MP3 播放和停止问题？
这段代码工作正常，直到我退出视图并尝试返回它。如果我这样做，停止按钮将不再起作用。离开视图后如何让它继续工作？
-(IBAction)musiconButtonClicked:(id)sender{
NSString *path = [[NSBundle mainBundle] pathForResource:@"NextRevIt" ofType:@"mp3"];
self.audioPlayer = [[AVAudioPlayer alloc ] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[audioPlayer play];
}
-(IBAction)musicoffButtonClicked:(id)sender{
[audioPlayer stop];
}
This code works fine until I exit the view and try to come back into it. If I do this, the stop button no longer works. How do I get it to still work after leaving the view?
-(IBAction)musiconButtonClicked:(id)sender{
NSString *path = [[NSBundle mainBundle] pathForResource:@"NextRevIt" ofType:@"mp3"];
self.audioPlayer = [[AVAudioPlayer alloc ] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[audioPlayer play];
}
-(IBAction)musicoffButtonClicked:(id)sender{
[audioPlayer stop];
}

完成后您需要释放音频播放器。
您还应该在代码中的
play之前使用[audioPlayerprepareToPlay];。You need to release the audio player when you are done with it.
You should also use
[audioPlayer prepareToPlay];beforeplayin your code.
