NSWindow closing and controlling issues in Mac OS X

I met the issues of NSWindow regarding closing it when the application starts. There are plenty of examples, however, I can not get the proper effect, perhaps I missing something.

Firstly, in many examples there is the recommendation to use "[self window]" but I get the error like "No visible @interface for 'ViewController' declares the selector 'window'".

Then I use the round way: "[[self view] window]". Anyway, the window is not closed after the execution of the code:

NSWindow *win = [[self view] window];
[win performClose:self];

or

NSWindow *win = [[self view] window];
[win close];

The next one also does not give any results as I expect, according to the documentation:

[win orderOut:self];

The code compiles but I can see the window. Of course, I tried:

NSLog(@"%@", [win.windowController windowShouldClose:self] ? @"YES" : @"NO" );

It outputs "NO", so, it means that the window, which appear when I run my application, cannot be closed? Is there any way how to work around it? Why I cannot control that main window following the way the documentation suggests?

I checked for the import "#import AppKit/AppKit.h;" as well.

All of this suggests that win is nil. The view of your view controller is not in a window.
