Question

我正在尝试使用以下代码将GIF从URL保存到相机胶卷：

var image = UIImage(data: NSData(contentsOfURL: self.imageView.sd_imageURL())!)
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)

但保存后，GIF成为静止图像，任何人都可以帮助我吗？谢谢！

Answer 1

试试这个：

import AssetsLibrary


let image = NSData(contentsOfURL: url)

ALAssetsLibrary().writeImageDataToSavedPhotosAlbum(image, metadata: nil, completionBlock: { (assetURL: NSURL!, error: NSError!) -> Void in
        print(assetURL)
})

Answer 2

您可以通过PHPhotoLibrary保存GIF

    PHPhotoLibrary.shared().performChanges({
        let request = PHAssetCreationRequest.forAsset()
        request.addResource(with: .photo, fileURL: YOUR_GIF_URL, options: nil)
    }) { (success, error) in
        if let error = error {
            completion(.failure(error))
        } else {
            completion(.success(true))
        }
    }
