UIImagePickerController抛出错误：185：创建聚合音频设备时出错：尝试选择视频时“什么” [英] UIImagePickerController throws ERROR: 185: Error creating aggregate audio device: 'what' when trying to select video

问题描述

当我尝试使用UIImagePickerController从XCode 5的iOS模拟器中的相机胶卷中选择视频时，我得到上述错误。这是输出：

when i try to use UIImagePickerController to select a video from camera roll in the iOS-Simulator of XCode 5, i get the aforementioned error. this is the output:

2013-11-02 21:28:44.788 Imagepicker[89146:1403] 21:28:44.788 ERROR:     185: Error creating aggregate audio device: 'what'

我的代码是：

imagePicker = [[UIImagePickerController alloc] init];
imagePicker.mediaTypes =[[NSArray alloc] initWithObjects: (NSString *) kUTTypeMovie,kUTTypeVideo,kUTTypeImage, nil];
[imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[imagePicker setDelegate:self];
[self presentViewController:imagePicker animated:YES completion:nil];

图像选择器显示，显示取消预览，播放和选择按钮以及显示的对话框操作无法完成。按确定（唯一按钮）后，预览会冻结。

the image picker shows up, shows a preview with cancel, play and choose button and a dialog that says "The operation could not be completed". after pressing "OK" (the only button), the preview freezes.

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

永远不会被调用。这一切都适用于图像。

never gets called. it all works fine with images.

推荐答案

我对最新的工具链有完全相同的问题，但以下修复了它对我来说;

I've had exactly the same problem with the latest toolchain, but the following fixed it for me;

1. 在模拟器硬件菜单上，选择电视输出 - > 640x480。

1. On the simulator Hardware menu, select TV Out->640x480.

尝试从Xcode启动您的应用程序，它可能会因跳板错误而失败。

Attempt to launch your app from Xcode, it may fail with a springboard error.

在模拟器硬件菜单上，选择电视输出 - >已禁用。

On the simulator Hardware menu, select TV Out->Disabled.

之后，ImagePickerController现在应按预期工作。

After that the ImagePickerController should now work as expected.
