# isRefreshing

A Boolean value indicating whether a refresh operation is in progress.

```
var isRefreshing: Bool { get }
```

## Discussion

The default value of this property is `NO`. When the user triggers a refresh,
this property automatically becomes `YES`. Call [`endRefreshing()`](/documentation/AppKit/NSRefreshController/endRefreshing()) when your
refresh operation completes to reset this property to `NO`.
