Handle NSLog before release in iPhone

Go to your Build settings and under the Debug configuration add a value to "Preprocessor Macros" value like: DEBUG_MODE=1
Make sure you only do this for the Debug configuration and not for Beta or Release versions. Then in a common header file you can do something like:

#define DLog( s, ... ) NSLog( @"<%@:(%d)> %@", [[NSString stringWithUTF8String:__FILE__] lastPathComponent], __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__] )
#define DLog( s, ... )

Now instead of NSLog use DLog everywhere. When testing and debugging, you'll get debug messages.
