How to set music playback slider in music player

Question

Answer 1

Use a UISlider setting the maxValue to the current playing song duration (in seconds) and the minValue to 0.

Assuming that you're using an MPMusicPlayerController use the currentPlaybackTime to get the current time of the playing track and use that value to update the slider each second

slider.value = musicPlayerController.currentPlaybackTime;
slider.minimumValue = 0;
slider.maximumValue = [musicPlayerController.nowPlayingItem valueForProperty:@"MPMediaItemPropertyPlaybackDuration"];
