Question

我想要做的是在使用Firebase成功验证后转到相应的视图控制器。因此，当用户单击“登录”时，它会检查凭据是否正确，然后如果它们是，它将转到我的下一个视图控制器。这就是我所拥有的，我不断收到错误“线程1：信号SIGABRT”

这是我的viewController.swift

import UIKit
import Firebase
import GoogleSignIn

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FirebaseApp.configure()
    return true
}
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any])
    -> Bool {
        return GIDSignIn.sharedInstance().handle(url,
                                                 sourceApplication:options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
                                                 annotation: [:])
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
    return GIDSignIn.sharedInstance().handle(url,
                                             sourceApplication: sourceApplication,
                                             annotation: annotation)
}

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:.
}

这是我的AppDelegate.swift

{{''}}

}

我想在视图控制器之间移动一个segue，它的标识符是“signin”

Answer 1

我的问题在于，当我推送到下一个视图控制器时，它不再具有电子邮件和密码的文本字段。通过将登录功能切换到另一个.swift文件，并将其视图控制器切换到另一个类，它不再在加载时查找它们，现在它可以完美地工作！

performSegue成功登录 - Firebase / Swift
