实例成员“个人资料”不能在“GIDGoogleUser”类型上使用

Question

我正在观看 YouTube 上有关消息应用程序的教程。该教程很旧，并且谷歌 SDK 已更新，这使得我的代码充满了错误。几天来我一直在尝试修复它，甚至发现其他人的更新代码显示了如何做到这一点，但我的代码仍然有错误。我是编码新手，不知道如何让我的 Google 登录按钮正常工作。我跳过了其他代码，只添加了登录视图控制器上的谷歌登录按钮的代码。

class LoginViewController: UIViewController {

// More code for login options

   private let googleLoginButton: GIDSignInButton = {
        let button = GIDSignInButton()
        button.style = GIDSignInButtonStyle.wide
        button.colorScheme = GIDSignInButtonColorScheme.dark
        return button

 override func viewDidLoad() {
        super.viewDidLoad()

 googleLoginButton.addTarget(self,
                                    action: #selector(googleButtonTapped),
                                    for: .touchUpInside)

        scrollView.addSubview(googleLoginButton)

googleLoginButton.frame = CGRect(x: 30,
                                         y: facebookLoginButton.bottom+10,
                                         width: scrollView.width-60,
                                         height: 52)

• 查找谷歌文档
• 查找苹果文档
• 修改后网上查各种错误，又弹出新的错误。

“GIDGoogleUser”类型的值没有成员“身份验证”

Answer 1

我相信这里有一个误解。根据 Google Signin 文档，

GoogleAuthProvider

需要

idToken

和

accessToken.tokenString

。应该是：

GIDSignIn.sharedInstance.signIn(withPresenting: self) { result, error in
    ...
    guard let user = result?.user else {
        return
    }

    guard let user = result?.user,
          let idToken = user.idToken?.tokenString else {
        return    
    }
    ...
    let credential = GoogleAuthProvider.credential(withIDToken: idToken,
                                                   accessToken: user.accessToken.tokenString)
    ...
}
