Answer 1

You should try this. see else part of method
-(void)playAudio
{
// [progreetimer invalidate];
// if([audioPlayer isPlaying]==YES)`enter code here`
if(self.isPlaying)
{
//Code to pause audioPlayer
[audioPlayer pause];
self.isPlaying = NO;
}
else
{
if(audioPlayer.url != nil && audioPlayer.duration != 0)
{
[audioPlayer play];
}
else
{
//Code to add new audioPlayer
}
}
}

Answer 2

Use the following code
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: nil];
[player prepareToPlay];
player.currentTime = 0;
[player play];
