Question

我想使用UIActivityViewController将视频分享到iPhone图库，但它没有显示＆＃34;保存视频＆＃34;选项。我为图像做了同样的事情，它显示了一个名为＆＃34; Save Image＆＃34;这会将图像保存到图库中。我不确定出了什么问题。

NSMutableArray *sharingItems = [NSMutableArray new];
url = [NSURL URLWithString:@"http://abcd.samplevideo/7173355890_4.mp4"];
[sharingItems addObject:url];
 UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:sharingItems applicationActivities:nil];
    [self presentViewController:activityController animated:YES completion:nil];

任何人都可以让我知道出了什么问题吗？

下载易于分享的文件

NSURLRequest * request = [NSURLRequest requestWithURL：url];

[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]  completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {

    NSURL *documentsURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] firstObject];
    NSURL *tempURL = [documentsURL URLByAppendingPathComponent:[url lastPathComponent]];
    [data writeToURL:tempURL atomically:YES];
    [sharingItems addObject:tempURL];
    dispatch_async(dispatch_get_main_queue(), ^{
        [self shareSheetForMedia:sharingItems];
    });
   }];
