Common UI Controls and Events

User Interface (UI) controls are the interactive elements users see and touch in an app. They are the building blocks of any iOS application's visual experience.

• Buttons: Tap to perform actions.
• Labels: Display static text.
• Text Fields: Input text from the user.

Mastering these controls is crucial for creating intuitive and functional apps, especially when maintaining legacy Objective-C codebases.

A UILabel is used to display static, read-only text in your app. Think of it as a sign or a description.

• Set its text property to display content.
• Customize its appearance with properties like textColor, font, and textAlignment.
• Labels can be single or multi-line.

It's one of the most fundamental UI elements you'll encounter.
