iOS Objective C - tic toc equivalent

[Car123]

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?

 

[dantastic]

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
