Error using objects and outlets in Views

I have declared an UIViewController to show more views because my program needs multiple views. OK everything is ok and another pages will load when i need but when i add outlets (in vies) to Files Owner (for example a button). application wont work, and will quit immediately.

I have described my issue complete in this video: http://www.youtube.com/watch?v=vsx-72TP2m8

Thanks and Best regards

Solution

  • Definitely the best described question I have seen so far!

    The problem is that you are trying to force a UIViewController to load a XIB whose file owner is of type SOME. Although SOME inherits UIViewController, the outlet connections (let's say variables) belong to SOME. So the runtime tries to connect the outlets from the XIB, to the UIViewController instance. This is why you are getting an NSUnknownKeyException.

    The best thing to do is:

    SOME homePage = new SOME();

    instead of UIViewController homePage = new UIViewController("SOME", null);.

    Remember, it is SOME's constructor (nibName, bundle) you need, not UIViewController's.
