Answer from AI
UIControl is a base class in iOS that represents interactive elements of the user interface, such as buttons, switches, sliders, etc.
The role of UIControl includes:
- Handling user events (taps, touches, value changes).
- Managing control states (e.g., highlighted, disabled).
- Allowing the addition of target-action pairs, which are called upon specific events.
Thus, UIControl serves as the foundation for creating interactive elements, providing a mechanism for user interaction.
Example of usage:
let button = UIButton(type: .system)
button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
@objc func buttonTapped() {
print("Button tapped")
}
