| ### MDCPresentationController Accessibility |
| |
| As MDCPresentationController is responsible for the presentation of your |
| custom view controllers, it does not implement any accessibility |
| functionality itself. |
| |
| #### `-accessibilityPerformEscape` Behavior |
| |
| If you intend your presented view controller to dismiss when a user |
| in VoiceOver mode has performed the escape gesture the view controller |
| should implement the accessibilityPerformEscape method. |
| |
| ``` |
| - (BOOL)accessibilityPerformEscape { |
| [self.presentingViewController dismissViewControllerAnimated:YES completion:NULL]; |
| return YES; |
| } |
| ``` |
