# removeTarget(_:action:for:)

Stops the delivery of events to the specified target object.

```
func removeTarget(_ target: Any?, action: Selector?, for controlEvents: NSControl.Events)
```

## Parameters

`target`

A target object registered with the control. Specify `nil` to remove the specified control events for all target objects.

`action`

A selector identifying a registered action method. You may specify `nil` for this parameter.

`controlEvents`

A bit mask specifying the control events to remove for the specified `target` object. For a list of possible constants, see [`NSControl.Events`](/documentation/AppKit/NSControl/Events).

## Discussion

Use this method to prevent the delivery of control events to a target object. If you specify a valid object in the `target` parameter, this method stops the delivery of the specified events to all action methods associated with that object. If you specify `nil` for the `target` parameter, this method prevents the delivery of those events to all action methods of all target objects.
