Convert seconds to days, minutes, and hours in Obj-c

Question

In objective-c, how can I convert an integer (representing seconds) to days, minutes, an hours?

Thanks!

Answer 1

You will get days,hours,minutes and seconds from total seconds(self.secondsLeft)

days = self.secondsLeft/86400;
hours = (self.secondsLeft %86400)/3600;
minutes = (self.secondsLeft % 3600) / 60;
seconds = (self.secondsLeft %3600) % 60;

Code ......

  [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:@selector(updateCountdown) userInfo:nil repeats: YES];

-(void) updateCountdown {

    int days,hours,minutes,seconds;
    self.secondsLeft--;

    days = self.secondsLeft/86400;
    hours = (self.secondsLeft %86400)/3600;
    minutes = (self.secondsLeft % 3600) / 60;
    seconds = (self.secondsLeft %3600) % 60;

    NSLog(@"Time Remaining =%@",[NSString stringWithFormat:@"%02d:%02d:%02d:%02d",days, hours, minutes,seconds]);
}
