Implement a keyboard click sound, lost

Everyone on this site has been very helpful on my schooling of iOS programming, but I've run into a brick wall with a very simple feature. I've found Apples documentation on implementing the factory keyboard click sound upon a button touch, but what Im not getting is the "creating a sub lass of UIView" part. I have a very basic calculator that I've built, the buttons are made of standard Round Rect's that I want to make the simple click sound. So Apple says:Adopting the UIInputViewAudioFeedback Protocol Perform the following three steps to adopt the UIInputViewAudioFeedback protocol:

In your Xcode project, create a subclass of the UIView class. In the header file, indicate that the subclass conforms to the UIInputViewAudioFeedback protocol, as follows: @interface KeyboardAccessoryView : UIView { }

Now I am using the standard UIViewController tied to a xib with all my buttons. Am i to: Create New File, name it as a subclass of UIView, JUST so i can implement this sound? That doesn't make sense to me, and if this is really amateur stuff I apologize, but I'm learning from many different places. Thanks in advance.

You have to set your custom input view as the inputView property of the object that is supposed to be the first responder (For example, a UITextField instance), and the inputView(your custom input view) must conform to the UIInputViewAudioFeedback protocol. And to actually play a click sound: [[UIDevice currentDevice] playinputClick].

For example:

@interface MyCalculatorDisplay : UIView
// ...
@end

@interface MyCustomKeyboard : UIView <UIInputViewAudioFeedback>
// ...
@end

// Then, somewhere in your controller:

MyCustomKeyboard *keyboard = [MyCustomKeyboard new];

MyCalculatorDisplay *display = [MyCalculatorDisplay new];

display.inputView = keyboard;
