Question

我正在尝试与Vimeo和Facebook分享视频。我可以从库中做到这一点，但是当我尝试在代码中创建它时，它已经失败了，我已经尝试了这个

  func showSheet() {
        let bundle = NSBundle.mainBundle()
        let videoURL:NSURL = NSURL.fileURLWithPath(self.outputUrl!)!
        //let asset:AVAsset = AVAsset.assetWithURL(videoURL) as AVAsset
        let asset:ALAsset = ALAsset.setVideoAtPath(videoURL)

        //NSString* path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/image.mov"];
        //NSURL *videoURL = [NSURL fileURLWithPath:myFilePath];        
        let objectsToShare = [textToShare, asset]
        //let objectsToShare = [textToShare, videoURL]

        let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
        activityVC.excludedActivityTypes = [UIActivityTypeAddToReadingList]
        self.presentViewController(activityVC, animated: true, completion: nil)

    }

从注释行中可以看出，我尝试传递NSURL，AVAsset和ALAsset，唯一有效的是NSURL。我可以通过iMessage发送它，但它不适用于Facebook。此外，Vimeo和YouTube从未出现在列表中，即使它们在我从照片库触发工作表时出现。我究竟做错了什么？在this page底部的数据网格之后，我应该能够传递资产。

如何使用Swift将视频从UIActivityViewController分享到Vimeo或Facebook
