While this is not a direct answer to Devang s question I believe that the below macro can be very helpful to people looking to log BOOLs  This will log out the value of the bool as well as automatically labeling it with the name of the variable    define LogBool BOOLVARIABLE  NSLog    s       BOOLVARIABLE  BOOLVARIABLE     YES      NO     BOOL success   NO  LogBool success      Prints out  success  NO  to the console  success   YES  LogBool success      Prints out  success  YES  to the console
