How to implement communication with UI in Pythonista?

Question

Python

Working with Pythonista , I can't figure out GUI implementations with UI Designer . It is necessary to implement the launch of two functions by clicking on two different buttons and displaying an image.

Answer 1

Here it is without ui designer:
# coding: utf-8
import ui
def button_tapped(sender):
sender.title = 'Hello'
view = ui.View()
view.name = 'Demo'
view.background_color = 'white'
button = ui .Button(title='Tap me!')
button.center = (50, 25)
button.flex = 'LRTB'
button.action = button_tapped
button.background_color = 'green'
view.add_subview(button)
view.present(' sheet')
There is good documentation for ui designer
