# UIControl.Event

Constants describing the types of events possible for controls.

## Declaration

```swift
struct Event
```

## Mentioned in

Responding to control-based events using target-action

## Overview

Overview You set up a control so that it sends an action message to a target object by associating both target and action with one or more control events. To do this, send addTarget(_:action:for:) to the control for each target-action pair you want to specify.
