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];
    }
