I have a simple little osx app that just starts up an IKPictureTaker and then saves the resulting picture as a .tiff file. It all seems to work fine but everytime I take the picture I get this error repeatedly: 2009-11-10 12:25:38.890 Take A Picture[855:9c23] *** QTCaptureSession warning: Session received the following error while de...

I created an object that conforms the NSComboBoxDataSource protocol, and implemented: - (NSInteger)numberOfItemsInComboBox:(NSComboBox *)aComboBox; - (id)comboBox:(NSComboBox *)aComboBox objectValueForItemAtIndex:(NSInteger)index; I set the instance of my NSComboBox...
Hi everyone, I am one of the great unwashed masses of .NET developers keen to try their hands at Mac OS X development. At the moment I am trying to figure out the various elements of Cocoa and getting a bit stuck on Core Data. I noticed most of the documentation and resources available on the Web involve a broad end-to-end tutorial, be...
I'm reading pixels from an area of the main screen via NSOpenGLContext. Now I would like to draw a rect around that area to indicate where it actually is. How would I do this? My first thought was the "Cocoa way": create a transparent fullscreen NSWindow and a custom NSView to draw the rectangle path. But that feels a bit too complicated...
Hi, I've a string that may or may not include C++ comments on it (multi-lin and single line) and I need to strip those comments out before being able to use that string. My current idea is to use an NSScanner to do that - find the position of opening and closing multi-line comments and delete that portion of the string and find the posi...
I may be missing something in the standard libs, but I don't think so. I have this current implementation: int char2hex(unsigned char c) { switch (c) { case '0' ... '9': return c - '0'; case 'a' ... 'f': return c - 'a' + 10; case 'A' ... 'F': return c - 'A' + 10; default: WARNING(@"pa...

One of the .h files: @interface MainViewController : UIViewController <APYahooDataPullerDelegate, CPPlotDataSource> { CPLayerHostingView *layerHost; @private APYahooDataPuller *datapuller; CPXYGraph *graph; } @property (nonatomic, retain) IBOutlet CPLayerHostingView *la...
Xcode comes with a few templates (file templates, project template, etc.). If you don't know what I'm talking about, take a look. After searching on Google for some time I couldn't find any other useful templates. So here it is: What are your most useful Xcode templates? I'll start with a pretty boring Objcetive-C category file temple....
This may be a dumb question but it seems like activateIgnoringOtherApps: may be the only way to activate an app using Cocoa. I have a java app that loads up a Cocoa app and I want the Cocoa app to be activated when this happens. The problem is I do not want to have to launch an intermediate app (some sort of controller) and use this ap...
I'm parsing some HTML with NSXMLParser and it hits a parser error anytime it encounters an ampersand. I could filter out ampersands before I parse it, but I'd rather parse everything that's there. It's giving me error 68, NSXMLParserNAMERequiredError: Name is required. My best guess is that it's a character set issue. I'm a little fuz...

Selecting the event in iCal shows a Window to edit the event, but does so by smoothly animating the window open and adding an arrow pointing to the even in the underlying calendar. Does anyone know what is ...
