ios - Firebase GIDSignInButton "firing"/无需用户触摸或交互即可登录

Question

我使用 XCode 创建了一个新的 iOS 应用程序，并遵循了 adding Google SignIn 的 Firebase 指南.

当 viewDidLoad 完成时，我正在体验 Google 登录的开始，而不是当 GIDSignInButton 被用户交互触摸时。

我没有接触过 GIDSignInButton。

这是我的 Storyboard UIViewController:

这是我的 SignUpViewController:

import UIKit
import Firebase
import GoogleSignIn

class SignUpViewController: UIViewController, GIDSignInUIDelegate {

    @IBOutlet weak var btnSignInGoogle: GIDSignInButton!

    override func viewDidLoad() {
        super.viewDidLoad()

        GIDSignIn.sharedInstance().uiDelegate = self
        GIDSignIn.sharedInstance().signIn()


    }

}

还有我的 AppDelegate:

import UIKit
import Firebase
import GoogleSignIn

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {

    var window: UIWindow?


    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        // Use Firebase library to configure APIs
        FirebaseApp.configure()

        GIDSignIn.sharedInstance().clientID = FirebaseApp.app()?.options.clientID
        GIDSignIn.sharedInstance().delegate = self

        return true
    }

    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

    @available(iOS 9.0, *)
    func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any])
        -> Bool {
            return GIDSignIn.sharedInstance().handle(url,
                                                     sourceApplication:options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
                                                     annotation: [:])
    }

    //deprecated method iOS 8 and older
    func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
        return GIDSignIn.sharedInstance().handle(url,
                                                 sourceApplication: sourceApplication,
                                                 annotation: annotation)
    }

    // Mark: - GIDSignInDeletgate
    func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error?) {
        // ...
        if let error = error {
            // ...
            return
        }

        guard let authentication = user.authentication else { return }
        let credential = GoogleAuthProvider.credential(withIDToken: authentication.idToken,
                                                       accessToken: authentication.accessToken)
        // ...
    }

    func sign(_ signIn: GIDSignIn!, didDisconnectWith user: GIDGoogleUser!, withError error: Error!) {
        // Perform any operations when the user disconnects from app here.
        // ...
    }
}

发生这种情况是因为您在 viewDidLoad 中发出登录请求。您可以将其从 viewDidLoad 中移除。

override func viewDidLoad() {
    super.viewDidLoad()

    GIDSignIn.sharedInstance().uiDelegate = self

}
