I've been using CGPostMouseEvent() for performing mouse clicks since mac os 10.4. While working on my code and trying to make it 100% compatible with Snow Leopard, XCode spit a warning saying that CGPostMouseEvent() is deprecated.

Hey there, in Xcode 3.1.2 I used to load the nib of the NSCollectionViewItem in my subclass of NSCollectionViewItem like this: -(id)copyWithZone:(NSZone *)zone { id result = [super copyWithZone:zone]; [NSBundle loadNibNamed:@"PersonView" owner:result]; return result; } In Xcode 3.2 under 10.6 the same method doesn't ...
Hi, My question may be a bit stupid, but why can't any object instantiated in IB handle, say, button click? I mean I'm able to add my own object to a xib, and link outlets to cotrols and control actions to object's method, but once I press the button everything just crashes (uknown selector). Do you guys have a hint around that? EDIT:...

We need to write some software that will compile and run on both an Mac OS X server and Ubuntu. We would love to use Objective-C with all of its Cocoa goodness, however the GNUstep implementations of the parts we are using are broken (in the latest Ubuntu package anyway.) In light of this should we use C++ (I would really rather not), C...
