Hi koko,
This could be anything from "the view is added to the wrong subview" to "the
view has a frame that moves it outside of its' parents bounds" to "the view is
visible but does not draw anything."
Two powerful tools that will help you with debugging:
- Run with NSShowAllViews set to YES
- Use the _subtreeDescription method to get a list of all your views and where
they are.
A web search will show you how to do either of those if you're not sure.
Hope that helps.
