NSTimeInterval to HH:mm:ss?

Question

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 NSDateFo

Answer 1

straight from apple docs: in h file:

 @property(strong,nonatomic)NSDateComponentsFormatter *timerFormatter;

in m file

@synthesize timerFormatter;

- (void)viewDidLoad {
[super viewDidLoad];
NSDateComponentsFormatter *timerFormatter = [[NSDateComponentsFormatter alloc] init];
timerFormatter.unitsStyle = NSDateComponentsFormatterUnitsStylePositional; 
//10:59 Positional THIS ONE DOES NOT SEEM TO WORK iOS<9 WHEN <1Minute JUST SHOWS 01, 10m 59s Abbreviated, 10min 59sec Short, 10minutes 59seconds Full ...
timerFormatter.allowedUnits = NSCalendarUnitHour|NSCalendarUnitMinute|NSCalendarUnitSecond;
}

whereever you need to convert your NSTimeInterval timeInterval to hh:mm:ss string, do this:

NSString *txt=[timerFormatter stringFromTimeInterval:timeInterval];
