ios - 现在无法以编程方式在 Facebook 上共享文本 IOS

Question

我无法快速以编程方式在 Facebook 上共享文本。请看我的代码。在这里，

     let facebookPostAction = UIAlertAction(title: "Share on Facebook", style:              UIAlertActionStyle.Default) 

       { (action) -> Void in

        if      SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
            let facebookComposeVC = SLComposeViewController(forServiceType: SLServiceTypeFacebook)

            facebookComposeVC.setInitialText("\(self.noteTextview.text)")

            self.presentViewController(facebookComposeVC, animated: true, completion: nil)
        }
        else {
            self.showAlertMessage("You are not connected to your Facebook account.")
        }

    }

最后这个函数在运行时对我说

facebook share is invalidated

我该怎么办？

Facebook改变了分享政策，所以你需要使用他们的SDK分享。现在开发人员需要安装 FBSDKShareKit.framework，并简单地添加带有上下文信息的按钮。

https://developers.facebook.com/docs/sharing/ios

简单地说，您需要添加 FBSDKShareButton，通过它从 UIButton 扩展的方式，并为其设置上下文数据:

_fbButton = FBSDKShareButton()
...
// setup visual part
// don't need to add target, facebook's sdk decides action
...
// set context data to shareContent button's property
let fbContent = FBSDKShareLinkContent()
fbContent.contentURL = value.contentURL
fbContent.contentTitle = value.contentTitle
fbContent.contentDescription = value.contentDescription
fbContent.imageURL = value.imageURL
_fbButton.shareContent = fbContent

就是这样，Facebook 的分享面板将在点击此按钮后显示包含的数据。
