Using UISlider or UIProgressView to Display and Control the Playback Progress of AVAudioPlayer

While implementing audio playback with AVAudioPlayer, you may need to display the playback progress with UIProgressView, or even to synchronize the state of the player with UISlider. AVAudioPlayer doesn’t have any functionality to get periodically notified about the current playback position. However, it has 2 aptly named properties that represent the time of the current playback position and the duration of the audio file: currentTime and duration respectively.
