  • What is the performance difference between blocks and callbacks?

    - by Don
    One of the things that block objects, introduced in Snow Leopard, are good for is situations that would previously have been handled with callbacks. The syntax is much cleaner for passing context around. However, I haven't seen any information on the performance implications of using blocks in this manner. What, if any, performance pitfalls should I look out for when using blocks, particularly as a replacement for a C-style callback?

  • How to find the only UILabel in a view and hide it?

    - by tarnfeld
    I am adding a UILabel as a subview to a UIView and sometime later I want to hide it. It is assigned to a variable but I don't think setting the variables property Hidden after it's been added to the view will work (well it doesn't seem to anyway). Is there a way to loop through the subviews in a view and then find the one that has a specific tag or is of type UILabel that I could then remove?

  • iPhone - Change entity class (NSManagedObject) to make them initializable

    - by ncohen
    Hi everyone, I would like to use my custom NSManagedObject like a normal object (as well as its regular functions). Is it possible to modify the class in order to be able to initialize it like a normal object? [[myManagedObject alloc] init]; Thanks edit: to clarify the question, will it screw everything up if I change the @dynamic with @synthesize in the implementation?

  • Cocoa Scripting Bridge and <contents> element

    - by Stephen
    So, the application I'm trying to script has a scripting definition file that includes a <contents> element, which is an "implicitly specified container." The question, how do I get at what's inside this element using Scripting Bridge? Or alternatively, how do I send the Apple Event necessary to retrieve it and then transform what I get back into an SBObject? I already tried: [document nameOfKey] document.nameofKey [document contents] document.contents

  • Strange behavior: save video recorded within app?

    - by Josue Espinosa
    I allow the user to record a video within my app, then later play it again. When a user records a video, I save the URL of the video, then play the video later from the saved URL. I save the video both in the Photos app and in my app. If I delete the video within the photos app, it still plays. After about 7 days, the video gets deleted. I think I am saving in my tmp directory, but i'm not sure. Here is what I am doing: -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType]; [self dismissViewControllerAnimated:YES completion:nil]; // Handle a movie capture if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) { NSString *moviePath = [NSString stringWithFormat:@"%@",[[info objectForKey:UIImagePickerControllerMediaURL] path]]; NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; NSData *videoData = [NSData dataWithContentsOfURL:videoURL]; _justRecordedVideoURL = [NSString stringWithFormat:@"%@",videoURL]; AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; _managedObjectContext = [appDelegate managedObjectContext]; Video *video = [NSEntityDescription insertNewObjectForEntityForName:@"Video" inManagedObjectContext:_managedObjectContext]; [video setVideoData:videoData]; [video setVideoURL:[NSString stringWithFormat:@"%@",videoURL]]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; dateFormatter.dateStyle = NSDateFormatterLongStyle; [dateFormatter setDateStyle:NSDateFormatterLongStyle]; NSDate *date = [dateFormatter dateFromString:[dateFormatter stringFromDate:[NSDate date]]]; NSString *dateAdded = [dateFormatter stringFromDate:date]; [video setDate_recorded:dateAdded]; if(_currentAthlete != nil){ [video setWhosVideo:_currentAthlete]; } NSError *error = nil; if(![_managedObjectContext save:&error]){ //handle dat error } NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *tempPath = [documentsDirectory stringByAppendingFormat:@"/vid1.mp4"]; BOOL success = [videoData writeToFile:tempPath atomically:NO]; if(success == FALSE){ NSLog(@"Video was not successfully saved."); } if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath)) { UISaveVideoAtPathToSavedPhotosAlbum(moviePath, self, @selector(video:didFinishSavingWithError:contextInfo:), nil); } } } Am I saving it incorrectly? When I go to play the video, it works fine, after a couple days the video will play without audio, then eventually it will be gone. Any ideas why?

    - by Sheehan Alam
    I have a UIPresentationFormSheet (contains a textview) that appears in the center of the screen when I am in vertical orientation. When I dismiss the modal view, it disappears fine. When I am in horizontal orientation my modal view does not appear in the center of the screen. I have to dismiss my keyboard for the modal view to appear in the center. [self presentModalViewController:composeTweetController animated:TRUE]; When I dismiss the modal view in horizontal orientation the app automatically switches to vertical orientation. -(void)dismissComposeTweetView{ [self dismissModalViewControllerAnimated:TRUE]; } I want the following to happen: Modal view should appear in the center in horizontal orientation Modal view should disappear without switching to vertical orientation

  • How to backup data stored with Core Data - iPhone app?

    - by Alex
    I'm using sqlite for the persistent store, so could I just upload the .sqlite file to, for example, Amazon S3 as a way of providing users with the ability to backup their app data? Then for restoring just download it back and replace the existing .sqlite file in the app's folder. Does anybody see any issues with that? Has anyone done it? Any other suggestions on how to implement data backup feature?

  • Can I use drawRect to refresh a UIView subclass?

    - by Timbo
    I've created a subclass of UIView called Status which is designed to display a rectangle of a certain size (within a view) depending on the value of a variable. // Interface #import <Foundation/Foundation.h> #import <QuartzCore/QuartzCore.h> @interface Status: UIView { NSString* name; int someVariable; } @property int someVariable; @property (assign) NSString *name; - (void) createStatus: (NSString*)withName; - (void) drawRect:(CGRect)rect; @end // Implementation #import "Status.h" @implementation Status @synthesize name, someVariable; - (void) createStatus: (NSString*)withName { name = withName; someVariable = 10000; } - (void) drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); //Draw Status CGContextSetRGBFillColor(context, 0.0, 0.0, 1.0, 1); // fill CGContextFillRect(context, CGRectMake(0.0, 0.0, someVariable, 40.0)); } //// myviewcontroller implementation - (void) viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; myStatus = [[Status alloc] initWithFrame:CGRectMake(8,8,200,56)]; myStatus.backgroundColor = [UIColor grayColor]; [self.view addSubview:myStatus]; } How do I set this up so I can repeatedly call a refresh of the status bar? I'll probably call the refresh 4 times per second using a NSTimer, I'm just not sure what to call or if I should move this rectangle drawing to a separate function or something... Thanks in advance for your help :)

  • Removing object from NSMutableArray

    - by Ben Packard
    Just a small query... I stumbled across the following shortcut in setting up a for loop (shortcut compared to the textbook examples I have been using): for (Item *i in items){ ... } As opposed to the longer format: for (NSInteger i = 0; i < [items count]; i++){ ... } //think that's right If I'm using the shorter version, is there a way to remove the item currently being iterated over (ie 'i')? Or do I need to use the longer format?
