The UIInputViewAudioFeedback protocol defines a single property for enabling a custom input or keyboard accessory view to play standard keyboard input clicks.

Implement this protocol in your custom subclass of UIView that you associate with your custom input Nib file. For more information, see Text, Web, and Editing Programming Guide for iOS.

Implementation of this protocol is optional but expected.

Return YES to enable input clicks by way of the playInputClick method, or NO to disable input clicks. The value is NO by default.

Discussion

In your custom subclass of UIView, implement this property as a getter method. Return YES to enable input clicks in your custom input or keyboard accessory view, as follows:
