# UIButton.Configuration.CornerStyle

Settings that determine the appearance of the background corner radius.

```
enum CornerStyle
```

## Overview

Use this property to control how the button uses the [`cornerRadius`](/documentation/UIKit/UIBackgroundConfiguration-swift.struct/cornerRadius) property of the button’s [`background`](/documentation/UIKit/UIButton/Configuration-swift.struct/background).

## Topics

### Corner styles

[`UIButton.Configuration.CornerStyle.dynamic`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/dynamic)

A style that adjusts the background corner radius for dynamic type.

[`UIButton.Configuration.CornerStyle.fixed`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/fixed)

A style that uses the background corner radius without modification.

[`UIButton.Configuration.CornerStyle.capsule`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/capsule)

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

[`UIButton.Configuration.CornerStyle.large`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/large)

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

[`UIButton.Configuration.CornerStyle.medium`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/medium)

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

[`UIButton.Configuration.CornerStyle.small`](/documentation/UIKit/UIButton/Configuration-swift.struct/CornerStyle-swift.enum/small)

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