Is it wrong to use int in Cocoa and CocoaTouch?

Question

What is the advantage of using code NSIntegerinstead of intin code? I see this in the examples a lot, including samples of the official Apple code.

Answer 1

There is a similar question here at SO.com: In Cocoa, do you prefer NSInteger or int, and why? I prefer to use NSIntegerit because it's the future, Apple is now using it on top int, and this is the recommended way to do things.

But this is not "wrong" to use int.
