Answer 1

Unfortunately with the iOS 11 update the social network services (Facebook, Twitter, Vimeo, and Flickr), which used to have single sign-on for systemwide integration have been removed.

Instead to use this snippet for iOS 10 and before :

let viewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
viewController.add(imageView.image!)
viewController.add(URL(string: "http://www.example.com/"))
viewController.setInitialText("Text to post!")

self.present(viewController!, animated: true, completion: nil)

You can post on Facebook using the FBSDKGraphRequest .

First create from Facebook Developer Console your app. After that, setup your Xcode project (following the instructions here: https://developers.facebook.com/docs/ios/getting-started/ ).

The user need to be logged before post:

    let login: FBSDKLoginManager = FBSDKLoginManager()
        login.logIn(withPublishPermissions: ["publish_actions"], from: self) { (result, error) in

            if (error != nil) {
                print("publish_actions: \(error!)")
            } else if (result?.isCancelled)! {
                print("publish_actions: Canceled")
            } else if (result?.grantedPermissions.contains("publish_actions"))! {
                print("publish_actions: permissions granted: \(String(describing: result?.token.tokenString))")

                UserDefaults.standard.set(result?.token.tokenString, forKey: "facebook_token")

            }

        }

After the logging save the token and use it to post a message through FBSDKGraphRequest:

FBSDKGraphRequest.init(graphPath: "me/feed",
                           parameters: ["message": "text to post on Facebook"],
                           tokenString: "token",
                           version: "v2.10",
                           httpMethod: "POST").start(completionHandler: { (connection, result, error) -> Void in
                            if let error = error {
                                print("Error: \(error)")
                            } else {
                                print("Posted successfully!")
                            }
                           })

Hope this help.

This problem for iOS 11 with Facebook Share (in my case, FBSDKShareDialog in Objective-c) is fixed by upgrading to the latest Facebook API frameworks. Via pods, that is currently as follows:

Podfile

  pod 'FBSDKCoreKit', '~> 4.27.0'
  pod 'FBSDKLoginKit', '~> 4.27.0'
  pod 'FBSDKShareKit', '~> 4.27.0'

From a command prompt, Using "pod search " will show the latest version of the pod. For example, pod search FBSDKShareKit
