>我通过cocoapods安装了GoogleSignIn. pod’GoogleSignIn’,’〜> 2.4.0′

func signIn(signIn: GIDSignIn!, didDisconnectWithUser user: GIDGoogleUser!, withError error: NSError!) {

它将我重定向到google.com,而不是应用程序.

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool
{
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

Google通过URL发回信息,上述方法会捕获此信息并发送回应用程序.
