Answer 1

Each time the button is clicked, you make a new gameViewController and push it into self.navigationController.

You want to not make a new one each time.

Answer 2

set up gameViewController as a property in the .h

@property(nonatomic,retain) GameViewController *gameViewController;

and in the .m

@synthesize gameViewController

then use the property when assigning

self.gameViewController = [[GameViewController alloc] initWithNibName:@"GameViewController" bundle:nil];

and release at the end

[self.navigationController pushViewController:gameViewController animated:YES];
[gameViewController release];
