Tabbed application troubles in xcode

I am working with my first tabbed application in xcode. I am just testing with some stuff since I'm relatively new to programming. I am just using the 2 views already put into the template. I am putting a slider into the first view and am going to attach it to a text box with numbers. But that isn't the problem! This is probably really stupid and simple, but when i run the application just to see the stuff on the simulator, it is just showing a black screen. NO CLUE WHY! But its killing me and would love some help!

I did end up starting a new project. Weird that the black screen showed up.. not really sure why that error was popping up.. I'm not really that knowledgable about the different errors and bugs that a program can have yet! Getting closer though!

You are not suppose to make connections in AppDelegate. You should use a ViewController for each class. I.E. FirstViewController, SecondViewController. AppDelegate is usually only used for calling save/restore messages.

You are getting the error because the storyboard view is assuming you are assigning it to the correct view. When you create the storyboard say you named it TestApp. Then, you should have a few classes. TestAppDelegate, TestAppDelegateFirstViewController, TestAppDelegateSecondViewController. Or something along those lines. FirstViewController should connect to the first view on the tab view. The Second should attach to the second.

AppDelegate is almost never used for UI. I would suggest you find a book on the matter. I'll suggest "iOS Programming. The Big Nerd Ranch Guide". It helped me a lot when I started.
