Question

我已经通过我的应用程序成功登录Facebook大概50到100次，但现在它无法正常工作。我得到了登录屏幕并且可以输入我的FB登录信息或者由于已经登录而点击继续。当登录屏幕被解除时，回调被调用但是result.isCancelled总是为真。这是我正在使用的委托函数：

func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result:
    FBSDKLoginManagerLoginResult!, error: Error!) {

    print(result.isCancelled)       //always returning true
}

以下是appDelegate中的内容：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

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

    return true
}

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

    let handled = FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)

    return handled
}

func applicationDidBecomeActive(_ application: UIApplication) {

    FBSDKAppEvents.activateApp()
}

有没有办法检查应用的激活状态？我想知道问题是否在一般设置中（例如，p-list，Facebook开发者网站等）。

更新：我现在也在FB股上崩溃，我之前也检查过。这是错误消息。似乎这些必须是相关的。

Swift FB登录总是返回“isCancelled”
