copied!<p>The full error is: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key.</p> <p>So I have been trying what other people have been saying with similar problems. I have tried getting rid of every mention of landscapeView in the project, including the Connections in the FIle's Owner in the ViewController_iPhone.xib and then I started fresh by making outlets in the super class ViewController (since I want to use landscapeView and portraitView for iPad also) then I set up connections in ViewController_iPhone.xib and ViewController_iPad.xib to the UIView named Landscape in each respectively, and I still get this error.</p> <p>I'm just starting out in app development so I'm trying to make a template for an app that is supportive of all orientations on both iPhone and iPad. Thanks for any help</p> <p>EDIT: Here is a link to all my app delegate h and m and main.m : <a href="https://stackoverflow.com/questions/9610298/i-am-getting-the-applications-are-expected-to-have-a-root-view-controller-at-the">I am getting the Applications are expected to have a root view controller at the end of application launch error</a></p> <p>EDIT 2: So I also tried to make landscapeView a property of ViewController and I made a setter method in ViewController.m but it still has the same problem.</p>
