imagepickercontroller的photoLibrary视频

Question

我正在尝试仅在我的imagePickerController中显示视频磁贴。我知道您必须更改mediaType，而我已经这样做了。我想要的是它只显示视频磁贴，而不是像你在这里看到的相机滚动和时刻

​

​

我只想要一个视频瓦片中看到的这张图片。我不想点击进入摄像机胶片，然后看到视频。我只想要一个单独的视频磁贴，清楚地表明，只有视频在那里。

​

​

我已经为我的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"
    }

}

另外，为什么我不能更改标题

Answer 1

我只想让它只显示视频磁贴，而不是像你在这里看到的相机胶卷和瞬间

那么不要使用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功能的限制。它提供了源类型.photoLibrary和.savedPhotosAlbum，仅此而已。
