buttonClick method question

I am trying to programmatically invoke a routine that I've written to handle a button press.

I see reference to the buttonClick property but when I try using it I get an error.

Where else would I need a buttonClick property if not with a UIButton?

I tried to write the code in a block but that didn't work. The "scope" was wrong.

In BASIC I'd just call a subroutine.

Here's what I'm trying to do - along with the error message. I would appreciate some help please.

_locButton.performClick(); property ‘performClick’ not found on object of type “UIButton”
