Changing the starting view on an existing project Xcode

I have an old project in Xcode and I want to c开发者_JAVA技巧hange the RootViewController files (.m, .h, .xib - a TableViewController) with a normal ViewController! Is it possible or I must restart a new project and import the old files?

Depends on how your project is set up. But you may just need to include and change the controller linked to by the window and app delegate in your MainWindow.xib file.
