Missing view window on Interface builder

I have an issue with a certain XIB file. When I open it from the xcode using interface builder I get all the windows besides the screen preview one (view window).

I tried all sorts of solutions proposed here like double clicking the view object, closing and relaunching with no success. I am worried that 开发者_如何学Pythonit is lost. Please help.

Thanks,

Found the answer for this with a little help of a friend.

Double click the VIEW item from the XIB window (where you have the FILE'S OWNER and the FIRST RESPONDER).

I know it might be a novice issue but since I lost some time and nerves on this I hope ti might help others.
