Swift facebook SDK取消分享对话框

Question

当我点击取消或分享按钮时，对话框总是将我带到我的Facebook页面。当我点击取消或分享按钮时，有没有办法让它返回我的应用程序。非常感谢，抱歉我的英语不好。

这是我的代码

import UIKit
import Parse
import Bolts

class FacebookController: UIViewController {

let UserDef: NSUserDefaults = NSUserDefaults()

func FBsharelink() {

    var playerTime = UserDef.valueForKey("TimeOfPlayer") as! Int
    var playerScore = UserDef.valueForKey("PlayerScore") as! Int

    let content : FBSDKShareLinkContent = FBSDKShareLinkContent()
    content.contentURL = NSURL(string: "https://www.facebook.com/CityDefender")
    content.contentTitle = "I have \(playerScore) scores in \(playerTime) seconds. Come and beat me !"
    content.contentDescription = "City Defender News"

    FBSDKShareDialog.showFromViewController(self, withContent: content, delegate: nil)

}   
}
