集成Facebook SDK

Question

我正在製作應用程序，我想整合Facebook，但是這個錯誤無法繼續，附加了我的問題。

import UIKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

    var window: UIWindow? 


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 

     FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) 
     // Override point for customization after application launch. 
     return true 

    } 
    func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool { 

     return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation:annotation) } THIS IS THE PROBLEM -- > ////Use of unresolved identifier "sourceApplication"/// 
    } 
}

您的委託方法與Facebook使用的方法不匹配。那樣的事情呢？

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool { 
    return FBSDKApplicationDelegate.sharedInstance().application(app, openURL: url, sourceApplication: options[UIApplicationOpenURLOptionsSourceApplicationKey] as? String, annotation: options[UIApplicationOpenURLOptionsAnnotationKey]) 
}
