【问题描述】：

在func filepriavte; func setupGoogleButtons() 处收到错误提示

函数声明的参数列表中应为“（”

import UIKit

import Firebase

import GoogleSignIn

class ViewController: UIViewController, GIDSignInUIDelegate 
    
    override func viewDidLoad() 
        super.viewDidLoad()

        setupGoogleButtons()
    
    
    ****func filepriavte; func setupGoogleButtons()** **
        // Add Google Login Button
        
        let googleButton = GIDSignInButton()
        googleButton.frame = CGReact(x: 60, y: 500, width: view.frame.width - 115,
                                     geight: 50)
        view.addSubview(googleButton)
        
        GIDSignIn.sharedInstance().uiDelegate = self
    
    
    override func didReceiveMemoryWarning() 
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    

【问题讨论】：

****func filepriavte; func setupGoogleButtons()** ** 应该是fileprivate func setupGoogleButtons()

所有的星号是怎么回事？

【参考方案1】：

整个Controller应该是这样的

import UIKit

import Firebase

import GoogleSignIn

class ViewController: UIViewController, GIDSignInUIDelegate 

    override func viewDidLoad() 
        super.viewDidLoad()

        setupGoogleButtons()
    

    priavte func setupGoogleButtons()  // Use private instead of fileprivate
        // Add Google Login Button

        let googleButton = GIDSignInButton()
        googleButton.frame = CGReact(x: 60, y: 500, width: view.frame.width - 115,
                                     geight: 50)
        view.addSubview(googleButton)

        GIDSignIn.sharedInstance().uiDelegate = self
    

    override func didReceiveMemoryWarning() 
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    

希望这会奏效。
