iOS Question Change App.KeyController

mkh_fx · Apr 26, 2017

hi everyone
in my first Layout i have used TabBarController
i change the KeyController by this code

B4X:

Sub pnl_category_Click
    Main.App.KeyController = Main.NavControl
    frm_showcategory.Show
End Sub

But when I do change the black screen to be displayed
this my code in frm_showcategory.show

B4X:

Public Sub Show
        page_showCategory.Initialize("frm_showcategory")      
        page_showCategory.RootPanel.LoadLayout("frm_showcategory_sv")
        main_sv.Panel.LoadLayout("frm_showcategory")
        Main.NavControl.NavigationBarVisible  =True
        Main.NavControl.ShowPage(page_showCategory)

End Sub

Make sure not to create a new page each time. See this example: Multiple Pages Example

Is the problem the black bar at the top?

Have you tried to show the page and then call NavigationBarVisible = True ?

    If (page_showCategory.IsInitialized = False) Then

You should upload it to the forum. If it is not possible then try to reproduce it in a small project and upload it.
