iOS Swift - 来自图书馆/画廊的视频选择器

Question

我正在尝试实现一项功能，可以从 iPhone 的图库中选择视频。

这是我的功能：

func openVideoGallery()
    {
        let picker = UIImagePickerController()
        picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
        picker.sourceType = .savedPhotosAlbum
        picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .savedPhotosAlbum)!
        picker.mediaTypes = ["public.movie"]

        picker.allowsEditing = false
        present(picker, animated: true, completion: nil)
    }

这是我的问题：

• 我想知道使用UIImagePickerController从图库中获取视频是否正确？
• 如何获得选择的视频路径？

谢谢你的帮助^^

Answer 1

1-是的

2-实现

func imagePickerController(_ picker: UIImagePickerController, 
  didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

    if let asset =  info[UIImagePickerController.InfoKey.phAsset] as? PHAsset {

        asset.getURL { (tempPath) in 

        }

    }
    else  if let media =  info[UIImagePickerController.InfoKey.mediaURL] as? URL {

    }
    else
        if let ref =  info[UIImagePickerController.InfoKey.referenceURL] as? URL {

    }
}

改变这个

picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate

到

picker.delegate = self  

并使vc符合

class VCName: UIViewController,UIImagePickerControllerDelegate & UINavigationControllerDelegate {
