ios - FBSDKAppEvents.activateApp() 无法识别的选择器发送到实例

Question

我正在尝试将 facebook sdk 集成到我的应用程序中，我已经完成了所有 info.plist 和导入 sdk 的步骤。每当我运行我的应用程序时，第一次查看加载时我都会收到此错误

libc++abi.dylib: terminating with uncaught exception of type NSException

这是我的 appdelegate.swift

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.                

        return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    func application(application: UIApplication, openURL url: NSURL, sourceApplication: NSString?, annotation: AnyObject) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
    }



    func applicationWillResignActive(application: UIApplication) {

    }

    func applicationDidEnterBackground(application: UIApplication) {

    }

    func applicationWillEnterForeground(application: UIApplication) {
        // Called as part of the transition from the background to the inactive 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.

        FBSDKAppEvents.activateApp()
    }

    func applicationWillTerminate(application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }


}

当我删除 FBSDKAppEvents.activateApp() 时它工作正常。

这发生在我身上一次，确保 FacebookAppId 在 info.pList 中设置为字符串而不是数字
