ios - 仅在 UIImagePickerController 中显示视频

Question

我正在使用以下代码来呈现 UIImagePickerController。对于某些特定场景，我只需要视频。并使用以下代码。

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.sourceType = sourceType;
imagePickerController.delegate = self;
imagePickerController.allowsEditing=NO;

imagePickerController.mediaTypes=[[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie,nil];

[self presentViewController:imagePickerController animated:YES completion:nil];

但它在表格 View 中显示相机胶卷、我的照片流和视频。如果我打开任何文件夹，内容只是视频。我只想要视频我怎么能做到这一点。还有标题照片，我也想改变它到视频。

Answer 1

swift 3 更新:

let videoPicker = UIImagePickerController()  
videoPicker.delegate = self
videoPicker.sourceType = .photoLibrary
videoPicker.mediaTypes = [kUTTypeMovie as String]
self.present(videoPicker, animated: true, completion: nil)

导入 导入 MobileCoreServices 并在顶部添加委托(delegate) UIImagePickerControllerDelegate 和 UINavigationControllerDelegate

呈现的模式将具有“照片”标题。您可以这样更改它:

func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        viewController.navigationItem.title = "Choose Video"
}
