Changing the name of an IBACTION now gives an uncaught exception error

Question

OK this one is hopefully really simple

I thought I had it figured out once but can't remember what I did

In any app I go in and create a connection to a button or whatever and I give it a name like "PressThisButtonWhenDone"

this is all good and it works fine

BUT

I then want to change the name to "PressThisButtonWhenFinished"

so I delete the old action and create the new one with this name and I go into the .m file to remove the old action Xcode put in place automatically for me and place any code I had in the old method in the new properly named one.

I then build the project and it goes just fine the app comes up and I use all the other functions just fine and then I hit the Button associated with "PressThisButtonWhenFinished" and I get something along these lines...

This is the old button name and I cannot locate it anywhere to remove it I tried doing a clean not sure if that would do anything and it did nothing How do I eliminate this error

As it turns out there was still a connection to the old name and that was the reason for the error.By going to the connections manager I found the new connection was there and so was the old one. I deleted the old one and it works fine now. I knew it would be a simple fix.
