@JonB , Thank you!! I'll try.

@Gerzer said:

Patience is a virtue! Does the button partially appear only in landscape? Or does the problem occur in portrait as well?

Start program at portrait. When rotate phone button was partially apearing.

Any comment?

I use this code.

import ui

def button_tapped(sender):
    v = ui.View()
    v.background_color = 'green'
    v.name = 'Pushed View'
    sender.navigation_view.push_view(v)

root_view = ui.View()
root_view.background_color = 'white'
root_view.name = 'Root View'

button = ui.Button(title='Tap me')
button.action = button_tapped
button.bring_to_front()
button.background_color = 'gray'
root_view.add_subview(button)
nav_view = ui.NavigationView(root_view)
nav_view.present()

When I rotate my Iphone the button is cutting.

How to fix it? Thanks..

And I have another questions. Can I run some script when user pressed the button 'back' at the navigation view? Thanks.

Thank you).

Thank you a lot! Problem was in that - button was created but in left upper conner - very high. I move scroll view down and now all works right!!
Now I have new questions) - can i add 2 ui.label in each raw in table view?

I start new script and do this. I have the same

No Name - it is not control. It is standart title... Scroll view I move to back. There obly 2 objects - scroll view and buuuton. All in the center with standart sizes.
Action from button have executed and I can change with this action for example content_size, but I can not add button!
I can change in scrollView anything, but can`t add new ui element

@Phuket2, Yes I have correct names.

    myScrollView=v['scrollview1']
    butt = ui.Button(title='test')
