation Hierarchy where it can pass the data and/or be updated with new data. Question is how to pass it from Tab #1's View Controller to Tab #2 View Controller as there is no code linking the two??? Thanks in advance, Hiren.

  • Locating the UIView that UITableView scrolls over

    - by Coocoo4Cocoa
    Hi all, I'm working on trying to obtain the UIView that UITableView scrolls over, if scrolling is enabled. Typically, the background is white, and if you push the UITableView out of its bounds, you'll see a background. I'm trying to set this background to a UIColor of blackColor. I can't seem to find the appropriate one to tag. I've tried the following code in my UIViewController: - (void)loadView { [super loadView]; UITableView *aTableView = [[[UITableView alloc] initWithFrame:self.view.bounds style:UITableViewStylePlain] autorelease]; [aTableView setScrollEnabled:YES]; [self.view setBackgroundColor:[UIColor blackColor]]; [self.view addSubview:aTableView]; self.tableView = aTableView; } The color still stays white. Seems I'm hitting the wrong UIView. Any idea? Thanks.
