戏子无情 提交于 2019-11-28 15:38:49
问题 I have a date converted to double value and saved in database. Now, I want to compare if currentDate > myDataBaseDate + 8 hours i.e., I want to get 8 hours added to myDataBaseDate. I'm converting date into double values. So how do I get 8 hours later time from my database saved date. How do I compare if (currentDateTime > DateFromdatabaseValue + DateByAdding8HoursInDataBase) 回答1: I'm not entirely sure what you are trying to do, but you can create an NSDate object by adding time in seconds on

How to Kill/Stop a background thread?

人盡茶涼 提交于 2019-11-28 14:00:18
So I have a method that performs a loop and because of the way my program works i'm calling this method using, [self performSelectorInBackground:@selector(myMethod:) withObject:arg]; And the method itself, - (void)myMethod:(id)arg { //... for (//Loop Conditions) { if (stopMorse) { break; } //Do stuff } //... } Now I would like to allow the user to stop this loop from running, so is there a way of killing/stopping the thread. I've tried adding a BOOL but the problem is that it doesn't seem to get updated because it's on a separate thread. What is the best way to stop this loop from running?

UISearchBar Search table row with text, subtext and image
