Recently I came across the question NSString: Why use static over literal? and in the comments arrived a new question.
In Objective-C there some "special" types that are just maps to C primitives. Like the NSInteger.
#if __LP64__ || (TARGET_OS_EMBEDDED && !TARGET_OS_IPHONE) || TARGET_OS_WIN32 || NS_BUILD_32_LIKE_64
typedef long NSInteger;
#else
typedef int NSInteger;
#endif
I know how to use the static keywords for objects but I don't understand the implications on C primitive types.
When should I use a static NSInteger x instead of NSInteger x? What happens with the memory in both cases?
