Hi, I am trying to figure out how to emulate apple's half screen modal view like in Contacts,Mail,Text Message Apps. I can tell it is a modal view, but I couldn't find anywhere in the docs for half screen dialogue like they do. Any idea? Is it just a full screen with the top half transparent? I basically want to make a half screen modal view with two buttons + a cancel button. How do I pass arguments back to the main view? Thanks.
