| ### Customizing elevation |
| |
| The elevation of a button can be changed for a given control state using `setElevation:forState:`. |
| |
| See the [Material Design shadow guidelines](https://material.io/guidelines/what-is-material/elevation-shadows.html) for a detailed |
| overview of different shadow elevations. |
| |
| For example, to make a button elevate on tap like a floating action button: |
| |
| <!--<div class="material-code-render" markdown="1">--> |
| #### Swift |
| ```swift |
| button.setElevation(6, for: .normal) |
| button.setElevation(12, for: .highlighted) |
| ``` |
| |
| #### Objective-C |
| |
| ```objc |
| [button setElevation:6 forState:UIControlStateNormal]; |
| [button setElevation:12 forState:UIControlStateNormal]; |
| ``` |
| <!--</div>--> |
