# UIButtonConfigurationCornerStyle

Settings that determine the appearance of the background corner radius.

```
enum UIButtonConfigurationCornerStyle : NSInteger;
```

## Overview

Use this property to control how the button uses the [`cornerRadius`](/documentation/UIKit/UIBackgroundConfiguration-c.class/cornerRadius) property of the button’s [`background`](/documentation/UIKit/UIButtonConfiguration/background).

A style that uses the background corner radius without modification.

[`UIButtonConfigurationCornerStyleCapsule`](/documentation/UIKit/UIButtonConfigurationCornerStyle/UIButtonConfigurationCornerStyleCapsule)

A style that ignores the background corner radius and uses a corner radius that generates a capsule.

[`UIButtonConfigurationCornerStyleLarge`](/documentation/UIKit/UIButtonConfigurationCornerStyle/UIButtonConfigurationCornerStyleLarge)

A style that ignores the background corner radius and uses a large system-defined corner radius.

[`UIButtonConfigurationCornerStyleMedium`](/documentation/UIKit/UIButtonConfigurationCornerStyle/UIButtonConfigurationCornerStyleMedium)
