Im trying to update a UISlider with the current time from a AVPlayer

Question

I'm trying to update a UISlider with the current time from a AVPlayer. Im using a NSTimer to call a method with this code every 1 second:

CMTime duration = audioPlayer.currentTime; float seconds = CMTimeGetSeconds(duration); NSLog(@"duration: %.2f", seconds); nowPlayingSlider.value = seconds;

The Times being logged right but the uislider never updates.

Answer 1

Make sure you set the maximumValue property of the UISlider to the duration of the media. It defaults to 1.0.

Answer 2

For a UISlider, I always use:

[theSlider setValue:value animated:YES];

and, it works fine for me. Why do you want a Slider to update the time though? A UIProgressView could probably do want you want. Hope that helps!
