有一种方法来保存活动照片到照片库？ [英] Is there a way to save a Live Photo to the Photo Library?

问题描述

我将存储的图片和视频文件传递给：
PHLivePhoto.requestLivePhotoWithResourceFileURLs ，并获得 PHLivePhoto 对象，我可以在 PHLivePhotoView 中显示。但我想知道，一旦我有一个 PHLivePhoto 是有办法保存到照片库吗？

I'm passing stored image and video files to: PHLivePhoto.requestLivePhotoWithResourceFileURLs and getting a PHLivePhoto object that I can display in PHLivePhotoView. But I am wondering, once I have a PHLivePhoto is there a way to save it to the Photo Library?

推荐答案

    NSURL *photoURL = ...;
    NSURL *videoURL = ...;   

    [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
            PHAssetCreationRequest *request = [PHAssetCreationRequest creationRequestForAsset];


            //These types should be inferred from your files

            //PHAssetResourceCreationOptions *photoOptions = [[PHAssetResourceCreationOptions alloc] init];
            //photoOptions.uniformTypeIdentifier = @"public.jpeg";

            //PHAssetResourceCreationOptions *videoOptions = [[PHAssetResourceCreationOptions alloc] init];
            //videoOptions.uniformTypeIdentifier = @"com.apple.quicktime-movie";

            [request addResourceWithType:PHAssetResourceTypePhoto fileURL:photoURL options:nil /*photoOptions*/];
            [request addResourceWithType:PHAssetResourceTypePairedVideo fileURL:videoURL options:nil /*videoOptions*/];

        } completionHandler:^(BOOL success, NSError * _Nullable error) {
            NSLog(@"success? %d, error: %@",success,error);
        }];
