Question

I have this method to play an mp3:

- (void) playSound:(NSString*)sound{

    NSString *path = [NSString stringWithFormat:@"%@/%@",
                      [[NSBundle mainBundle] resourcePath],
                      sound];
    NSURL *filePath = [NSURL fileURLWithPath:path isDirectory:NO];
    player = [[AVAudioPlayer alloc] initWithContentsOfURL:filePath error:nil];
    [player prepareToPlay]; 
    [player play];  
}

everytime I call this method I get a new string “sound” and then I must alloc everytime this AVAudioplayer “player”; I want release it when I stop it or when it finish…is it possible?

Answer 1

Try the below instruction

yourViewController.h

 @interface yourViewController : UIViewController <AVAudioPlayerDelegate>

yourViewController.m file for add function

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
 //play finished
}

Declare the AVAudioPlayer Object below code

AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL
                                                                fileURLWithPath:[[NSBundle mainBundle] 
                                                                                 pathForResource:@"audio" ofType:@"mp3"]] error:NULL]; 

    audioPlayer.delegate = self;
    audioPlayer.currentTime=0.0f;
    [audioPlayer prepareToPlay];
    [audioPlayer play];

Thanks..!
