ios - UISaveVideoAtPathToSavedPhotos相册输出

当我使用 UISaveVideoAtPathToSavedPhotosAlbum 将视频保存到“相册”中时，如何以 asset-library://asset/asset.mov .... 格式检索它的新 Assets URL。

//outputURL.path is : file:///private/var/mobile/Applications/4535724C-7ABD-4F00-A363-9A62022F8EB0/tmp/trim.E8CD7632-7C52-4EA4-A462-8C5131B214AA.MOV.exp.mov

UISaveVideoAtPathToSavedPhotosAlbum(outputURL.path, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);

最佳答案

除了UISaveVideoAtPathToSavedPhotosAlbum之外，您还可以使用-[ALAssetsLibrary writeVideoAtPathToSavedPhotosAlbum:(NSURL *)videoPathURL completionBlock (ALAssetsLibraryWriteVideoCompletionBlock)completionBlock]方法(Apple Documentation here)

例如:

ALAssetsLibrary* library = [[ALAssetsLibrary alloc] init];
[library writeVideoAtPathToSavedPhotosAlbum:videoPathURL
                           completionBlock:^(NSURL *assetURL, NSError *error)
{
    /* process assetURL */
}];

重要说明:处理ALAssetsLibrary时要记住的重要一点是，assetURL仅在ALAssetsLibrary实例的生存期内有效。因此，请确保您拥有对库的引用，直到完成处理assetURL和任何关联的ALAsset为止。
