Useful macros for iOS projects

I usually use a bunch of macros which makes my life easier when developing iOS apps. I hope you find it as useful as I do!

Macros collection, found it at: https://gist.github.com/numo16/3407652

Aditionally, I use these macros to help me to debug (instead of using NSLog):

• DLog will output like NSLog only when the DEBUG variable is set.
• ALog will always output like NSLog.

• ULog will show the UIAlertView only when the DEBUG variable is set.

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