More generally, you shouldn't really be invoking any method inside init* or dealloc methods

Care to elaborate?

If you're trying to be as defensive as possible, then you have to operate under the assumption that someone may have subclassed the class and overridden your public methods. These overrides may be assuming that when the method is invoked, all of the properties and ivars and everything are in a consistent and fully-initialized state.

So, if your initializer or dealloc method causes one of these overridden methods to be executed, then the logic of the method may do something incorrect. The best case scenario is that it works as intended. The worst case scenario is that you do something like dereference a NULL pointer or index beyond the bounds of an array or cause some data to become corrupted, etc.

Whilst you're inside an initializer or dealloc method, your object is in an inconsistent state. Thus, if you're trying to be as defensive as possible, you should avoid invoking methods that might be making assumptions about the state of the object.

Hey @davedelong. Thanks for the great writeup. This is now fixed.
