Question

I have a countdown timer that displays the number of seconds left on a audio track. For some reason the countdown is not counting at 1 second intervals, but 2 seconds on the first count and then 1 second on the next count. (It’s counting in this pattern – it jumps 2 seconds, then 1 over and over).

here’s my code:

// display current time left on the track
- (void)updateTimeLeft {
    NSTimeInterval timeLeft = self.player.duration - self.player.currentTime;

    // update your UI with timeLeft
    self.timeDisplay.text = [NSString stringWithFormat:@"%.2f", timeLeft / 60];

}

and here’s my NSTimer:

NSTimer * myTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(updateTimeLeft) userInfo:nil repeats:YES];

thanks for any help.

Answer 1

try this

 - (void)updateTimeLeft
{
NSTimeInterval timeLeft = self.player.duration - self.player.currentTime;

int min=timeLeft/60;

int sec = lroundf(timeLeft) % 60;

// update your UI with timeLeft
self. timeDisplay.text = [NSString stringWithFormat:@"%d minutes %d seconds", min,sec];
}

just an idea
