照片库中用于图像选择器控制器的视频

Question

我试图仅在imagePickerController中显示视频图块。我了解您必须更改mediaType，而我已经做到了。我想要的是仅显示视频图块，而不显示相机胶卷和您在此处看到的瞬间

我只想要一个视频平铺，如这张图片所示。我不需要点击相机胶卷然后观看视频。我只想要一个单独的视频图块，可以清楚地看到其中只有视频。

我为图像选择器添加了控制器

/// Selector Controller used to pick an image
open class ImagePickerController : UIImagePickerController, TypedRowControllerType, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    /// The row that pushed or presented this controller
    public var row: RowOf<URL>!

    /// A closure to be called when the controller disappears.
    public var onDismissCallback : ((UIViewController) -> ())?

    open override func viewDidLoad() {
        super.viewDidLoad()
        delegate = self
        allowsEditing = (row as? _VideoRow)?.allowEditor ?? false
        mediaTypes = [kUTTypeMovie as String, kUTTypeVideo as String]

    }


    public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        guard let videoURL = info[UIImagePickerControllerMediaURL] as? URL else {
            return
        }

        (row as? _VideoRow)?.videoURL = videoURL
        (row as? _VideoRow)?.value = videoURL
        onDismissCallback?(self)
    }

    open func imagePickerControllerDidCancel(_ picker: UIImagePickerController){
        onDismissCallback?(self)
    }

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

}

为什么我不能更改标题

然后不要使用UIImagePickerController;编写自己的选择器。如果使用UIImagePickerController，则只能使用它提供的功能。它为您提供了源类型.photoLibrary和.savedPhotosAlbum，仅此而已。
