我正在使用Xcode 9，并将编译器设置为Swift 3.2
我安装了带有Cocoapods的Facebook Login，并且所有编译都没有任何错误，但是每当我在模拟器中运行它时，我都单击登录按钮，它崩溃了，仅在控制台中打印了此内容:
libc ++ abi.dylib:以NSException类型的未捕获异常终止
(lldb)
这是我的ViewController.swift:
import UIKit
import FBSDKLoginKit
import FacebookLogin
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let loginButton = LoginButton(readPermissions: [ .publicProfile ])
loginButton.center = view.center
view.addSubview(loginButton)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
这是我的AppDelegate.swift
import UIKit
import FBSDKCoreKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
return true
}
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
let handled = FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options [UIApplicationOpenURLOptionsKey.sourceApplication] as! String!, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
return handled
}
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:.
}

最佳答案
在AppDelegate，didFinishLaunchingWithOptions中，您必须返回从sharedIstance.application(....)返回的布尔值:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
let bool = FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
FBSDKAppEvents.activateApp()
return bool
}

Info.plist后，您应该会看到类似的内容。 FacebookAppID和FacebookDisplayName是必需的:关于ios - xcode 9中的Facebook登录按钮终止，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/46387724/
