Shane, Sure. Well, it's all or nothing from the perspective of compiler flags. When you actually throw the switch from GC to ARC, it's just a one-shot. But you can prepare your code slowly, in a way that supports both. ex: - replace all use of NSAllocateCollectable with malloc/free - change 'retain' to 'strong' in property declarations - replace CFMakeCollectable with CFBridgingRelease - replace NSMakeCollectable with a nil check and CFBridgingRelease That's where I'm at anyway. I'm looking forward to the performance benefits of ARC, but will miss the GC programming model. -- ____________________________________________________________ Sean McBride, B.
