从网络播放mp3

我尝试了以下三种解决方案，但都没有工作。我相信我错过了一些关键点，但不清楚是什么。（仅供参考，我在iPhone设备上尝试以下解决方案，而不是在模拟器。）从网络播放mp3

- (IBAction)actionAVPlayer:(id)sender { 
AVPlayer* player = [[AVPlayer alloc] initWithURL:[NSURL URLWithString:urlTextField.text]]; 
[player play]; 

} 

- (IBAction)actionMemoryBuffer1:(id)sender { 

    NSError *error; 
    NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlTextField.text]]; 

    AVAudioPlayer* audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error]; 
    audioPlayer.numberOfLoops = -1; 
    audioPlayer.delegate = self; 
    audioPlayer.volume = 1.0f; 
    [audioPlayer prepareToPlay]; 

    if (audioPlayer == nil) 
    NSLog(@"%@", [error description]); 
    else 
    [audioPlayer play]; 
} 


- (IBAction)actionMemoryBuffer2:(id)sender { 

    NSURLRequest* request = [ NSURLRequest requestWithURL: [NSURL URLWithString:urlTextField.text] ]; 
    NSError *requestError; 
    NSURLResponse *urlResponse = nil; 

    NSData *_objectData = [ NSURLConnection sendSynchronousRequest:request returningResponse: &urlResponse error: &requestError]; 

    NSError *error; 
    AVAudioPlayer* audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error]; 
    audioPlayer.numberOfLoops = -1; 
    audioPlayer.delegate = self; 
    audioPlayer.volume = 1.0f; 
    [audioPlayer prepareToPlay]; 

    if (audioPlayer == nil) 
    NSLog(@"%@", [error description]); 
    else 
    [audioPlayer play]; 
}

任何帮助深表感谢。

很多后解决问题和花费时间，最后解决问题。它变得非常非常简单。变量范围。在我所有的三种方法中，我在方法中定义了玩家实例变量，只要方法执行完成，玩家变量引用计数就被设置为ZERO（通过ARC）。所以我定义了一个类级别的变量，赋予了它的实例变量并且一切正常。 – Shas 2012-08-13 10:53:27

尝试使用MPMoviePlayerController。首先，您需要导入MediaPlayer框架。那么它的，因为这很容易：

MPMoviePlayerController *myAudioPlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:urlTextField.text]]; 
[myAudioPlayer play];
