Swift 2.0 code for Facebook Friend Invite

Question

I've been looking for an equivalent Swift code sample for Facebook friend invite for iOS apps. But I can't find them.

I understand that there is the Objective-C version on Facebook page https://developers.facebook.com/docs/app-invites/ios. However, because I started off with Swift, I find it difficult to translate.

Could someone point me to a source? Thank you.

Answer 1

the code working :

-In viewDidLoad :

let content = FBSDKAppInviteContent()
content.appLinkURL = NSURL(string: "https://test/myapplink")
content.appInvitePreviewImageURL = NSURL(string: "https://test/myapplink")
// Old Way, now depreciated :
//FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
//New way : 
        FBSDKAppInviteDialog.showFromViewController(self, withContent: content, delegate: self)
// Do any additional setup after loading the view.

-In your viewController to conform the protocol delegate:

extension InviteFriendsViewController: FBSDKAppInviteDialogDelegate{
    func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [NSObject : AnyObject]!) {
        //TODO
    }
    func appInviteDialog(appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: NSError!) {
        //TODO
    }
}
