How does an app works?

In this course, we will learn the precise operations of an iOS application. Many of us use our mobile devices every day, yet most people are unaware of how applications function on these devices.

As an illustration, one of our applications contains a login screen. The Login button, Email ID, Password, and other items can all be found on the login screen.

After entering his email address and password, the user clicked the log-in button. Therefore, the application verifies the email address and password upon clicking the login button. We can log into the application if all the requirements are satisfied.

Therefore, the focus of this session will be on what is precisely happening in the background.

How does an application work?

Consider the case when we have a single button on an application. And if the user tapped on that one button, the phone’s sensors recorded the tap and sent an event to the operating system.

Please see the picture below.

iOS application workflow

What is Application?
A set of codes make up an application or an app. The app functions in accordance with the code or program that we write.

What is OS?
OS is a shorthand for the operating system. OS delivers services to the computer program and controls hardware and software resources.

What is iOS?
The iPhone operating system is known as iOS. Apple is the company that designed and developed this mobile operating system.

OS examines and reads the message it receives from the sensors such as how much pressure is put on the phone and where on the phone.

The OS uses that data to carry out some background actions; once those operations are complete, the OS recognizes that this button is for the specified application.

The OS then notifies the application that its button has been tapped and requests that it respond.

The application then examines the code and executes the button action we defined. the application then operates in accordance with button clicks

That’s it.😎
