Improved Logging macros for Objective-C Development. These are modified versions of the solutions here: http://stackoverflow.com/questions/969130/how-to-print-out-the-method-name-and-line-number-and-conditionally-disable-nslog To disable DLog and ULog just a property or method to a class named dontLog

LoggerPlus.h

#ifdef DEBUG
#   define DLog(fmt, ...) if(![self respondsToSelector:@selector(dontLog)]) NSLog((@"%s [Line %d] " fmt), __PRETTY_FUNCTION__, __LINE__, ##__VA_ARGS__);
#else
#   define DLog(...)
#endif

#ifdef DEBUG
#   define ULog(fmt, ...)  if(![self respondsToSelector:@selector(dontLog)]) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"%s\n [Line %d] ", __PRETTY_FUNCTION__, __LINE__] message:[NSString stringWithFormat:fmt, ##__VA_ARGS__]  delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alert show]; }
#else
#   define ULog(...)
#endif

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