Hi guys I'm trying to paste text right into where the cursor currently is. I have been trying to do what it says at: - http://dev.ragfield.com/2009/09/insert-text-at-current-cursor-location.html

The main deal is that I can't just go textbox1.text (etc) because the textfield is in the middle of a custom cell. I want to just have some text added to where the cursor is (when I press a custom key on a keyboard).

-I just want to paste a decimal into the textbox...

The error I get is:

2010-05-15 22:37:20.797 PageControl[37962:207] * -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10 2010-05-15 22:37:20.797 PageControl[37962:207] Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[MyDetailController paste:]: unrecognized selector sent to instance 0x1973d10'

Note: I have access to the textfield tag (if that helps?)

I'm a little past the beginner stage in objective-c, but still not great. My code is currently below, and at https://gist.github.com/d634329e5ddf52945989

Thanks all.
