You need to consider redesigning a little bit. What ever portion of code you expect to process after callback happens, let that code called by the callback. That way it will give you the guarantee that it always executes after the callback.

where you want to wait your functionality write this code [self performSelector:@selector(WaitForTwoSecond) withObject:nil afterDelay:2]; and implement - (void)WaitForTwoSecond { //write your code here } this method wait for two second and after that you cant access all data and put it in appropriate place .

we can say that this function is working like in background process
