Under The Bridge

[EDIT: Revised to highlight the drama!]

Here’s a couple handy tips for your collection of Objective-C debugging macros which made it to the front page of iPhoneKicks where we noticed it, but it appears — see comments below! — were lifted wholesale from this post a month earlier, and the apparent real author is on a mission to set the Internet straight. Heh. That’s kinda amusing in a goths-on-LJ kind of way, isn’t it now? But seriously, this does look like a rather tacky case of blog plagiarism, so we’re happy to spotlight the controversy. Stay tuned for rebuttals!

That said, wherever credit is properly due, these are still worth appropriating for yourself:

Tip #1: __PRETTY_FUNCTION__ will provide the Objective-C class name and method call.

#define ALog(format, ...) NSLog(@"%s:%@", __PRETTY_FUNCTION__,[NSString stringWithFormat:format, ## __VA_ARGS__]);
#define MARK	ALog(@"%s", __PRETTY_FUNCTION__);  

ALog ( @"My iPhone is an %@, v %@",
    [[UIDevice currentDevice] model],
    [[UIDevice currentDevice] systemVersion]);

Tip #2: Easy timer integration with NSTimeInterval.

#define START_TIMER NSTimeInterval start = [NSDate timeIntervalSinceReferenceDate];
#define END_TIMER(msg) 	NSTimeInterval stop = [NSDate timeIntervalSinceReferenceDate]; ALog([NSString stringWithFormat:@"%@ Time = %f", msg, stop-start]);

  START_TIMER;
  // do time intensive stuff
  END_TIMER(@"did time intensive stuff");

2008-24-12 12:34:56.789 MyApp[00000:000] -[MyAppDelegate myFunction:]:did time intensive stuff Time = 1.2345678

h/t: iPhoneKicks!
