Troubles with native login

[leshik]

Hi,

I'm unable to login through native FB app on iOS, but the login works just fine with web popup. I tried to enable keychain sharing capability as cordova-plugin-facebook4 FAQ suggests, but it didn't help. Their plugin doesn't work either.

What might be the reason?

Hello,

Did you configure AppDelegate.swift as explained?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
}

Sure I did. Should I use other callback(s) maybe?

@sebdej I was able to make it work by adding the following code:

  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {

    // The code that I added:
    if let scheme = url.scheme, let host = url.host {
      if scheme == "fb\(SDKSettings.appId)" && host == "authorize" {
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
      }
    }
    // end of the code snippet

    return CAPBridge.handleOpenUrl(url, options)
  }

@sebdej now I have similar problem on Android – web popup works just fine, but nothing happens when native FB app is installed, it doesn't even try to open it. What might be the reason?

@sebdej I was able to make it work by adding the following code:

  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {

    // The code that I added:
    if let scheme = url.scheme, let host = url.host {
      if scheme == "fb\(SDKSettings.appId)" && host == "authorize" {

      }
    }
    // end of the code snippet

    return CAPBridge.handleOpenUrl(url, options)
  }

Yes, you're right, I have a similar handler, in my AppDelegate class, I will update the documentation.

Oh I'm sorry – it actually works! That was my mistake on Android.
