Connect object in .xib to existing IBAction

Question

I am quite new to iOS Programming.

This is my question:

I want to connect a new object to an existing IBAction method. For example, I want to buttons to perform the same function.

But when I "control-drag" it, it will always ask me to insert as a new method. How can I add to the existing one instead of creating a new one?

In your xib editor, you can see the File's Owner. Just right click the button to see the black popup as shown in the image below. Then drag the empty dot to the File's Owner tab and release the drag action. You'll see a popup of all existing IBActions. Select the one you want and it'll be added as a selector to your button. You can do this for as many buttons as you want.
