Adding delay between execution of two following lines

Krishna Raj Salim picture Krishna Raj Salim · Mar 11, 2013 · Viewed 103.7k times · Source

I need to add delay between the execution of two lines in a(same) function. Is there is any favorable options to do this?

Note: I don't need two different functions to do this, and the delay must not affect other functions' execution.

eg:

line 1: [executing first operation];

line 2: Delay                        /* I need to introduce delay here */

line 3: [executing second operation];

Any help is appreciable. Thanks in advance...

You can use gcd to do this without having to create another method

double delayInSeconds = 2.0;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(delayInSeconds * NSEC_PER_SEC));
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
  NSLog(@"Do some work");
});

You should still ask yourself "do I really need to add a delay" as it can often complicate code and cause race conditions
