Xcode\'s debugger console makes it easy to see any debugging messages my app sends out using NSLog(), but it always sticks a timestamp prefix on them:
Here is a macro I've made for this purpose. It works exactly like NSLog but with just your text, no extra info
Macro (paste to your .h)
#define CLog(__string, ...) fprintf(stderr, "\n%s", [([NSString stringWithFormat:__string, ##__VA_ARGS__]) UTF8String])
Example use:
CLog(@"I am %i days and %i years old", 3, 7);
Logs:
I am 3 days and 7 years old
