No. You missed nothing. That's all. Objective-C is higher level language look like C. Low level control is not required.

Cocoa classes are designed for easier use than efficiency. If you want to deal with performance, you have an option of raw C (or C++) implementation. Otherwise, just use easy way. Of course, early-optimization is evil.

If you want a kind of encapsulation, just make a new class which contains NSMutableArray within it. Hide inner NSMutableArray and just expose what you want. But you'll realize this is unnecessary.
