# stopLoading()

Stops protocol-specific loading of the request.

## Declaration

```swift
func stopLoading()
```

## Discussion

Discussion When this method is called, the subclass implementation should stop loading a request. This could be in response to a cancel operation, so protocol implementations must be able to handle this call while a load is in progress. When your protocol receives a call to this method, it should also stop sending notifications to the client. Subclasses must implement this method.
