Sharing text on Facebook programatically IOS is not possible now

Question

I cannot able to share text on Facebook programatically in swift. See my code please. Here is it,

     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.")
        }

    }

This function at the end says to me on run

facebook share is invalidated

What should I do with this?

Answer 1

Facebook has changed policy of sharing, so you need to use their SDK for sharing. Now developers need to install FBSDKShareKit.framework, and simple add button with context information.

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

Simple says, you need to add FBSDKShareButton, by the way it extends from UIButton, and set context data to it:

_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

That's all, facebook's share panel will show with included data after touch up inside this button.
