Thanks! I don't know why they introduced NSInteger. It sounds like it would be a subclass of NSNumber.
They did that so that NSData, etc. can hold a 63-bit amount of data in 64-bit applications while not shattering backward compatibility in 32- bit applications. Likewise, CGFloat was added so that 64-bit applications can use double-precision floating point for drawing while not shattering backward compatibility.
