因此，我的应用可以选择使用Google登录 . 单击Google提供的按钮后，将打开Web视图并让用户输入其凭据 . 在允许应用访问他们的信息后，应用程序然后签署用户并将SignInViewController更改为TabBarController（他们现在可以相应地进行交互） .
当用户按下“注销”按钮时，他们将按照人们的预期被定向到登录屏幕 . 但奇怪的是，如果用户再次按下谷歌按钮，他们会自动登录，根本不需要进一步的身份验证，也无法删除他们的帐户 . 他们是否有办法清除谷歌帐户凭据以保护用户免遭意外盗窃？
Sign in function:
func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) {
if let error = error {
print(error.localizedDescription)
return
}
let authentication = user.authentication
let credential = FIRGoogleAuthProvider.credentialWithIDToken(authentication.idToken, accessToken: authentication.accessToken)
FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
// ...
SignInViewController().signedIn(user)
}
// ...
}
Sign out function:
func signOutOverride() {
do {
try! FIRAuth.auth()!.signOut()
CredentialState.sharedInstance.signedIn = false
// Set the view to the login screen after signing out
let storyboard = UIStoryboard(name: "SignIn", bundle: nil)
let loginVC = storyboard.instantiateViewControllerWithIdentifier("SignInVC") as! SignInViewController
let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
appDelegate.window?.rootViewController = loginVC
} catch let signOutError as NSError {
print ("Error signing out: \(signOutError)")
}
}
