AVFoundation iOS 5

我在应用商店中运行的应用使用自 iOS5 更新以来无法使用的 mp3 和视频文件。

我已经安装了 xcode 4.2 并且... 当我在 iPhone 5 模拟器或设备中进行测试时，出现以下错误（对于音频或视频文件）：

Error loading 
System/Library/Extensions/AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn:  
dlopen(/System/Library/Extensions/AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn, 262):

Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.0.sdk/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation
in /System/Library/Frameworks/Security.framework/Versions/A/Security

当我在 iPhone 4.3 模拟器<中尝试此操作时/strong> 或设备它不会崩溃 ..

我已经清理并重新导入涉及的框架，但这似乎是那种错误

注意：我的应用程序不使用任何安全性。

你能帮忙吗？

My apps runing on the appstore are using mp3 and video files that don't work since iOS5 update.

I've installed xcode 4.2 and...
When I test in the iPhone 5 Simulator or device I get the following error (for audio or video files):

Error loading 
System/Library/Extensions/AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn:  
dlopen(/System/Library/Extensions/AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn, 262):

in /System/Library/Frameworks/Security.framework/Versions/A/Security

When I try this in the iPhone 4.3 simulator or device it does not crash ..

I've cleaned and re import the frameworks involved but it seems to be that kind of error

Note: My apps don't use any security.

Could you help?

我刚刚在这里找到了答案。

如果您的应用程序在此处崩溃，请禁用 XCode 4 Breakpoints Tab 中的所有异常。可能是SDK的bug。

尝试让你的球员成为保留财产。我经历了同样的事情，因为我在本地声明了我的播放器，所以我认为一旦我声明播放器的方法超出范围，ARC 就会保留。

让玩家成为保留属性

@property (strong)AVAudioPlayer *player;

记住设置委托（self.player.delegate = self）并使用委托的方法进行清理：

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)playedSuccessfully {
    self.player = nil;
}

Try to make your player a retained property. I experienced the same and because I declared my player locally I think ARC retained as soon as the method in which I declared the player ran out of scope.

Make player a retained property

@property (strong)AVAudioPlayer *player;

Remember to set the delegate (self.player.delegate = self) and use the delegate's methods to clean up:

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)playedSuccessfully {
    self.player = nil;
}

我找到了解决方案：NSURL 而不是 NSString：

NSURL *chemin = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/MySound.wav", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
AVAudioPlayer* mySound = [[AVAudioPlayer alloc] initWithContentsOfURL:chemin error:&error];
mySound.delegate = self;
[chemin release];
[mySound Play];

I found the solution: NSURL instead of NSString:

NSURL *chemin = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/MySound.wav", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
AVAudioPlayer* mySound = [[AVAudioPlayer alloc] initWithContentsOfURL:chemin error:&error];
mySound.delegate = self;
[chemin release];
[mySound Play];
