Question

当我搜索它时，我有一个非常常见的问题，但我无法得到正确答案。

这是我努力播放音频文件的代码片段。

在viewDidLoad方法中

：

    NSURL *buttonSound = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/button4.wav", [[NSBundle mainBundle] resourcePath]]];

    NSURL *correctSound = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/key_drop1.wav", [[NSBundle mainBundle] resourcePath]]];

    NSURL *wrongSound = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/sound8.mp3", [[NSBundle mainBundle] resourcePath]]];


    NSError *error;

    ButtonPressedSound = [[AVAudioPlayer alloc] initWithContentsOfURL:buttonSound error:&error];
    ButtonPressedSound.numberOfLoops = 0;


    correctAnsweredSound = [[AVAudioPlayer alloc] initWithContentsOfURL:correctSound error:&error];
    correctAnsweredSound.numberOfLoops = 0;


    wrongAnsweredSound = [[AVAudioPlayer alloc] initWithContentsOfURL:wrongSound error:&error];
    wrongAnsweredSound.numberOfLoops = 0;

在IBAction中按下按钮m，以这种方式调用“播放”。

                [ButtonPressedSound play];

            [self performSelector:@selector(stop) withObject:nil afterDelay:0.50];

                [correctAnsweredSound play];

                [self performSelector:@selector(stop) withObject:nil afterDelay:0.50];

                [wrongAnsweredSound play];

                [self performSelector:@selector(stop) withObject:nil afterDelay:1.0];

我的播放和停止方法是：

-(IBAction)play
{

self.ButtonPressedSound.currentTime = 0;
[self.ButtonPressedSound play];

self.correctAnsweredSound.currentTime = 0;
[self.correctAnsweredSound play];

self.wrongAnsweredSound.currentTime = 0;
[self.wrongAnsweredSound play];


}

-(IBAction)stop
{
[self.ButtonPressedSound stop];
[self.correctAnsweredSound stop];
[self.wrongAnsweredSound stop];

}

到目前为止我做了什么......

我搜索过这些链接但没有得到我的代码的答案。

AVAudioPlayer only plays in simulator but not device why?! (iPhone-SDK)

mp3 Sounds Playing on simulator but not on Device (Audio BeatBox)

...........

我检查了所有名字，没有任何拼写错误。

不知道哪里出错了，请帮助!!!

之前我遇到过类似的问题，但这个解决方案只是一个随机的猜测，当时对我有用。

在真正的iPhone上，文件路径区分大小写。在模拟器上，它们不是。所以我会检查以确保您的文件路径完全正确，包括大小写。

.mp3和.wav文件适用于模拟器，但不适用于设备
