iPhone - dealloc subview UIViewController when removeFromSuperview

Question

I have several buttons on my main UIViewController (main menu) that creates and adds a subview UIViewController on top of the main menu. When I remove the subview the memory from that controller is not released. How can I release that subviews memory instantly?

Does anyone have an example? This would solve all my problems! Thanks in advance.

Here is how I add a subview

if((UIButton *) sender == gameClassicBtn) {
     GameClassic *gameClassicController = [[GameClassic alloc] 
              initWithNibName:@"GameClassic" bundle:nil]; 
     self.gameClassic = gameClassicController;
     [gameClassicController release]; 
     [self.view insertSubview:gameClassicController.view atIndex:1];
    }

Based on the code you provided there could be at least two places the UIViewController is being retained - one by the view heirarchy (self.view) and the other by a member variable (self.gameClassic). It sounds like you're only releasing the view heirarchy reference but not the member variable. If you release the latter does it deallocate the UIViewController?
