@JonB Wonderful, it works! I used the code:
tb.superview().superview().addSubview_(btn_obj)
(Thanks @cvp)
Really, @JonB how can you know these things? However, now I have a code that creates, every time I launch Pythonista, two buttons, at left and at right of upper bar. The left one, if touched, shows six little squares buttons (one button for one action). The right one, if touched, hides the six buttons.
Maybe you will find this a little easy, but for me it is a great thing ;-)
Two questions:
1. How can I program the left button in order to use it both for showing and hiding of the six user buttons? I mean, when the six buttons are showed, touching the left button should hide them; when the six buttons are hidden, touching the left button should show them.
2. Can Pythonista execute automatically a script every time user changes iphone screen from portrait to landscape and viceversa? Inside 'pythonista_startup.py'?
@cvp thank you for info about buttons size. But the last two values in:
btn=ui.Button( frame=((index)*40,22,40,40))
are a bit strange for me: what do they mean (40 and 40)?
And I can't show any text inside my buttons. Can you kindly show me what and where I must add some code for button text? Let's imagine the user button must show the text "Copy": what should I do in the following code (JonB's apphack.py) to add text inside the button?

Thank you so much!

the extra bar under the main one will hide the filename , the run button |≥ and some other built-in keys. But this is not a problem because user can hide the two bars with one touch on the half button in high corner in order to use run key or others.
