• My approach would follow @dgelessus advise...

    import time, ui @ui.in_background def myaction(sender): sender.superview["Record_label"].text = "START" # write to the label time.sleep(2) # delay for a bit sender.superview["Record_label"].text = "END" # write to the label def make_button(title='Click me'): button = ui.Button(name=title, title=title) button.action = myaction return button def make_label(text='Who cuts your hair?'): label = ui.Label(name='Record_label', frame=(50, 50, 200, 32)) label.text = text label.text_color = 'blue' return label if __name__ == '__main__': view = ui.View() view.add_subview(makes_button()) view.add_subview(make_label()) view.present() view['Click me'].center = view.center

    Although it does not solve the two button problem that @JonB raises, ui.in_background does run myaction in a way that does not degrade the responsiveness of your UI. See: http://omz-software.com/pythonista/docs/ios/ui.html#ui.in_background

  • Lukas,

    I got it. That works! Thanks.

    May you live to be one-thousand years old, sir.
