Call back when user presses GIDSignInButton

问题

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?

回答1:

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()
}
