I'm running into a very annoying issue developing javascript for a UIWebView in an iPhone application. If there is an error in the javascript, it silently fails and halts execution of the function it was running. And some errors do not happen in a desktop browser, so all appears fine. I then run it on an iPhone and get a massive failu...
Hello, I am recently trying to connect my cocos2d game with open feint, but I can't accomplish it as there seem to be some settings missing in my build settings of any project that I create. For example, I have to check "Call c++ Default ctors/Dtors in objective c", but there isn't such an option in my build settings. What's wrong wi...
My class contains an UIImage property which I want to enforce as a 'copy' property by any external clients accessing it. But, when I try to do a copy in my custom setter, I get the runtime error about UIImage not supporting copyWithZone.

This is my first ever attempt at a Objective-c cocoa program, so I have no clue why it is giving me that error. I really don't understand the Build Result page either. myClass.h #import <Cocoa/Cocoa.h> @interface myClass : NSObject { int a; int b; } -(void) setvara:(int)x; -(void) setvarb:(int)y; -(int) add; @end myClass....
Binding a popup menu to an array controller with the path selection.type works fine. Binding a popup menu to a document controller with the path currentDocument.arrayController.selection.type works one way only (changes in selection are not propagated to the popup menu).

I have heard that when you have a subclass, you are supposed to initialize the superclass with the same init function from within the subclass's init. What I mean is that the subclass's init should call [super init] and the subclass's initWithFrame should call [super initWithFrame]. Why is this? Why does calling the super's init from ...
Hello everybody, I am using Erica Sadun's method of Asynchronous Downloads (link here for the project file: download), however her method does not work with files that have a big size (50 mb or above). If I try to download a file above 50 mb, it will usually crash due to a memory crash. Is there anyway I can tweak this code so that it w...

I have a weird situation that has been puzzling me for weeks. My project, Textual, is an IRC client for Mac OS X. It works great except one problem.
