Question

按下uibutton时，我正试图播放声音..

这是我的代码

-(IBAction) playSound:(id)sender{

    NSString *path = [[NSBundle mainBundle] pathForResource:@"SQUEEK" ofType:@"wav"];
    AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

    theAudio.delegate=self;
    [theAudio play];

}

这是按下按钮时的输出

IBAction与UIButton连接，具有内置功能，我也添加了avfoundation框架。

任何帮助将不胜感激。

在询问相同的问题之前，您只需要在Stack Overflow中进行更多搜索。无论如何检查以下问题并尝试解决方案。

Sound not playing with AVAudioPlayer

Supported Audio file formats in iPhone

检查您的音频格式可能有问题，或者您的“theAudio”实例应该被取消分配。

尝试这样并打印错误......

NSError *error;
audioPlayer = [[AVAudioPlayer alloc]
                 initWithContentsOfURL:url
                 error:&error];
if (error)
{
        NSLog(@"Error in audioPlayer: %@", 
              [error localizedDescription]);
} else {
        audioPlayer.delegate = self;
        [audioPlayer prepareToPlay];
}
