虽然我认为我已经正确添加并设置了 FacebookMes​​sengerSDK，但当我单击共享按钮时，我一直收到此错误，目前该按钮只会显示信使，但它实际上并没有做任何事情。

LaunchServices：错误：没有为 URL 方案 fb-messenger- 注册的处理程序

这是我的 Plist 源代码的一部分，Facebook 开发者网站告诉我包括在内。

这是我的应用程序委托

导入 UIKit 导入 FBSDKCoreKit 导入 FBSDKMessengerShareKit

@UIApplicationMain 类 AppDelegate: UIResponder, UIApplicationDelegate, FBSDKMessengerURLHandlerDelegate {

var window: UIWindow?
var composerContext = FBSDKMessengerURLHandlerOpenFromComposerContext()
var replyContext = FBSDKMessengerURLHandlerReplyContext()


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

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

    let messengerURLHandler = FBSDKMessengerURLHandler()
    messengerURLHandler.delegate = self

    return true
}

//Other stuff was here but I removed it

func applicationDidBecomeActive(application: UIApplication) {

    FBSDKAppEvents.activateApp()
}

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

    let urlHandler = FBSDKMessengerURLHandler()

    if urlHandler.canOpenURL(url, sourceApplication: sourceApplication) {

        urlHandler.openURL(url, sourceApplication: sourceApplication)
    }

    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

//Messenger

func messengerURLHandler(messengerURLHandler: FBSDKMessengerURLHandler!, didHandleOpenFromComposerWithContext context: FBSDKMessengerURLHandlerOpenFromComposerContext!) {

    composerContext = context

}

func messengerURLHandler(messengerURLHandler: FBSDKMessengerURLHandler!, didHandleReplyWithContext context: FBSDKMessengerURLHandlerReplyContext!) {

    replyContext = context

}


}

有什么帮助吗？谢谢！
