Buttons are made for clicking, or in iOS, tapping. This movie demonstrates the basics of responding to button presses in iOS. Using this basic interaction effectively helps build a foundation for developing apps. The process involves connecting a button to code and handling the touch event inside your code.
Learn how to create native apps for iOS 9, the latest operating system for the iPhone and iPad. It all starts with the installation of Xcode, the free all-in-one development environment built by Apple. Author Todd Perkins then shows how to select an app template and start working on the core iOS programming skills: creating interactions; responding to touch events, button clicks, and text input; and using delegation. He also spends a few chapters on iOS interface design. In these sections, you’ll learn how to use Interface Builder to visually design your app’s UI and use size classes to responsively adjust to different screen sizes. Plus, find out how to use views to display images, web content, and table data, and transition seamlessly between views in multiview apps.

In addition to dividing the application into three kinds of components, the model–view–controller design defines the interactions between them.
- A model stores data that is retrieved according to commands from the controller and displayed in the view.
- A view generates an output presentation to the user based on changes in the model.
- A controller can send commands to the model to update the model’s state (e.g. editing a document). It can also send commands to its associated view to change the view’s presentation of the model (e.g. by scrolling through a document).
MVC is useful because it separates the functionality of data storage, data representation, and user interaction. Under this framework, it is possible to manipulate how a end user will see data without affecting the data itself. It is popular in the world wide web because it provides an clean organization and structure to applications that require user interaction.
