Packaging Python script for iOS


In this recipe, we will be learning to package a Python script for iOS. iOS is a mobile operating system developed by Apple Inc for its devices, including the iPhone, iPad, and iPod Touch. To write, test and run this application, we will be requiring a Macintosh computer.

First of all, we will be creating a Kivy Python script that comprises a button and a label. When a button is clicked, the application simply displays the message Welcome to Python on Smartphones. This Kivy Python script is made in a folder. So, create a folder named helloworld and write the following code in a file named main.py:

from kivy.app import Appfrom kivy.uix.button import Button
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
class WelcomeApp(App):
   def build(self):
        layout = BoxLayout(orientation='horizontal')
        pushButton =  Button(text='Click Me')       
        pushButton.bind(on_press=self.showMessage)
        self.labelMessage = Label...
