iphone - 停止AVAudioPlayer

这是我的代码

 NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"95" ofType:@"wav"];

NSError *activationError = nil;
NSError *audioPlayerInitError = nil;
[[AVAudioSession sharedInstance] setActive: YES error:&activationError];

NSURL *newURL = [NSURL fileURLWithPath:soundFilePath];
musicPlayer1 = [[AVAudioPlayer alloc] initWithContentsOfURL:newURL error:&audioPlayerInitError];

if (musicPlayer1) {
    [musicPlayer1 stop];
    [musicPlayer1 release];
    musicPlayer1 = nil;
}
else {

    [musicPlayer1 prepareToPlay];
    [musicPlayer1 setVolume:.8];
    [musicPlayer1 setNumberOfLoops:-1]; // -1 means play indefintely
    [musicPlayer1 setDelegate: self];
    [musicPlayer1 play];
}

}

我想用相同的按钮启动和停止AVAudioPlay(musicPlayer1在标题中)。现在，当我触摸按钮时，它不会播放任何内容。请帮忙？

最佳答案

您每次都在创建一个新的AVAudioPlayer实例。您需要保留对某个对象的引用，然后再返回该引用。在您的 View Controller 类中添加一个字段:

@private AVAudioPlayer *currentAudio;

然后在此方法中进行以下更改:

if (currentAudio) {
    [currentAudio stop];
    [currentAudio release];
    currentAudio = nil;
} else {
    // what you already have goes here
}
