Objective C Custom Log Macros

CustomLog.m

#ifdef DEBUG
#   define DLog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)
#else
#   define DLog(...)
#endif

// ALog always displays output regardless of the DEBUG setting
#define ALog(fmt, ...) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__)

With current Xcode, you can make use of the z and t modifiers to handle NSInteger and NSUInteger without warnings, on all architectures.

You want to use %zd for signed, %tu for unsigned, and %tx for hex.
