| ### Interactive background views |
| |
| Scenario: you've added a background image to your App Bar and you'd now like to be able to tap the |
| background image. |
| |
| This is not trivial to do with the App Bar APIs due to considerations being discussed in |
| [Issue #184](https://github.com/material-components/material-components-ios/issues/184). |
| |
| The heart of the limitation is that we're using a view (`headerStackView`) to lay out the Navigation |
| Bar. If you add a background view behind the `headerStackView` instance then `headerStackView` will |
| end up eating all of your touch events. |
| |
| Until [Issue #184](https://github.com/material-components/material-components-ios/issues/184) is resolved, our recommendation for building interactive background views is the following: |
| |
| 1. Do not use the App Bar component. |
| 2. Create your own Flexible Header. Learn more by reading the Flexible Header |
| [Usage](../../FlexibleHeader/#usage) docs. |
| 3. Add your views to this flexible header instance. |
| 4. Create a Navigation Bar if you need one. Treat it like any other custom view. |
