• Reason why UIImageView gives me a 'distorted' image sometimes

  - by Cedric Vandendriessche

  I have a custom UIView with a UILabel and a UIImageView subview. (tried using UIImageView subclass aswell). I assign an image to it and add the view to the screen. I wrote a function which adds the amount of LetterBoxes to the screen as there are letters in the word: - (void)drawBoxesForWord:(NSString *)word { if(boxesContainer == nil) { /* Create a container for the LetterBoxes (animation purposes) */ boxesContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 205, 320, 50)]; [self.view addSubview:boxesContainer]; } /* Calculate width of letterboxes */ NSInteger numberOfCharacters = [word length]; CGFloat totalWidth = numberOfCharacters * 28 + (numberOfCharacters - 1) * 3; CGFloat leftCap = (320 - totalWidth) / 2; [letters removeAllObjects]; /* Draw the boxes to the screen */ for (int i = 0; i < numberOfCharacters; i++) { LetterBox *letter = [[LetterBox alloc] initWithFrame:CGRectMake(leftCap + i * 31 , 0, 28, 40)]; [letters addObject:letter]; [boxesContainer addSubview:letter]; [letter release]; }} This gives me the image below: http://www.imgdumper.nl/uploads2/4ba3b2c72bb99/4ba3b2c72abfd-Goed.png But sometimes it gives me this: imgdumper.nl/uploads2/4ba3b2d888226/4ba3b2d88728a-Fout.png I add them to the same boxesContainer but they first remove themselves from the superview, so it's not like you see them double or something. What I find weird is that they are all good or all bad.. This is the init function for my LetterBox: if (self == [super initWithFrame:aRect]) { /* Create the box image with same frame */ boxImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height)]; boxImage.contentMode = UIViewContentModeScaleAspectFit; boxImage.image = [UIImage imageNamed:@"SpaceOpen.png"]; [self addSubview:boxImage]; /* Create the label with same frame */ letterLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height)]; letterLabel.backgroundColor = [UIColor clearColor]; letterLabel.font = [UIFont fontWithName:@"ArialRoundedMTBold" size:26]; letterLabel.textColor = [UIColor blackColor]; letterLabel.textAlignment = UITextAlignmentCenter; [self addSubview:letterLabel]; } return self;} Does anyone have an idea why this could be? I'd rather have them display correctly every time :)

• Get notification when NSOperationQueue finishes all tasks

  - by porneL

  NSOperationQueue has waitUntilAllOperationsAreFinished, but I don't want to wait synchronously for it. I just want to hide progress indicator in UI when queue finishes. What's the best way to accomplish this? I can't send notifications from my NSOperations, because I don't know which one is going to be last, and [queue operations] might not be empty yet (or worse - repopulated) when notification is received.

• UISwitch quick toggle multiple times.

  - by Tejaswi Yerukalapudi

  I was playing around my app and I was toggling a UISwitch really fast (who can resist?). So, I toggled it really fast for 10-15 times, an array that should contain the data from the table view cell that I have my switch in either has extra copies of the same cell sometimes, just one copy (the correct case) a few times and no data in it at all some times. The app works fine if it's toggled at normal speed. I'm pretty sure this scenario won't really happen with my users, but I'm still curious as to why it's happening. Thanks, Teja

• Returning NSNull from actionForLayer:forKey

  - by MrHen

  If I implement the CALayer delegate method actionForLayer:forKey I can return [NSNull null] to force the CALayer to not animate any changes. Unfortunately, [NSNull null] doesn't implement the CAAction delegate and XCode kicks out the following warning: warning: class 'NSNull' does not implement the 'CAAction' protocol Here is the method code: - (id<CAAction>)actionForLayer:(CALayer *)theLayer forKey:(NSString *)theKey { //This disables the animations when moving things around //Also, don't animate the selection box. It was doing weird things if(undoGroupStarted || theLayer == self.selectionBox) { return [NSNull null]; } else { return nil; } } Am I doing something wrong? Is returning [NSNull null] bad behavior? If so, what is another way to do what I am trying to do here? If not, how do I make the compiler happy?

• Multi-property "transactions" in Core Data / NSManagedObject / NSFetchedResultsController?

  - by Martijn Thé

  Hi, Is it possible to set multiple properties of an NSManagedObject and have the NSFetchedResultsController call controllerDidChangeContent: only once? In other words, is it possible to say something like: [managedObject beginChanges]; [managedObject setPropertyA:@"Foo"]; [managedObject setPropertyB:@"Bar"]; [managedObject commitChanges]; and then have the NSFetchedResultsController call controllerDidChangeContent: (and the other methods) only one time? Thanks!

