cocoa: how to create a custom view by IB?
===

I want to create a custom view, say MyView, which is only containing a button and print out "hello my view" when I click it.  When next time I want to use it, I just need to add a custom view to window from IB, add MyView.m into project and set the class of custom view to MyView.

My question is :

1. I want to use IB to set the appearance of MyView, but I don't know how to get the corresponding view file : MyView.m in order to use the MyView.m file next time.
