  • UIActionSheet cancel button strange behaviour

    - by nevan
    I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons. I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController - (void)showOpenOptions { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application") delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link") otherButtonTitles:nil]; [sheet showInView:self.view]; [sheet release]; }

  • EXC_BAD_ACCESS when trying to release an ABRecordRef

    - by synic
    I've got the following class that is a wrapper around an ABPerson (ABRecordRef): @interface Recipient : NSObject { ABRecordRef person; } - (id)initWithPerson:(ABRecordRef)person; @end @implementation - (id)initWithPerson:(ABRecordRef)_person { if(self = [super init]) person = CFRetain(_person); return self; } - (void)dealloc { if(person) CFRelease(person); [super dealloc]; } @end I've left some of the methods out, but they aren't relevant to this question. Everything works fine, except I get an EXC_BAD_ACCESS on the if(person) CFRelease(person); line. Why does this happen? I'm not calling CFRelease or CFRetain at all anywhere else in my app.

  • Is there a way to iterate over all open windows in Mac OS X?

    - by Alex
    When you unplug an external monitor with a higher resolution that your macbook from your laptop, the windows mostly retain their width, but their size gets clipped to the (smaller) height of the macbook screen. When you plug the monitor back in, their size remains frustratingly small. My question is: is there any way that I can iterate over all open windows, save their size, and restore them once the monitor gets plugged in again?

  • @property, setter and getter question?

    - by fuzzygoat
    NSString *statusValue; NSString *currentValue; @property(retain, nonatomic) NSString *statusValue; @property(retain, nonatomic) NSString *currentValue; @synthesize statusValue; @sythnesize currentValue; Given the above, if I am setting one variable to another is it work doing ... [self setStatusValue: currentValue]; or should I use the property again and use [self setStatusValue: [self currentValue]]; I suppose the latter (although maybe overkill) does tell the reader that we are using one of the objects instance variables and not some local variable. just curious really ... gary

  • Document Based Application, preinitialize window (enter serial, buy, trial)

    - by Remizorrr
    I need to create several windows before NSDocument is loaded, or create a window that blocks NSDocument window and top menu. I tried several solutions - but they didn't work right. modal window, one after another. there were some problems with Async URLConnection, and some other problems with my NSDocument content. I created custom MainMenu.xib with no menu, that opens my preinitialize windows. here i found some other problems, when a file(associated with my application) is opened - the Document Window initializes. Here i tried to subclass NSDocumentController, but i found no way to pause the "open document". (i want the document to be opened anyway, but only after the preinitalize windows would be closed). So what is the right way to do this?

  • How to recreate the UITabBarItem image filter?

    - by boliva
    Hi, I'm writing a custom UITabBar replacement, and I would like to know how to recreate the filter that the built-in implementation does with the UITabBarItem image - that blue shining on selected tabs and gray gradient on unselected ones. I guess it's a matter of using the source image alpha value as a mask and overlay it with a pre-made blue (or whatever color) shining image and another one grayed out, but I would like to know what is the best approach from a code point of view. Best,

  • NSImage different size in code different shown by Finder/Preview

    - by krasnyk
    I have a couple of images that i use in my application(one of them is attached). The strange thing is that the real image size(shown by finder and preview) is 1200x701 px. When I access image from the code and as for its size, I get 360x210px. What is going on? Code I'm using to get the size of the image: NSImage *newImg = [[NSImage alloc] initWithContentsOfURL: [NSURL URLFromPasteboard:[sender draggingPasteboard]]]; float h = [newImg size].height; //height is 210px - should be 701px float w = [newImg size].width; //width is 320px - should be 1200px The content of the newImg is the same image that has been pointed and loaded - I display it in the NSImageView anyway so I see. Just the size taken with -size is wrong. This is the image:
