【问题描述】：

我正在使用 UIActivityViewController 来分享图像。 Facebook最近的变化之后。我可以单独分享图片和网址，但我无法同时分享图片和网址。相同的代码适用于 Mail、Twitter 等，但不确定 Facebook 缺少什么。

func shareImage() 
    var myWebsite = NSURL(string:"http://www.google.com/")
    var img: UIImage = currentPhoto!
    var shareItems:Array = [img, myWebsite]
    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
    self.presentViewController(activityViewController, animated: true, completion: nil)

【参考方案1】：

我已经为 swift 2.0 修改了你的代码：

@IBAction func shareButtonPressed(sender: AnyObject) 

    let myWebsite = NSURL(string:"http://www.google.com/")
    let img: UIImage = image!

    guard let url = myWebsite else 
        print("nothing found")
        return
    

    let shareItems:Array = [img, url]
    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
    self.presentViewController(activityViewController, animated: true, completion: nil)

它正在发布带有 URL 的图片。

此代码的结果：

【讨论】：

您的 Facebook 原生应用版本？

我也有，它工作正常。尝试用另一台设备发帖。

对不起哥们，我不知道为什么它不起作用。如果有人知道这个问题，请等待另一个答案。

不，您不能这样做，因为预定义的文本将被忽略。

正如我所说，你不能添加文本.. :)

【参考方案2】：

SWIFT 3

    let myWebsite = NSURL(string: visitedlink)

    let img: UIImage = UIImage(named:"Logo")!

    guard let url = myWebsite else 
        print("nothing found")
        return
    

    let shareItems:Array = [img,url]
    let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
    activityViewController.excludedActivityTypes = [UIActivityType.print, UIActivityType.postToWeibo, UIActivityType.copyToPasteboard, UIActivityType.addToReadingList, UIActivityType.postToVimeo]
    self.present(activityViewController, animated: true, completion: nil)

【讨论】：

我试图在 Facebook 上发布图片，但没有发布。只能分享 URL。我们不能使用 UIActivityViewController 在 Facebook 上分享图像/视频吗？

最近你不能用自己的SDK吗:(@AnandGautam

正确@Safad Funy，但是我们可以使用SLComposeViewController在Facebook上分享图片，但需要使用FB SDK进行视频分享。

【参考方案3】：

这是我的解决方案。实现UIActivityItemSource 协议。支持文字、网址和图片。

func doShare() 
    let viewController = UIActivityViewController(activityItems: ["ScreenSort for ios.", URL.init(string: "https://itunes.apple.com/app/id1170886809")!], applicationActivities: nil)
    viewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash
    self.present(viewController, animated: true, completion: nil)


extension YourViewController: UIActivityItemSource 
    func activityViewControllerPlaceholderItem(_ activityViewController: UIActivityViewController) -> Any 
        return ""
    

    func activityViewController(_ activityViewController: UIActivityViewController, itemForActivityType activityType: UIActivityType) -> Any? 
        return URL.init(string: "https://itunes.apple.com/app/id1170886809")!
    

    func activityViewController(_ activityViewController: UIActivityViewController, subjectForActivityType activityType: UIActivityType?) -> String 
        return "ScreenSort for iOS: https://itunes.apple.com/app/id1170886809"
    

    func activityViewController(_ activityViewController: UIActivityViewController, thumbnailImageForActivityType activityType: UIActivityType?, suggestedSize size: CGSize) -> UIImage? 
        return nil
    

【参考方案4】：

分享图片和文字

        let imgShare : UIImage = UIImage(named: "store")!
        let textToShare = "Image form My app."

        let objectsToShare = [textToShare, imgShare]
        let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

        activityVC.popoverPresentationController?.sourceView = sender
        self.presentViewController(activityVC, animated: true, completion: nil)
