Facebook share button on iOS 9 opens browser instead of Facebook’s own application

Question

My application uses FBSDKShareButtonone that launches a pop-up window from its own Facebook application on iOS 8. However, on iOS 9 it launches a browser window, although I followed all the instructions for supporting iOS 9 here and added the necessary one LSApplicationQueriesSchemes(and recompiled for iOS 9).

I continue to read that it is “by design” that the facebook login opens a browser instead of its own application on iOS 9, but there is no information on why / whether the sharing button should launch its own application. It appears that the FBSDKShareDialognative application ( ) dialog does indeed launch its own application, but I would like it if I hadn't used my own button.

And the secondary question is: if I use my own button and run FBSDKShareDialog, I get the following errors in the log (although the actual sharing works fine). Why?

-canOpenURL: failed URL: "fbapi20150629: ///" - error: "This application is not allowed to request for the fbapi20150629 schema"

plugin com.apple.share.Facebook.post is invalid

I use the latest SDK for Facebook (v4.6), so a link to the URL scheme is not needed. I am compiling with Xcode 7.0.1.

I believe the problem is with FBSDKShareButton creating FBSDKShareDialog without ViewController. Thus, without VC, he reverts to using the Safari view for sharing. :( You can see this behavior in the FB SDK source here:

https://github.com/facebook/facebook-ios-sdk/blob/fe777bd7a8b335c5780e2ee160d81719e132e76c/FBSDKShareKit/FBSDKShareKit/FBSDKShareButton.m

FBSDKShareButton, , sharecheet ( ) FBSDKShareButton:

public class EventShareButton: FBSDKShareButton {
    func _share(sender: AnyObject) {
        FBSDKShareDialog.showFromViewController(parentViewController(), withContent: shareContent, delegate: nil)
    }
}
