# WebPolicyDecisionListener

This protocol enables [`WebView`](/documentation/WebKit/WebView-swift.class) policy delegates to communicate with listener objects. A listener object conforming to this protocol is passed as one of the arguments to web view policy delegate methods.

```
protocol WebPolicyDecisionListener : NSObjectProtocol
```

## Overview

This protocol allows delegates to handle download decisions asynchronously. For example, the policy delegate may display a sheet, and the listener object gets notified only after the user clicks an OK or Cancel button. You do not directly create objects that conform to this protocol.

### Making Resource-Usage Decisions

[`download()`](/documentation/WebKit/WebPolicyDecisionListener/download())

[`ignore()`](/documentation/WebKit/WebPolicyDecisionListener/ignore())

Tells the listener to ignore the resource.

[`use()`](/documentation/WebKit/WebPolicyDecisionListener/use())

Tells the listener to use the resource.
