AVAudioPlayer EXC_BAD_ACCESS

问题

I am trying to pause the AVAudioPlayer if it is currently playing. When I debug my code and check AVAudioPlayer, I see it is allocated. When I try to access a method/property on it (i.e. myAudioPlayer isPlaying), I get an EXC_BAD_ACCESS error. This happens if the AVAudioPlayer does not have a sound loaded. Is there a way I can do a check to see if it has loaded a sound? I tried accessing myAudioPlayer.data, but I still get the same error.

回答1:

I guess you have to use prepareToPlay method to find whether it has loaded or not.

回答2:

For me it was because I wasn't calling the one of the designated initialisers. I was instantiating it with AVAudioPlayer() instead of the designated initialisers which are public init(contentsOfURL url: NSURL) throws and public init(data: NSData) throws

回答3:

As of iOS 13, make sure you are removing the initialization on AVAudioPlayer before asigning it with AVAudioPlayer(contentsOf: URL(...))

i.e. change var audioPlayer = AudioPlayer() to var audioPlayer: AVAudioPlayer!

First you have to add AVFoundation Framework.Then,import AVFounadtion framework in .h file.

.h:

 AVAudioPlayer *audioPlayer;

.m:

    NSURL *url1 = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audio1.mp3", [[NSBundle mainBundle] resourcePath]]];

    NSError *error;
    audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url1 error:&error];
    //audioPlayer.numberOfLoops = 0;

        [audioPlayer play];

Try this code it may help you..
