Question

@property (nonatomic, assign) Class aClass;

or

@property (nonatomic, retain) Class aClass;

Note: “Class” is that “Class” defined in objc.h

and does it need a release in the dealloc method?

Answer 1

Since it’s a pointer to a class object, and class objects live for the lifetime of the app, memory management actions like retain and release have no effect on it. So it shouldn’t matter whether you use assign or release. It would be simpler to use assign.
