| ### Supported UIBarButtonItem properties |
| |
| The following properties are taken into consideration when `items` is set and the corresponding |
| buttons are created. |
| |
| Changes made to properties marked (observed) will be reflected in the corresponding buttons. |
| |
| - `title` (observed) |
| - `image` (observed) |
| - `enabled` (observed) |
| - `width` |
| - `target` |
| - `action` |
| - `titleTextAttributesForState:` |
| |
| TODO(featherless): File bugs to observe the rest of the properties. |
| |
| Note: in order to make Button Bar reflect changes to not-observed properties you must clear the |
| MDCButtonBar instance's `items` property and reset it, like so: |
| |
| <!--<div class="material-code-render" markdown="1">--> |
| #### Swift |
| ```swift |
| actionItem.target = <some other target> |
| |
| let items = buttonBar.items |
| buttonBar.items = nil |
| buttonBar.items = items |
| ``` |
| |
| #### Objective-C |
| |
| ```objc |
| actionItem.target = <some other target>; |
| |
| NSArray *items = buttonBar.items; |
| buttonBar.items = nil; |
| buttonBar.items = items; |
| ``` |
| <!--</div>--> |
