Xamarin Forms iOS showed two pages?

[SuhanKoh]

Xamarin.Auth Issue

When I use Xamarin.Auth with Xamarin.Auth.XamarinForms package, And after I logged in with OAuth2, it does not dismiss the 'root'. The 'root' is a page with back button that is called by Xamarin.Auth.

Version

• [x] nuget version = 1.50.

Steps to reproduce

1. On ShowLogin, call new Xamarin.Auth.XamarinForms.AuthenticatorPage() and pass in the authenticator.

Expected behaviour

After logged in, the webview should dismissed. Which was the behavior if I do not use Xamarin.Forms and implement it into Xamarin.iOS.

I also have the same issue. Hitting cancel in iOS leaves me at a blank white page (the first of the two pages you mentioned). Hitting back in Android leaves me at a blank white page also, then I can press back again to dismiss this and go back to my original page.

Hey @ytn3rd , I solved this issue by digging it into the source code.

For Xamarin.Forms.Android, you got to add a similar line like FormsMap, add to MainActivity.cs global::Xamarin.Auth.Presenters.XamarinAndroid.AuthenticationConfiguration.Init(this, bundle);

For Xamarin.Forms.iOS, you got to add [below] in AppDelegate.cs global::Xamarin.Auth.Presenters.XamarinIOS.AuthenticationConfiguration.Init();

Also last but not least, make sure you have Xamarin.Auth.XamarinForms NuGet installed.

Those should be the other way around :P but yeah I see what you mean.

I was also trying to present an AuthenticatorPage but instead I used what the evolve sample did.

 // Presenters Implementation
Xamarin.Auth.Presenters.OAuthLoginPresenter presenter = null;
presenter = new Xamarin.Auth.Presenters.OAuthLoginPresenter();
presenter.Login(authenticator);

Everything seems to work fine. Can you close this issue now @SuhanKoh ?

[SuhanKoh]

@ytn3rd Thanks :P should I close it? I think Xamarin should update their document about this..

[beeradmoore]

Open source project, we should add the new stuff to the README.wd and do a pull request.

Unsure if it belongs in a 1.0 topic on there, or 2.2. The readme.detailed in the wiki has it in under 2.2.

@ytn3rd You are right - it is open source and PRs are welcome.

Xamarin.Forms support contains Presenter[s] and CustomRenderer[s]. Presenters are more tested than CustomRenderers. I have added some fixes to the CustomRenderers, but we moved build system to public jenkins and not everything was setup, so I had to wait.

Fixes are in 1.5.0.1 nuget

https://www.nuget.org/packages/Xamarin.Auth/

Please report if this fixes the CustomRenderers issues.

NOTE: redame.detailed is still under heavy construction (read: mess).

@SuhanKoh

I think Xamarin should update their document about this

On this library Xamarin == {me, myself, I}, so 24:00 hrs day is quite short to fulfil wishes of every user.

Closing is welcome if the problem is fixed. Thanks

@moljac Understood, I will change readme if it still needed when the customrenderer gets updated.
