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

Swift 3 version of onmyway133's answer:

import Foundation

func format(_ duration: TimeInterval) -> String {
    let formatter = DateComponentsFormatter()
    formatter.zeroFormattingBehavior = .pad
    formatter.allowedUnits = [.minute, .second]

    if duration >= 3600 {
        formatter.allowedUnits.insert(.hour)
    }

    return formatter.string(from: duration)!
}


print(format(12)) // 0:12
print(format(65)) // 1:05
print(format(1750)) // 29:10
print(format(3890)) // 1:04:50
print(format(45720)) // 12:42:00
