ios - 如何快速打开电影画廊

Question

我正在尝试在 iPad 上打开电影图库，但出现此错误，而且我不知道为什么。

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Source type must be UIImagePickerControllerSourceTypeCamera'

这是我的代码:

func GaleriaVideo() {
   if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum) {
        println("Galeria Video")

        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        imagePicker.mediaTypes = [kUTTypeMovie]
        imagePicker.allowsEditing = false

        imagePicker.showsCameraControls = false

        imagePicker.modalPresentationStyle = .Custom
        self.presentViewController(self.imagePicker, animated: true, completion: nil)
    }
}

类似的代码适用于我的照片库，但我不知道为什么这不起作用。

你能告诉我我的代码有什么问题，或者我必须搜索什么才能做到这一点吗？几天前我正在尝试这个，但我感到迷失了。

谢谢你，

编辑:

这是我的照片库，它可以正常工作:

    func GaleriaImagen() {

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){
        println("Galeria Imagen")

        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum
        imagePicker.allowsEditing = false

        imagePicker.modalPresentationStyle = .Custom
            self.presentViewController(self.imagePicker, animated: true, completion: nil)

    }
}
func imagePickerControllerDidCancel(picker: UIImagePickerController!) {

    self.dismissViewControllerAnimated(false, completion: nil)
}

func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
    self.dismissViewControllerAnimated(true, completion: nil)
}

试试这个

func GaleriaVideo() {
   if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum) {
        println("Galeria Video")

        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
        imagePicker.mediaTypes = [kUTTypeMovie]
        imagePicker.allowsEditing = false

        imagePicker.showsCameraControls = false

        imagePicker.modalPresentationStyle = .Custom
        self.presentViewController(self.imagePicker, animated: true, completion: nil)
    }
}
