通过Messenger共享对话框共享链接后如何摆脱返回messenger

Question

目前，我的代码是打开分享对话框，通过messenger分享链接：

let invitationLink = NSURL(string:"http://somelink.com")

        if (UIApplication.sharedApplication().canOpenURL(NSURL(string: "fb-messenger-api://")!)){

            let share  = FBSDKMessageDialog()

            share.shareContent = FBSDKShareLinkContent()

            share.delegate = self
            share.shareContent.contentURL = invitationLink

            share.show()
        }[![enter image description here][1]][1]

我也通过我的视图控制器上的FBSDKSharingDelegate处理响应

通过这样做，应用程序打开Messenger，似乎当messenger共享完成或取消时，我仍然有"Back to Messenger“，就像Messenger应用程序是发起人一样……我本以为在关闭共享对话框后不会看到“返回Messenger”按钮。有什么想法吗？

提前谢谢你，

尝试将此行添加到AppDelegate

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool
{
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    return true
}
