FBLogin libc++abi.dylib:以NSException类型的未捕获异常终止

Question

我已经基于FB文档配置了所有内容https://developers.facebook.com/docs/ios/getting-started/但我的应用程序在点击FBLoginButton后崩溃，你能告诉我代码中缺少什么吗？这是我的吊舱

pod 'FBSDKCoreKit'
pod 'FBSDKLoginKit'

我正在基于swift 4.2、xcode 10和ios 12进行开发这是我为AppDelegate和ViewController编写的代码：

AppDelegate

import UIKit
import FBSDKCoreKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(application,
didFinishLaunchingWithOptions: launchOptions)
window = UIWindow(frame: UIScreen.main.bounds)
window?.makeKeyAndVisible()
window?.rootViewController = UINavigationController(rootViewController: ViewController())
return true
}
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
let handled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as! String?, annotation: options[UIApplication.OpenURLOptionsKey.annotation])
return handled
}
//...
}

和ViewController

import UIKit
import FBSDKLoginKit
class ViewController: UIViewController, FBSDKLoginButtonDelegate{
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = FBSDKLoginButton()
view.addSubview(loginButton)
loginButton.frame = CGRect(x: 16, y: 50, width: view.frame.width - 32, height: 50)
loginButton.delegate = self
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
if error != nil {
print(error)
return
}
print("Successfully logged in with facebook...")
}
func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
print("Did log out of facebook")
}
}

我错过了在info.plist中的以下配置中添加APP_ID添加APP_ID后，应用程序连接到FB。

<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>fb{APP_ID}</string>
</array>
</dict>
</array>
