What would be the reason to use an NSInteger vs an int in iPhone programming? Thanks.

+1  A: 

An NSInteger is just a typedef with the following definition:

#if __LP64__ || NS_BUILD_32_LIKE_64
  typedef long NSInteger;
  typedef unsigned long NSUInteger;
#else
  typedef int NSInteger;
  typedef unsigned int NSUInteger;
#endif

As the typedef is defined differently basing on the platform, you can keep to use NSInteger independently from the platform.
