If I have an NSTimeInterval that is set to say 200.0, is there a way to convert that into 00:03:20, I was thinking I could initialise an NSDate with it and then use NSDateFormatter using HH:mm:ss. My question is, is there a quick way to do this or do I have to break up the number myself and use [NSString stringWithFormat: %02d:%02d:%02d, myHour, myMin, mySec]
?