• xCode complitions, spelling checkings stoped

  - by SentineL

  My xCode 4.3.2 stopped to show up spelling errors and completions for code. The only way to find out if there is any error in the code - build it. xCode colores only keywords such as if, else, for etc. All other code hasn't colored. Shown only a few very strange completions. For example: CGPoint p; p.y // complition is "YES" p.x // complition is "xor" Completions for methods calls are only nearaly used methods. How can I fix this? I rebooted my mac several times allready, and didn't find any staff obout this in xCode's preferences.

• Create an UIButton with "push button" appearance?

  - by Krumelur

  I want to create a button with the same look and feel as the "Timer" function in the builtin Clock app, but it really eludes me how to do it. By looking at the source code for UICatalog, it seems to create these buttons you need to create a custom bitmap. Is this true? If so, is there a "standard" bitmap that can be used, to ensure consistent user experience?

• UINavigationController crashes after pushing 3 views onto stack

  - by joec

  I have a navigation controller, which has the following structure: Category Item Item Detail I can choose a category, and then choose an item to see its details. I can do this twice, i.e. go Back to the list of items and select another item. If i try this a third time, the app crashes, I get objc_msgSend in stack but thats all. But, instead of choosing another item, i go to the list of categories, and choose a different category, I can select two items in that category, before it crashes also. What would be causing this? Thanks

• Setting Corner Radius on UIImageView not working

  - by MarkPowell

  I'm at a bit of a loss. I've used the layer property of UIView to round the corners of multiple elements in my app. However, this one UIImageView is simply not complying. Not sure what I am missing. The UIImageView (called previewImage) is contained in a Table View Cell. I've tried setting the cornerRadius property multiple location (in the cell itself and in the controller that creates the cell) to no avail. static NSString *CellIdentifier = @"MyTableViewCell"; MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil]; cell = [topLevelObjects objectAtIndex:0]; cell.previewImage.layer.cornerRadius = 20; //Made it 20 to make sure it's obvious. } Is there something about the way cells are loaded that I'm missing?

• pull down notification panel in iOS help for iPad

  - by Priya Chhabra

  I have developed an iPad application. In which I am using left/right swipes from corner of screen. The problem is when device is in landscape mode, (though the application is always in portrait orientation) and user wants to swipe left, it opens the notification panel instead of going to swipeAction that I had defined. Note that it works fine when device is kept in portrait mode. Is there any way to make pull down notification panel application orientation specific ? Any kind of help will be appreciated.

• Concept: Mapping irregular shapes (cartoons, sprites) to triangles in OpenGL ES

  - by Moshe

  I understand how mapping a triangle texture to a triangle works, but how do you map other things? I can't see myself mapping a circle onto a triangle. If it were a quad (square), I could see it happening, but why would a graphic not get warped on a triangle? EDIT: Bonus question: What are some good OpenGL ES tutorials online? Videos and articles count. (I've seen the Stanford University stuff on iTunes U and think it's excellent, but I want more.)

I have tried to pass as per below method. //ViewController.h @interface ViewController:UIViewController{ NSString *String; } @property(copy, nonatomic)NSString *String; @end //ViewController.m #import "ViewController1.h" ViewController1 *level1view = [[ViewController alloc]init]; level1view.hideBottomBarWhenPushed = YES; level1view.theString = String; [self.navigationController pushViewController:level1view animated:YES]; [level1view release]; //ViewController1.h NSString *theString; @property(copy, nonatomic)NSString *theString; This is working fine. but I want to pass more than one parameter like Integer and UITextFiled Values so how to do that? Is there any Apple Doc that I can get idea about this? Thanks,

• Creating Actions from UIActionSheets help

• How to manage a single-selection (exclusive) list?

  - by Andy

  I've got a detail view that consists of a table view with a few rows of data. I can fill the rows just fine, and moving back and forth from the parent view to the subview works too. This detail view should allow the user to select a single value, placing a checkmark accessory in the cell and then returning to the parent view (where the selected value becomes the cell.textLabel.text property of the cell from which the detail view was called). This all works as of right now. However, when the user taps the cell in the parent view to go back to the detail view (to change their selection), my checkmark has disappeared and I cannot for the life of me figure out how to make it stay. Here's my cellForRowAtIndexPath: method: - (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]; } NSString *labelText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumberLabel"]; cell.textLabel.text = labelText; NSString *currentLabel = [ruleBuilder.tableView cellForRowAtIndexPath:selectedIndexPath].textLabel.text; if (labelText == currentLabel) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } NSString *detailText = [[phones objectAtIndex:indexPath.row] valueForKey:@"phoneNumber"]; cell.detailTextLabel.text = detailText; return cell; } I've checked out Apple's sample code for exclusive-list management in Table View Programming Guide, but the snippet seems incomplete, and I can't find the related code in Apple's sample code. This doesn't seem like it ought to be that hard to do.
