我遇到了一个错误,建立在一个sigabrt错误的AppDelegate文件。我已经阅读过很多关于sigabrt的其他主题,但是我正在问如何解决这个sigabrt错误,因为它与Google Sign In有关。错误Sigabrt与谷歌登录Xcode
ViewController.swift代码:
import UIKit
import GoogleSignIn
import Firebase
class ViewController: UIViewController, GIDSignInUIDelegate {
override func viewDidLoad() {
super.viewDidLoad()
setupGoogleButtons()
}
fileprivate func setupGoogleButtons(){
//default google sign in button
let googleButton = GIDSignInButton()
googleButton.frame = CGRect(x: 16, y: 116 + 80, width: view.frame.width - 32, height: 50)
view.addSubview(googleButton)
//custom google sign in button
let customButton = UIButton(type: .system)
customButton.frame = CGRect(x: 16, y: 116 + 80 + 66, width: view.frame.width - 32, height: 50)
customButton.backgroundColor = .blue
customButton.setTitleColor(.white, for: .normal)
customButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 14)
customButton.setTitle("Google Sign In #2", for: .normal)
customButton.addTarget(self, action: #selector(handleCustomGoogleSignIn), for: .touchUpInside)
view.addSubview(customButton)
}
func handleCustomGoogleSignIn() {
GIDSignIn.sharedInstance().signIn()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
的AppDelegate文件代码:
import UIKit
import Firebase
import GoogleSignIn
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FIRApp.configure()
GIDSignIn.sharedInstance().clientID = FIRApp.defaultApp()?.options.clientID
GIDSignIn.sharedInstance().delegate = self
return true
}
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
if let err = error {
print("Failed to log into Google: ", err)
return
}
print("Successfully logged into Google", user)
guard let idToken = user.authentication.idToken else { return }
guard let accessToken = user.authentication.accessToken else { return }
let credentials = FIRGoogleAuthProvider.credential(withIDToken: idToken, accessToken: accessToken)
FIRAuth.auth()?.signIn(with: credentials, completion: { (user, error) in
if let err = error {
print("Failed to create a Firebase User with Google account: ", err)
return
}
guard let uid = user?.uid else { return }
print("Successfully logged into Firebase with Google", uid)
})
}
func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey: Any] = [:]) -> Bool {
GIDSignIn.sharedInstance().handle(url,
sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String,
annotation: options[UIApplicationOpenURLOptionsKey.annotation])
return true
}
}

让我知道是否有其他任何需要被包括在内。
请仔细阅读错误消息。关键信息是''uiDelegate必须是| UIViewController |或实现| signIn:presentViewController:|和| signIn:dismissViewController:|方法来自| GIDSignInUIDelegate | .'' – vadian
@vadian所以你知道如何解决这个错误,因为我没有完全理解它那么好 –
因为'AppDelegate'不是视图控制器,所以你需要实现建议的方法。 – vadian
