NSMutableArray initialization methods

Is there a difference betwe开发者_Go百科en [NSMutableArray array] and [[NSMutableArray alloc] init] ?

[[NSMutableArray alloc] init] returns a mutable array that you own (and therefore have to explicitly relinquish ownership using release when you no longer need it) and [NSMutableArray array] returns a mutable array that you don't own.

According to the Memory Management Rules, any method with the word alloc, new, or create in the name, implies that you own the object returned from that method.
