調用默認的委託執行

Question

我執行GoogleSignInDelegate爲authentication.In，我已經實現了GoogleSignIn代表method.I要添加UIActivityIndi​​cator在它與同現有implementation.Any想法的方法之一哪有我這樣做？

在我的註冊控制器中，我實現了委託的方法。

// MARK: GIDSignInDelegates. 

    func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) { 

     showProgressBarIndicator() 

     if (error == nil) { 

      let params = [ 
       "access_token" : user.authentication.accessToken, 
       "email"   : user.profile.email, 
       "name"   : user.profile.name, 
       "photoUrl"  : user.profile.imageURLWithDimension(100).absoluteString, 
       "profile_url" : user.profile.imageURLWithDimension(100).absoluteString, 
       "provider"  : Provider.GooglePlus.rawValue, 
       "provider_id" : user.authentication.clientID 
      ] 

      AFWrapper.requestPOSTURL(BaseUrl + ApiMethod.SignUp.rawValue, params: params, 

       success: {(JSONResponse) -> Void in 
        self.saveDataToDisk(JSONResponse) 
       }, 

       failure: { (error) -> Void in 
        dispatch_async(dispatch_get_main_queue(), { 
         self.removeProgressBarIndicator() 
         JLToast.makeText("Connection Error!").show() 
        }) 
       } 
      ) 
     } else { 
      dispatch_async(dispatch_get_main_queue(), { 
       self.removeProgressBarIndicator() 
       JLToast.makeText("Error in getting data from Google!").show() 
      }) 

     } 
    } 

和IM我的基本控制器我有以下方法。

func showProgressBarIndicator() { 

     container.frame = self.view.frame 
     container.center = view.center 
     container.backgroundColor = UIColor(colorLiteralRed: 255.0, green: 255.0, blue: 255.0, alpha: 0.7) 

     let loadingView: UIView = UIView() 
     loadingView.frame = CGRectMake(0, 0, 80, 80) 
     loadingView.center = view.center 
     loadingView.backgroundColor = UIColor(colorLiteralRed: 0.0, green: 0.0, blue: 0.0, alpha: 0.7) 
     loadingView.clipsToBounds = true 
     loadingView.layer.cornerRadius = 10 

     let activityIndicator: UIActivityIndicatorView = UIActivityIndicatorView() 
     activityIndicator.frame = CGRectMake(0.0, 0.0, 40.0, 40.0); 
     activityIndicator.activityIndicatorViewStyle = 
      UIActivityIndicatorViewStyle.WhiteLarge 
     activityIndicator.center = CGPointMake(loadingView.frame.size.width/2, 
               loadingView.frame.size.height/2); 
     activityIndicator.startAnimating() 
     loadingView.addSubview(activityIndicator) 

     container.addSubview(loadingView) 
     self.view.addSubview(container) 
    } 


func removeProgressBarIndicator() { 
     if !container.isDescendantOfView(self.view) { 
      self.container.removeFromSuperview() 
     } 
    }
