In my Mac app, I override and accept certain keystrokes via the keyUp function

  • 0

In my Mac app, I override and accept certain keystrokes via the keyUp function in an NSView, which isn’t meant to accept keystrokes.

When a key is pressed, the keyUp function is called, and I do process the keystroke, without even calling super keyUp:, and everything works, except that it also makes that default ‘doonk’ sound that happens when you press a key somewhere you shouldn’t.

Is there any way to indicate that the keystroke was handled and accepted, and that I don’t need a beep to tell the user it wasn’t?

    I think (but am not 100% certain, it’s been a bit of time since I did this) you also need to override the NSView and/or NSResponder performKeyEquivalent: method. There, you’ll return a YES to indicate to the caller that you did indeed handle the event.

    And that will keep the “dooonk” sound from happening.
