最近每次我尝试使用 Facebook 登录时,它都不起作用,并且显示以下错误。这发生在 iOS 模拟器和实际设备上。

它显示 ViewController 允许用户登录,但是当我单击继续时,它会抛出以下错误,然后 View 变为空白。如果我然后按“完成”关闭 FB View Controller ,它会使应用程序完全崩溃。
Facebook login was cancelled by user.

直到几天前它都工作正常,我只是不知道为什么它突然停止工作,因为我没有改变任何东西。
let facebookLogin = FBSDKLoginManager()
facebookLogin.logIn(withReadPermissions: ["email", "user_friends", "public_profile"], from: self.view?.window?.rootViewController) { (result, error) in
if result?.isCancelled == true {
self.fbLoginError()
} else if error == nil {
let credential = FIRFacebookAuthProvider.credential(withAccessToken: (result?.token.tokenString)!)
FIRAuth.auth()?.signIn(with: credential, completion: { (user: FIRUser?, error:Error?) in
if error == nil {
print("FB and Firebase Login Successful")
})
} else {
print(error)
self.fbLoginError()
}
})
} else {
print(error)
self.fbLoginError()
}
}
应用程序委托(delegate)
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FBSDKProfile.enableUpdates(onAccessTokenChange: true)
FIRApp.configure()
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
return true
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}
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.
FBSDKAppEvents.activateApp()
}
它永远不会命中任何 if 语句,只是忽略完成闭包中的所有内容。
我还启用了钥匙串(keychain)共享

最佳答案
尝试这样!
Appdelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FIRApp.configure()
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
let handled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
return handled
}
func applicationDidBecomeActive(_ application: UIApplication) {
FBSDKAppEvents.activateApp()
}
ViewController.swift
@IBAction func facebookLogin(sender: UIButton) {
let fbLoginManager = FBSDKLoginManager()
fbLoginManager.logIn(withReadPermissions: ["public_profile", "email"], from: self) { (result, error) in
if let error = error {
print("Failed to login: \(error.localizedDescription)")
return
}
guard let accessToken = FBSDKAccessToken.current() else {
print("Failed to get access token")
return
}
let credential = FIRFacebookAuthProvider.credential(withAccessToken: accessToken.tokenString)
// Perform login by calling Firebase APIs
FIRAuth.auth()?.signIn(with: credential, completion: { (user, error) in
if let error = error {
print("Login error: \(error.localizedDescription)")
let alertController = UIAlertController(title: "Login Error", message: error.localizedDescription, preferredStyle: .alert)
let okayAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(okayAction)
self.present(alertController, animated: true, completion: nil)
return
}
// Present the main view
if let viewController = self.storyboard?.instantiateViewController(withIdentifier: "MainView") {
UIApplication.shared.keyWindow?.rootViewController = viewController
self.dismiss(animated: true, completion: nil)
}
})
}
}
