AVAudioPlayer currentTime
@property NSTimeInterval currentTime
Discussion of [AVAudioPlayer currentTime]
If the sound is playing, currentTime is the offset of the current playback position, measured in seconds from the start of the sound. If the sound is not playing, currentTime is the offset of where playing starts upon calling the play method, measured in seconds from the start of the sound.
By setting this property you can seek to a specific point in a sound file or implement audio fast-forward and rewind functions.
