View Full Version : Objective C - tic toc equivalent
May 12, 2011, 04:38 AM
I need to find the time that a certain block of code is taking to execute. Is there a 'tic toc' equivalent in objective C, like there is in matlab for example?

NSDate *start = [NSDate date];
// doing stuff
NSTimeInterval milliseconds = [start timeIntervalSinceNow];

Using mach_absolute_time() (from the <mach/mach_time.h> include) is more accurate for timing small intervals than NSDate. NSDate can get "compensated" both forwards and backwards by network time.

ended up using CFAbsoluteTimeGetCurrent() and CFTimeInterval, works just fine for what I need :)
