Objective C - tic toc equivalent

Code:

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.
