Convert seconds into minutes and seconds

How can I convert seconds into minutes and seconds?

I am aware that 开发者_如何学Cyou can convert seconds to minutes like so, but I don't know how I can get the remainder of seconds...

int minutes = seconds / 60;

You will obtain minutes with :

int minutes = totalSeconds / 60;

and remaining seconds with:

int seconds = totalSeconds % 60;.

Here's a better answer from Convert Seconds Integer To HH:MM, iPhone

- (NSString *)timeFormatted:(int)totalSeconds{

  int seconds = totalSeconds % 60; 
  int minutes = (totalSeconds / 60) % 60; 
  int hours = totalSeconds / 3600; 

  return [NSString stringWithFormat:@"%02d:%02d:%02d",hours, minutes, seconds]; 
}

Swift version:

private func getFormattedVideoTime(totalVideoDuration: Int) -> (hour: Int, minute: Int, seconds: Int){
        let seconds = totalVideoDuration % 60
        let minutes = (totalVideoDuration / 60) % 60
        let hours   = totalVideoDuration / 3600
        return (hours,minutes,seconds)
    }

Swift

/** Returns the seconds as in clock format 02:24  */
    class func formatMinuteSeconds(_ totalSeconds: Int) -> String {

        let minutes = Double(totalSeconds) / 60;
        let seconds = totalSeconds % 60;

        return String(format:"%02d:%02d", minutes, seconds);
    }

You can resolve this problem with NSMeasurement and NSUnitDuration. These classes require iOS 10.0+, tvOS 10.0+, macOS 10.12+ or watchOS 3.0+. The code below converts seconds to minutes and seconds.

int seconds = 230;
NSMeasurement* measurement = [[NSMeasurement alloc] initWithDoubleValue:seconds unit:NSUnitDuration.seconds];
NSMeasurement* measurementMinutes = [measurement measurementByConvertingToUnit:NSUnitDuration.minutes];
int minutes = floor(measurementMinutes.doubleValue);
NSMeasurement* measurementMinutesWithoutSeconds = [measurement measurementBySubtractingMeasurement:[[NSMeasurement alloc] initWithDoubleValue:minutes unit:NSUnitDuration.minutes]];
int secondsRemainder = floor([measurementMinutesWithoutSeconds measurementByConvertingToUnit:NSUnitDuration.seconds].doubleValue);
NSLog(@"%d %d", minutes, secondsRemainder); // 3 50

Swift 5:

String with format hh:mm:ss

extension Float {

    var hoursMinutesSecondsFormat : String {
    let seconds = self.truncatingRemainder(dividingBy: 60).rounded(.toNearestOrAwayFromZero)
    let minutes = (self / 60).truncatingRemainder(dividingBy: 60).rounded(.toNearestOrAwayFromZero)
    let hours   = (self / 3600).rounded(.toNearestOrAwayFromZero)
    return String(format:"%02.f:%02.f:%02.f", hours,minutes, seconds);
    }
   
}

DateComponentsFormatter: A formatter that creates string representations, by using unitsStyle u can get a string as you want and mention allowedUnits. e.g: output for unitsStyle:: for 10000 secods

1. full = "2 hours, 46 minutes, 49 seconds"

2. positional = "2:46:40"

3. abbreviated = "2h 46m 40s"

4. spellOut = "two hours, forty-six minutes, forty seconds”

5. short = "2hr,46 min,40 sec"

6. brief = "2hr 46min 40sec"

   Easy to use:

    let time = convertSecondsToHrMinuteSec(seconds: 10000)
   
    func convertSecondsToHrMinuteSec(seconds:Double) -> String{
            let formatter = DateComponentsFormatter()
            formatter.allowedUnits = [.hour, .minute, .second]
            formatter.unitsStyle = .full
   
            let formattedString = formatter.string(from: TimeInterval(seconds))!
            print(formattedString)
            return formattedString
        }
