# addTarget(_:action:)

Adds a target and an action to a gesture-recognizer object.

```
func addTarget(_ target: Any, action: Selector)
```

## Parameters

`target`

An object that is a recipient of action messages sent by the receiver when the represented gesture occurs. `nil` is not a valid value.

`action`

A selector identifying a method of a target to be invoked by the action message. `NULL` is not a valid value.

## Discussion

You may call this method multiple times to specify multiple target-action pairs. However, if you request to add a target-action pair that has already been added, then the request is ignored.

## See Also

[`init(target:action:)`](/documentation/UIKit/UIGestureRecognizer/init(target:action:))
