    - by john

This is in a brand new navigation project. Does anyone know why I get this behaviour?

  • Issue with UITextView in an animation block

    - by collin
    I'm having an issue with a UITextView inside another UIView whose frame is manipulated in an animation block when the keyboard displays. During the animation block the UIView scales beautifully and as expected, but the UITextView jumps out of it's superview(the UIView being animated) at the start of the animation. By the end of the animation, the UITextView ends up in the right place... what gives? Can anybody explain why the UITextView is jumping out of it's container view at the start of the animation? Thanks in advance.

  • How do I open iPhone camera and restrict to a frame?

    - by Thomas
    Hello All: I'd like to know how to open the camera inside of a pre-defined frame (not the entire screen). When the view loads, I have a box, and inside it, I want to display what the camera sees. I don't want to snap a picture, just basically use the camera as a viewfinder. I have searched this site and have not yet found what I'm looking for. Please help. Thanks! Thomas

  • Popping multiple levels in UITableViewController

    - by LavaSlider
    I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed. I tried: [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; [self.navigationController popViewControllerAnimated: NO]; and [self.navigationController popViewControllerAnimated: NO]; [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

  • How to make NSView not clip its bounding area?

    - by Jeremy L
    I created an empty Cocoa app on Xcode for OS X, and added: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.view = [[NSView alloc] initWithFrame:NSMakeRect(100, 100, 200, 200)]; self.view.wantsLayer = YES; self.view.layer = [CALayer layer]; self.view.layer.backgroundColor = [[NSColor yellowColor] CGColor]; self.view.layer.anchorPoint = CGPointMake(0.5, 0.5); self.view.layer.transform = CATransform3DMakeRotation(30 * M_PI / 180, 1, 1, 1); [self.window.contentView addSubview:self.view]; } But the rotated layer's background is clipped by the view's bounding area: I thought since some version of OS X and iOS, the view won't clip the content of its subviews and will show everything inside and outside? On iOS, I do see that behavior, but I wonder why it shows up like that and how to make everything show? (I am already using the most current Xcode 4.4.1 on Mountain Lion). (note: if you try the code above, you will need to link to Quartz Core, and possibly import the quartz core header, although I wonder why I didn't import the header and it still compiles perfectly)

  • How does the NSAutoreleasePool autorelease pool work?

    - by jsumners
    As I understand it, anything created with an alloc, new, or copy needs to be manually released. For example: int main(void) { NSString *string; string = [[NSString alloc] init]; /* use the string */ [string release]; } My question, though, is wouldn't this be just as valid?: int main(void) { NSAutoreleasePool *pool; pool = [[NSAutoreleasePool alloc] init]; NSString *string; string = [[[NSString alloc] init] autorelease]; /* use the string */ [pool drain]; }

  • Cocoa - NSFileManager removeItemAtPath Not Working

    - by Kevin
    Hey there everyone, I am trying to delete a file, but somehow nsfilemanager will not allow me to do so. I do use the file in one line of code, but once that action has been ran, I want the file deleted. I have logged the error code and message and I get error code: 4 and the message: "text.txt" could not be removed Is there a way to fix this error "cleanly" (without any hacks) so that apple will accept this app onto their Mac App Store? EDIT: This is what I am using: [[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL]; Thanks, kevin

  • Added buttons, webview, added outlets, but can't play with them in the code...

    - by Tom
    Hi! I made a toolbar with two buttons on it. I then created two outlets in my class controller. Then I hooked the the controller to the buttons and selected the outlets. Finally I rewritten the class files (that added: IBOutlet id next; IBOutlet id previous; to my .h file). So now, everything looks okay. But then I try somewhere in the code to change the state of one of my button like this: next.enabled = YES; I tried with self. too but unfortunately I receive this error message: error: request for member 'enabled' in something not a structure or union Do you have any idea of what's happening there? And yes I have: #import <UIKit/UIKit.h> :) Using: [next setEnabled:YES]; gives me no error but still doesn't work... And finally, for documenting purposes here's the whole method: - (void)viewDidLoad { [super viewDidLoad]; if (!self.currentLevel) { self.currentLevel = @"1"; } NSArray *etape = [self.etapes objectForKey:self.currentLevel]; if ([etape count] > 0) { self.navigationItem.title = [etape objectAtIndex:1]; if ([etape count] > 1) { [next setEnabled:YES]; } } else { self.navigationItem.title = @"Aucune étape"; } } When I do: NSLog(@"%@", [next class]); It returns (null) ... I guess it is supposed to be UIBarButtonItem... It seems that it is impossible to play with any outlets even if I don't receive any errors while playing with them...

  • TTThumbView/TTPhotoView no autorotation

    - by ludo
    Hi, In my app I try to use the TTphotoView, so in a ViewController I push the TTphotoView with my navigationController like this: if(self.photoViewController == nil { PhotoViewController *viewController = [[PhotoViewController alloc] init]; self.photoViewController = viewController; viewController.hidesBottomBarWhenPushed = YES; [viewController release]; } [self.navigationController pushViewController:self.photoViewController animated:YES]; [self.navigationController  dismissModalViewControllerAnimated:YES] the problem is when the user rotate the device on the PhotoViewController nothing happen. EDIT : I can't believe people didn't have the same problem. If someone use the photoView in his application with his own navigation and not the TTNavigation can he tell me how did he push the ViewController?

  • Getting random objects from an array, and if the objects are the same, get a new object.

    - by XcodeDev
    Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

  • Custom UITableViewCell not appearing when row height is set

    - by Sheehan Alam
    I have a custom UITableViewCell which I have created in IB. My labels display when I don't over-ride: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath however my content is squished. I want the height to be 120px so I have the following: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight = 120; return rowHeight; } I'm not sure why the content inside of my UITableViewCell all of a sudden disappears?

  • Subclass not seeing superclass' instance variable

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? If I make this ivar a property then I can access it by self.x. What's worse is sometimes the error disappears, so something in my code is obviously causing this error but I cannot figure it out.

  • Modifying NSDate to represent 1 month from today

    - by bmalicoat
    I'm adding repeating events to a Cocoa app I'm working on. I have repeat every day and week fine because I can define these mathematically (3600*24*7 = 1 week). I use the following code to modify the date: [NSDate dateWithTimeIntervalSinceNow:(3600*24*7*(weeks))] I know how many months have passed since the event was repeated but I can't figure out how to make an NSDate object that represents 1 month/3 months/6 months/9 months into the future. Ideally I want the user to say repeat monthly starting Oct. 14 and it will repeat the 14th of every month.

  • Simplest way to use NSTableView?

    - by Nick Brooks
    Can I use NSTableView like I've used ListView in Windows? By that I mean JUST adding rows to the view. I need to display a very simple two columned table and I don't want to write all this data related crap. Can I just 'add' stuff to a table view? If not what is the simplest way to do what I'm trying to do (preferably without data sources)?
