# IKFilterUIView

Input parameters for filtering core image filters.

```
class IKFilterUIView
```

## Overview

The `IKFilterUIView` class provides a view that contains input parameter controls for a Core Image filter (<doc://com.apple.documentation/documentation/CoreImage/CIFilter-swift.class>). You need to use this class when providing a user interface for a custom filter. The class creates a view that has an object controller for the given filter. It also retains the filter.
