User input doesn't disappear when I going to another scene

kevinjteran · July 13, 2016, 6:57am

Hello,

I have a problem, in my code creates a menu that is collected on the screen, when selected, the menu appears, and if I click on the button “publicar” moves to the scene, everything disappears under the user input box.

In general the input box doesn’t disappears when I tap a button and traslate to another scene.

I’d appreciate your help

The code is this.

Thanks.

native.* objects are not managed by Composer. Even though you can add them to a group for movement purposes (i.e. they move with the group), they are otherwise un-managed. native.* objects are best created in scene:show()'s “did” phase and removed in scene:hide()'s “will” phase.

Hi Rob, I don’t understand.

Can you show me a example please.

Thanks

Pd: I have this code at the end of my scene

Look at the edituser.lua scene here:
