interpretKeyEvents: and insertText: under 10.8


  • Subject: interpretKeyEvents: and insertText: under 10.8
  • From: Rob McBroom <email@hidden>

The documentation for `interpretKeyEvents:` says:

    The input manager responds to the request by sending insertText: and doCommandBySelector:messages back to the invoker of this method.

What I'm seeing is that when I call `[self interpretKeyEvents:[NSArray arrayWithObject:theEvent]]` from `keyDown:`, it's sending `insertText:` to a different object …but only once. For subsequent keystrokes, the message is sent to the same object.

`interpretKeyEvents:` should *always* send `insertText:` back to the same object it was called on, right? This appears to be the case under 10.7, but not under 10.8.

The documentation for `insertText:` is a little less clear:

    The NSResponder implementation simply passes this message to the next responder, or beeps if there is no next responder.

But I've verified that the first time `insertText:` is called, `self` and first responder are not the same object.

So is this a bug, or am I misunderstanding something? Thanks.
