Question

我使用下面的代码使用UIImagePickerController捕获图像和视频。代码工作正常，直到我使用Quickblox启动视频聊天。在我启动并结束视频聊天会话后，用于捕获视频的UIImagePickerController代码停止工作，即不是捕获视频，而是呈现用于拍摄图片的控制器。有什么想法吗？

捕获图片

UIImagePickerController *controller = [[UIImagePickerController alloc] init];
controller.delegate = self;
controller.allowsEditing = NO;
controller.sourceType = UIImagePickerControllerSourceTypeCamera;
controller.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeImage, nil];
[self presentViewController:controller animated:YES completion:nil];

捕获视频

UIImagePickerController *controller = [[UIImagePickerController alloc] init];
controller.sourceType = UIImagePickerControllerSourceTypeCamera;
controller.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
controller.videoQuality = UIImagePickerControllerQualityTypeLow;
controller.videoMaximumDuration = 90;
controller.delegate = self;
[self presentViewController:controller animated:YES completion:nil];

Answer 1

UIImagePickerController还有一个cameraCaptureMode属性。将其设置为所需的模式。

enum {
   UIImagePickerControllerCameraCaptureModePhoto ,
   UIImagePickerControllerCameraCaptureModeVideo 
};
typedef NSUInteger  UIImagePickerControllerCameraCaptureMode;

Answer 2

这似乎是Quickblox的一个错误。根据Quickblox支持，我们应该设置并使用自定义视频捕获会话 - 这可能会解决此问题。我还没试过。
