【中文标题】.mp3 和 .wav 文件适用于模拟器，但不适用于设备【英文标题】：.mp3 and .wav files works on simulator, but not on device 【发布时间】：2011-10-04 06:10:54 【问题描述】：

我在搜索时遇到了非常常见的问题，但无法为我找到正确的答案。

这是我正在努力播放音频文件的一段代码。

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;

在按下按钮的IBAction中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......

我已经搜索了这些链接，但没有得到我的代码的答案。

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

...........

我已经检查了所有的名字 n 没有任何拼写错误。

不知道哪里出错了，请帮忙！！！

我以前也遇到过类似的问题，但这个解决方案只是我当时的一个随机猜测。

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。
