Black screen in iphone simulator

ok, like an idiot, in Interface Builder i started messing around with the connections and deleted a few connections (ie. delegates, controllers) and now when i build and run, all i get is a black screen. I know you cant see my code but could someone guess at what i would 开发者_开发技巧need to reinstate to get a working app back!

Thanks

First guess would be that the window outlet is not connected. Then I'd check all the other connections that should be there.

Oh, and use a source control management system, i.e. git. :-)
