iOS Format String into minutes and seconds

Question

I am receiving a string from the YouTube JSONC api, but the duration is coming as a full number i.e 2321 instead of 23:21 or 2 instead of 0:02. How would I go about fixing t

Answer 1

Objective C:

NSDateComponentsFormatter * formatter = [[NSDateComponentsFormatter alloc]init];
[formatter setUnitsStyle:NSDateComponentsFormatterUnitsStyleShort];
[formatter setAllowedUnits:NSCalendarUnitSecond | NSCalendarUnitMinute];
[formatter setZeroFormattingBehavior:NSDateComponentsFormatterZeroFormattingBehaviorPad];
return [formatter stringFromTimeInterval:duration];
