CALayer and Memory Management

I'm at a loss when it comes to releasing CALayers. Since you can only create a layer with [CALayer layer] (docs advise not to use [[CALayer alloc] init]), I would assume that the instance is automatically qutoreleased. However, after looking through apple's sample code on a menu built with core animation, the layers were autoreleased in the dealloc method (this doesn't work too well if the layers aren't instance variables). Additionally, when I tried releasing the layers after I was done with them (after I added them to a superlayer), sometimes it would freak out and crash, and other times it wouldn't mind. Basically, here's my question: When (if ever) are you supposed to (auto)release CALayers? -- 定魅刀利 Dimitri Bouniol email@hidden http://www.appkainime.com/
