_mainView = [[_window contentView] retain]; 
...
[_window release];
_window = nil;
return _mainView;

Now you are the owner of highest accessible NSView object in the window’s view hierarchy. 

NSView  *mainView = [[window1 contentView] retain]; 
[window1 release];
window1 = nil;
[window setContentView:mainView];
