我用AVAudioRecorder它来录制,它在iOS 4设备上运行良好,但昨天我们发现录制在iOS5上被破坏了.使用iPhone 5模拟器我收到以下错误:

2011-08-02 11:09:03.586 Moodle [7832:10103]加载/System/Library/Extensions/AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn:dlopen(/ System/Library /扩展/ AudioIPCDriver.kext/Contents/Resources/AudioIPCPlugIn.bundle/Contents/MacOS/AudioIPCPlugIn,262):找不到符号:___ CFObjCIsCollectable

你知道这个错误来自何处以及如何解决这个问题？

我在iOS 6模拟器上运行我的应用程序(音乐和视频流播放器)时遇到了麻烦.

当我开始播放音乐时,它崩溃,在此主题上显示错误:com.apple.coremedia.networkbuffering

这个日志信息:

我正在使用基于http的流的MPMoviePlayerController,它在iOS 4或iOS 5上运行良好

关于如何修复它的任何想法？

我正在开发一个iPhone应用程序,到目前为止一切正常.我可以在模拟器中构建和启动应用程序.但是,当我现在用仪器启动应用程序时,我得到了错误:

Dyld Error Message:
Symbol not found: _CFXMLNodeGetInfoPtr
Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security
Expected in: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.0.sdk/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation

我用谷歌搜索,但没有找到解决方案.

希望有人可以帮助我.谢谢

当我尝试播放任何视频时,我的MPMoviePlayerController崩溃了.

这只发生在模拟器上,在设备上正常工作.

错误如下:

我正在尝试播放MP3,通过AVAudioPlayer它我认为相当简单.不幸的是,它并没有完全奏效.这就是我所做的一切:

• 为了测试,我在Xcode中创建了一个新的iOS应用程序(Single View).

• 我加入了AVFoundation框架到项目中,以及在#import <AVFoundation/AVFoundation.h>对ViewController.m

• 我在应用'文档'文件夹中添加了一个MP3文件.

• 我改为ViewControllers viewDidLoad:以下内容:

码:

- (void)viewDidLoad
{
    [super viewDidLoad];        

    NSString* recorderFilePath = [NSString stringWithFormat:@"%@/MySound.mp3", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]];    

    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:recorderFilePath] error:nil];
    audioPlayer.numberOfLoops = 1;

    [audioPlayer play];

    //[NSThread sleepForTimeInterval:20];
}

不幸的是,音频在开始播放后显然会立即停止.如果我取消注释sleepForTimeInterval它会播放20秒并在之后停止.只有在使用ARC进行编译时才会出现此问题,否则,它会完美无缺地运行.

今天我在xcode上工作,当这个错误出现在应用程序的启动时,我的应用程序出了什么问题？

我想知道是否可以使用iPhone SDK播放Ogg Vorbis音频文件,或者是否存在允许此操作的库或框架.

我读过一些关于OpenAL的内容,但我没有找到任何教程......任何人都可以帮助我吗？

我正在尝试使用MPMoviePlayer播放一部简单的电影,我在控制台中不断收到此错误(但是电影正在播放):我的xcode版本是4.3.1.
