I have an `UITableView` that is loaded from two custom cell `xib` files.
The second one contains an `UIButton`.

But since i've added the custom class for `xib` - it has its own actions and functions, which i cannot access from `ViewController`.

My goal is to apply some action on `UIButton` when the custom cell is loaded in the tableview.

My function is defined in ViewController (because all variables are there) and my `UIButton` action is defined in Custom class for `xib`. 

How do i connect one to another?

Thank you
