Question

I have installed lately XCode 4+, and since on I get warning message ‘window’ is deprecated.
I have subclassed NSView and called it CentralView and used it to load various views dynamically. I had to subclass the NSView, because there are methods I needed to override.
In other class that controls loading central views I have created following method:

- (IBAction)showUserInfoView:(id)sender{
   NSLog(@"Load new user info page");
   // Try to end editing
   NSWindow *w = [centralView window]; // Here I get warning 'window' is deprecated
   BOOL ended = [w makeFirstResponder:w];
   if (!ended) {
       NSBeep();
       return;
   }
   // Put the view in the box
   NSView *v = [[viewControllers objectAtIndex:0] view];
   NSArray* viewSet = [NSArray arrayWithObject: v];
   [centralView setSubviews: viewSet];

}

As far as I am aware the window method in NSView is up to date. Why do I get message?

What type is centralView? What happens if you say [(NSView*)centralView window]?

It’s possible that the compiler is not finding -[NSView window], but some other -window method which is deprecated. If centralView is declared as an id then the compiler doesn’t know it’s an NSView and has to guess.
