Objective-C warnings - what did I missing or what is wrong?

I am new at programming and now I am writing an application with 6 views. My program starts not really, I only see the background - the default.png - and then the prpgramm crashes but I see the default- image. In addition i have problems understanding the warnings I recieve, it is like a new language. If you know a book or a page how to decode this warnings it would be very helpful too

You've created a view controller inside a NIB but you've failed to give it a view. You should do that by putting a view into the NIB and control-clicking from the view controller to the view and then selecting the view outlet from the pop-up that appears — i.e. the normal way of connecting things in the interface designer.

The error you're seeing is an exception raised deliberately by UIViewController because it doesn't know how to proceed without a view. The stuff below that is the stack trace; if the problem were in your own code you could use that to look into what calling pattern got you into the invalid state. As it's in a bunch of internal stuff for which the logical structure is documented but the internal implementation is private you should just ignore it.

Go back through whatever text you are using to learn about how to create view controllers and XIB files and figure out what step you missed.

Looking at first line of your crash report, reason for crash is quite obvious:

loaded the "TestTestViewController" nib but the view outlet was not set.
