ios - 使用未解析的标识符 sourceApplication Facebook SDK

Question

以下代码实现FB登录我的应用

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

但是我不断收到两条相似的错误消息，

“使用未解析的标识符‘注释’“使用未解析的标识符‘sourceApplication’

我不确定是什么导致了这个错误，但我感觉它的一些代码已被弃用。有谁知道当前的替代方案是什么？

appdelegate.swift

Answer 1

我在我的应用程序委托(delegate)中使用此代码并且工作完美

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

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