# pressesChanged(_:with:)

Tells this object when a value associated with a press has changed.

## Declaration

```swift
func pressesChanged(_ presses: Set<UIPress>, with event: UIPressesEvent?)
```

## Parameters

- `presses`: A set of doc://com.apple.uikit/documentation/UIKit/UIPress instances containing changed values.
- `event`: The event to which the presses belong.

## Discussion

Discussion UIKit calls this method when an analog value associated with a button or thumbstick changes. For example, it calls this method when the analog force value of a push button changes. Use this method to take any needed actions in response to the change. The default implementation of this method forwards the message up the responder chain. When creating your own subclasses, call super to forward any events that you don’t handle yourself.
