I'd like to use a CALayer object as a key in a dictionary. The reason is that when my app detects a hit in a layer, I need to quickly determine which object I've associated with it. Since I can't store a reference to an arbitrary object in the CALayer, a dictionary seems to be the most expedient way to do that.
Unfortunately, I can't seem to add my layer as the key (it fails with "-[CALayer copyWithZone:]: unrecognized selector sent to instance 0x50132a0"). It's really pretty handy to be able to use any object as a key, why is this not the case in Obj-C?
