What is a module ?

you have to understand two things to understand the module ,

Moduls View Controller

Moduls = > just think it's a place to save any information you will need it in your app , example

if i have array of country names , i will create new class i will called => AppInfo.h / AppInfo.m

now whenever i need this information i will call this class and i will call the array , that mean the class is response to store the informations only , not doing any calculation just storing , so that was only an example storing country on class , but on the real instate of storying country in array , we can store them in database , core data , iCloud and we can call them our modules ,

now that was about modules

about view

whenever your information is displaying , the place for displaying this information is called view

finally is controller ,

As i said view is displaying the information from module but the question is who will call this information from modules to view ?

this we called controller because he is controlling the things between modules and view .

i hope that make help.

As I understand it, a module is a complete piece of code that allows you to do something ideally in one class.. say for example a User class.. that allows you to add/edit/delete/ users.. you would pull that into your project as module so that you don't have to reinvent the wheel (re-write what is available already)

Mr shez , as your example, the clas whose doing Add Edit Delete

This we called controller, but , the place where the data is stored we called model , example of models Core Data, SQlite ..
