Rg.plugins.popup: UI becomes not responsive after the dialog is closed ( iOS )
I am calling it with :
public static void simplePopup( string message )
{
onConfirmClicked = null;
messageText = message;
captionText = "test";
if( dialogInstance == null )
{
try
{
dialogInstance = new SimpleDialog();
}
catch( Exception ex )
{
}
}
try
{
( App.instance.MainPage as ExtendedNavigationPage ).Navigation.PushPopupAsync( dialogInstance );
}
catch( Exception ex )
{
}
}
and I am closing it from a "OK" button within the class with the follow code:
private void onButtonConfirmationClicked( object sender, EventArgs e )
{
try
{
if( onConfirmClicked != null )
onConfirmClicked();
}
catch( Exception ex )
{
}
try
{
//( App.instance.MainPage as ExtendedNavigationPage ).Navigation.PopAllPopupAsync();
( App.instance.MainPage as ExtendedNavigationPage ).Navigation.RemovePopupPageAsync( dialogInstance );
}
catch( Exception ex )
{
}
}
anyway - once the dialog is closed the page which is on top of the modal stack becomes with not responsive UI.

@YordanYanakiev Hi. RemovePopupPageAsync and PopAllPopupAsync are async methods. Your should invoke them in the main UI thread and should use an await operator like this:
private async void onButtonConfirmationClicked( object sender, EventArgs e )
{
try
{
if( onConfirmClicked != null )
onConfirmClicked();
}
catch( Exception ex )
{
}
try
{
//( App.instance.MainPage as ExtendedNavigationPage ).Navigation.PopAllPopupAsync();
await ( App.instance.MainPage as ExtendedNavigationPage ).Navigation.RemovePopupPageAsync( dialogInstance );
}
catch( Exception ex )
{
}
}

if add "await" and turn the click handler into async - the code above throws an Exception ( null ).

@YordanYanakiev Remove try/catch and give me a stack trace from output view after an application crashing.

Confirmed. It was a bug in Xamarin Forms 2.3.4.x as You suggested rotorgames !
Thank You VERY VERY much!

@YordanYanakiev It is not a Xamarin.Forms bug just I forgot to update a min Xamarin.Forms version in nuget. Fixed in v1.1.0-pre9.
