Question

我目前正致力于将照片和视频上传到我的应用。到目前为止，我已完成照片上传，但当我在iPad上访问我的图书馆时，我看不到我的视频或选择它们。谁知道我怎么做到这一点？

到目前为止，这是我的代码：

Class SixthViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate 
{

    @IBOutlet weak var logUd: UIButton!
    @IBOutlet weak var myImageView: UIImageView!
    @IBOutlet weak var vælgFiler: UIButton!
    var SelectedAssets = [PHAsset]()
    var PhotoArray = [UIImage]()
    @IBOutlet weak var upload: UIButton!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        logUd.backgroundColor = UIColor.white
        logUd.layer.cornerRadius = 7
        logUd.setTitleColor(UIColor.black, for: .normal)

        vælgFiler.backgroundColor = UIColor.white
        vælgFiler.layer.cornerRadius = 7
        vælgFiler.setTitleColor(UIColor.black, for: .normal)

        upload.backgroundColor = UIColor.white
        upload.layer.cornerRadius = 7
        upload.setTitleColor(UIColor.black, for: .normal)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func logUd(_ sender: Any) {
        dismiss(animated: true, completion: nil)
    }

    @IBAction func upload(_ sender: Any) {
        //myImageUploadRequest()
    }

    @IBAction func vælgFiler(_ sender: Any) {

        let vc = BSImagePickerViewController()

        self.bs_presentImagePickerController(vc, animated: true,
         select: { (assets: PHAsset) -> Void in

        },deselect: { (asset: PHAsset) -> Void in

        },cancel: {(assets: [PHAsset]) -> Void in

        }, finish: {(assets: [PHAsset]) -> Void in

            for i in 0..<assets.count{
                self.SelectedAssets.append(assets[i])
            }
            self.convertAssetToImages()
        }, completion: nil)
    }

func convertAssetToImages() -> Void {

    if SelectedAssets.count != 0{

        for i in 0..<SelectedAssets.count{

            let manager = PHImageManager.default()
            let option = PHImageRequestOptions()
            var thumbnail = UIImage()
            option.isSynchronous = true

            manager.requestImage(for: SelectedAssets[i], targetSize: CGSize(width: 200, height: 200), contentMode: .aspectFill, options: option, resultHandler: {(result, info)->Void in thumbnail = result!
            })
            let data = UIImageJPEGRepresentation(thumbnail, 0.7)
            let newImage = UIImage(data: data!)
            self.PhotoArray.append(newImage! as UIImage)
        }
        self.myImageView.animationImages = self.PhotoArray
        self.myImageView.animationDuration = 10.0
        self.myImageView.startAnimating()
    }
    print("complete photo array \(self.PhotoArray)")
}

如果您希望BSImagePicker能够显示视频和照片，则必须更改图书馆的来源。

有一个名为PhotosViewController的文件显示照片网格。内部采用initializePhotosDataSource方式过滤掉所有视频，仅显示带有以下内容的照片

fetchOptions.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.image.rawValue)

如果你要从fetchOptions中删除这个谓词，那么图书馆会（我已经测试了这个）显示视频和照片......

将视频文件从库添加到应用程序？
