如何通过iOS上的Google登录功能解决“用户取消了登录流程."? [英] How to fix `The user canceled the sign-in flow.` with Sign In with Google on iOS?

问题描述

我正在使用iOS Firebase SDK集成Google登录.当用户点击GIDSignIn按钮时，应用程序会显示一个警报，其中显示"MyAPP" want to use Google.com for Sign in，但是该警报很快就会消失.我在didSignInFor user: GIDGoogleUser方法中遇到的错误如下:

I am integrating Sign in with Google with iOS Firebase SDK. When a user taps on the GIDSignIn button, the app shows an alert showing "MyAPP" want to use Google.com for Sign in, but the alert dismisses quickly. The error I get in the didSignInFor user: GIDGoogleUser method as follows:

2019-02-21 16:54:13.104279+0530 MyApp[18743:185089] [Warning] Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior (<SFAuthenticationViewController: 0x7fa327945800>)
[DEBUG] Google sign-in error: Error Domain=com.google.GIDSignIn Code=-5 "The user canceled the sign-in flow." UserInfo={NSLocalizedDescription=The user canceled the sign-in flow.}

我已遵循在iOS上使用Google登录进行身份验证文档.

我还尝试在在iOS 9上尝试调用canOpenURL的Google登录崩溃崩溃的答案，但事实并非如此.工作.

I also tried the answer at Google Sign-In crashes on iOS 9 attempting to call canOpenURL, but it is not working.

AppDelegate也实现了GIDSignInUIDelegate.

如果我将按钮从 GIDSignInButton更改为UIButton ，它会起作用，但是样式会丢失.

If I change the button from GIDSignInButton to UIButton, it works, but the style is lost.

推荐答案

我之前也遇到过这个问题. GIDSignInButton对象不需要代码或链接@IBAction中的addTarget. GIDSignInButton类已经为我们处理了该操作.

I also faced the issue before. The GIDSignInButton object don't need addTarget in code or linking @IBAction. The GIDSignInButton class already handle that action for us.
