| ### MDCProgressView |

| #### -accessibilityValue |
| |
| Like UIProgressView, MDCProgressView's `accessibilityValue` is based on the current value of the ProgressView's |
| `progress` property. Also like UIProgressView, this `accessibilityValue` takes the form of a whole number |
| percentage. To ensure the same behavior between the two classes, the MDCProgressView class has a static |
| UIProgressView that instances query for its `accessibilityValue` whenever they need to provide their own. |
| |
| The ProgressView announces a new `accessibilityValue` whenever its `progress` changes if VoiceOver is on. |
