Question

我无法在swift中以编程方式在Facebook上分享文字。请看我的代码。就是这样，

     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.")
        }

    }

最后这个功能在运行时告诉我

facebook分享无效

我该怎么办？

Answer 1

Facebook已经改变了共享政策，因此您需要使用他们的SDK进行共享。现在开发人员需要安装FBSDKShareKit.framework，以及带有上下文信息的简单添加按钮。

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

简单地说，你需要通过从UIButton扩展的方式添加 FBSDKShareButton ，并将上下文数据设置为它：

_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

全部，Facebook的共享面板将在此按钮内触摸后显示包含的数据。

根据Facebook政策，不允许使用预先填写的文字进行发布。看看https://developers.facebook.com/docs/apps/review/prefill

Answer 3

您可以分享文字。试试这个

    if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
        let fbShare:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
        fbShare.title="share"
        self.presentViewController(fbShare, animated: true, completion: nil)

    } else {
        let alert = UIAlertController(title: "Accounts", message: "Please login to a Facebook account to share.", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
        self.presentViewController(alert, animated: true, completion: nil)
    }

以编程方式在Facebook上共享文本IOS现在不可能
