Question

我尝试使用JPG文件和MOV文件制作实时照片。就像这样：

   CGSize targetSize = CGSizeZero;
    PHImageContentMode contentMode = PHImageContentModeDefault;


    __weak NSURL *videoUrl;
    __weak NSURL *photoUrl;

//         Call private API to create the live photo
            self.livePhotoView.livePhoto = nil;
            self.livePhoto = nil;
            self.livePhoto = [[PHLivePhoto alloc] init];
            SEL initWithImageURLvideoURL = NSSelectorFromString(@"_initWithImageURL:videoURL:targetSize:contentMode:");
            if ([self.livePhoto respondsToSelector:initWithImageURLvideoURL]) {
                NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[self.livePhoto methodSignatureForSelector:initWithImageURLvideoURL]];
                [invocation setSelector:initWithImageURLvideoURL];
                [invocation setTarget:self.livePhoto];
                [invocation setArgument:&(photoURL) atIndex:2];
                [invocation setArgument:&(videoUrl) atIndex:3];
                [invocation setArgument:&(targetSize) atIndex:4];
                [invocation setArgument:&(contentMode) atIndex:5];
                [invocation invoke];
            }

            // Set the live photo
            self.livePhotoView.livePhoto = self.livePhoto;

最后，我获得了实时照片并在livePhotoView中显示。然后我尝试保存或分享它。我使用Class UIActivityViewController.Like this：

  if (self.livePhoto) {

    UIActivityViewController *activityViewController =
    [[UIActivityViewController alloc] initWithActivityItems:@[self.livePhotoView.livePhoto]
                                      applicationActivities:nil];
    [self presentViewController:activityViewController
                       animated:YES
                     completion:^{
                         // ...
                     }];


}

当我分享实时照片时，我分享的只是静止图像。当我选择保存实时照片时，我无法在相册中找到任何内容。我在很多地方搜索。我只是在这里找到一些信息https://github.com/genadyo/LivePhotoDemo/issues/3。但它并没有解决我的问题。

我发现一个应用程序可以在AppStore中执行。但我无法理解它是如何工作的。https://itunes.apple.com/cn/app/livemaker-free-for-live-photo/id1053967828?mt=8

如何在相册中保存自制的实时照片？
