FBSDKAppEvents.activateApp（）发送到实例的无法识别的选择器

Question

我正在尝试在我的应用中整合facebook sdk，我已经完成了所有info.plist并导入了sdk步骤。当过我跑我的应用程序，首先当viewloads我得到这个错误

这是我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（）它工作正常。

这发生在我身上一次，确保FacebookAppId设置为字符串不在info.pList中的数字
