ios - imagepickercontroller 的 photoLibrary 中的视频

Question

我试图仅在我的 imagePickerController 中显示视频图 block 。我知道您必须更改媒体类型，我已经这样做了。我想要的只是让它仅显示视频图 block ，而不显示相机胶卷和像您在此处看到的那样的时刻

我只想要如图所示的一个视频图 block 。我不想先点击相机胶卷然后再观看视频。我只想要一个单独的视频图 block ，以明确其中只有视频。

我已经为我的图像选择器添加了 Controller

/// 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"
    }

}

还有为什么我不能更改标题

Answer 1

All I want is for it to show only videos tile, not camera roll and moments like you see here

那就不要使用UIImagePickerController；编写您自己的选择器。如果您使用 UIImagePickerController，您将受到它所提供的限制。它为您提供源类型 .photoLibrary 和 .savedPhotosAlbum ，仅此而已。
