I don't understand the above claim; Why must the object returned by [super init*] be the one that is used? I'm certainly not aware of any limitation on an init method that would prevent it from… say… calling [super init], releasing whatever is returned if deemed unfit and then allocating an initializing some other instance. The documentation (http://developer.apple.com/library/mac/#documentation/cocoa/Conceptual/ObjectiveC/Articles/ocAllocInit.html) doesn't seem to make any such claim either. I haven't read beyond the above yet. Maybe the unstated assumption is explained? b.bum _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
