You should do this instead: - (id) init { [super init]; myNotes = [[NSMutableArray alloc] init]; return self; }Actually, it should really be like this (I've been pedantically explicit):- (id)init { self = [super init]; if(self != nil) { myNotes = [[NSMutableArray alloc] init]; } return self; } Note that -init is NOT required to return the same object that "self" refers to. Therefore it is always required that you re-assign self in your overridden initializer if you need to access it, and you must return that modified self*. --Kyle Sluder
Of course you're correct here, and right to be absolutely pedantic in regards to how to write an init method properly. In the case of the original question, NoteController and Note were both subclasses of NSObject which I believe should behave as expected in the my example.
To indulge my own curiosity, in a case like this where you know the behaviour of the superclass like NSObject, is there any advantage to doing it Kyle's way as opposed to my example?
