ios - 在 Swift 中使用 facebook 登录 api 时出现 "Open this page in APP_NAME"

Question

我在我的 ios 应用程序的 Swift 中使用 facebook 登录 api(SDK 版本可选("4.1.0"))。我将 Facebook 登录按钮放在我的 View Controller 上，当用户单击它时 - 它会在 Safari 中打开 Facebook 登录面板。当用户输入凭据并单击登录时，他会看到带有问题的弹出消息:

Open this page in APP_NAME?

Cancel                OPEN

我想摆脱它并直接打开应用程序。我处理按钮行为的代码如下:

class ViewController: UIViewController, FBSDKLoginButtonDelegate {
    @IBOutlet weak var fbLoginButton: FBSDKLoginButton!

override func viewDidLoad() {
    super.viewDidLoad()
    fbLoginButton.readPermissions = ["public_profile", "email"]
    fbLoginButton.layer.cornerRadius = 5
    fbLoginButton.delegate = self
    self.fbLoginButton.delegate = self
    FBSDKProfile.enableUpdates(onAccessTokenChange: true)
}

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    if (FBSDKAccessToken.current() != nil){

        let tokenAsAParam = [
            "access_token":FBSDKAccessToken.current().tokenString!
        ]

        let loginManager = FBSDKLoginManager()

        FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email"]).start(completionHandler: { (connection, result, error) -> Void in
            if (error == nil){
                let data:[String:AnyObject] = result as! [String : AnyObject]
                let defaults =  UserDefaults.standard
                let firstName:String = data["first_name"] as! String!

                defaults.set(firstName, forKey: "facebook_display_name")
                defaults.synchronize()
            }else {
                print("fb error")
            }
        })

        Alamofire.request("\(serverURL)/auth/facebook", method: .post, parameters: tokenAsAParam)
            .validate()
            .responseJSON { response in

                switch(response.result) {

                case .success:
                     self.performSegue(withIdentifier: "openMainApp", sender: self)
                    break
                case .failure:
                    print(response.result.error)
                    loginManager.logOut()
                break
              }
      }
     }

在上面的代码中，我从 Facebook 获取用户的数据，并将 token 发送到我的网络服务，以验证用户是否真实，并执行一些后端操作。

我的 info.plist 文件是:

<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fbXXXXXXXXXX</string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>2XXXXXXXXXXX</string>
<key>FacebookDisplayName</key>
<string>xxxxxxxx</string>
<key>LSApplicationCategoryType</key>
<string></string>
<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

此外，在我的 appDelegate 中，我有以下方法:

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

    FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
    print("SDK version \(FBSDKSettings .sdkVersion())")

 ...
    return true
}



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

    return FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: sourceApplication, annotation: annotation)
}
// [END openurl]

@available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {

    return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String?, annotation: options[UIApplicationOpenURLOptionsKey.annotation])
}

但它仍然显示这个奇怪的弹出窗口，而不是正常打开应用程序。

有谁知道我可以做些什么来解决这个问题？
