我正在将Google登录信息添加到我的应用程序中.我已在情节提要中添加了GIDSignInButton.当用户单击该按钮时，用户将被发送到可以登录的网页. 我想做一些检查，然后再做.在将用户定向到网页之前，有什么方法可以获取回叫方法?

I am adding Google sign-in to my app. I have added GIDSignInButton in storyboard. When user clicks on that button user is sent to webpage where he can login. I wanted to do some checks before it happens. Is there any way that I can get a call back method before user is directed to webpage?

推荐答案

您可以创建具有相同外观的任何按钮并将其挂钩到该动作

You can create any button with same look and hook it to this action

@IBOutlet func btnClicked(_ sender:UIbutton) {
    // do what you want use return if checks are failed 
    GIDSignIn.sharedInstance().signIn()
}
