ios - application:openURL:sourceApplication:annotation的实现

我在Xcode8发行之前开始使用该应用程序，然后进行切换，当我尝试使用Facebook登录名登录该应用程序时，出现以下错误

找不到application:openURL:sourceApplication:annotation:的实现。请将处理程序添加到您的应用程序委托中。类:GhostGab.AppDelegate

我检查了所有设置，它们看起来还不错。任何帮助将不胜感激

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    FIRApp.configure()
    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    return true
}

  func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {

    let facebookDidHandle = FBSDKApplicationDelegate.sharedInstance().application(
        application,
        open: url,
        sourceApplication: sourceApplication,
        annotation: annotation)
    // Add any custom logic here.
    return facebookDidHandle
}

最佳答案

您的函数定义:

func application(application: UIApplication, openURL url: URL, sourceApplication: String?, annotation: AnyObject) -> Bool {
}

应替换为:

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
}

第一个参数带有下划线，而最后一个参数类型则带有Any而不是AnyObject。

这就是为什么出现错误的原因:
