Multiple View App shows Blank Screen in Simulator
- by Brett Coburn
Hello;
I am developing a simple app that first shows a menu screen, and when a button is pressed, a game screen appears. I was able to develop the game screen without any issues, but when I changed the code to first display the menu, the simulator showed a blank screen.
I've read all the articles on connecting views with IB but I can't figure this out.
Any help would be appreciated.
This is my code:

#import <UIKit/UIKit.h>
@class MenuViewController;
@interface Pong_Multiple_ViewAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
MenuViewController *navigationController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet MenuViewController *navigationController;
@end

@implementation Pong_Multiple_ViewAppDelegate
@synthesize window;
@synthesize navigationController;
- (void)application:(UIApplication *)application{
// Override point for customization after application launch
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
}
- (void)dealloc {
[navigationController release];
[window release];
[super dealloc];
}
@end

@interface MenuViewController : UIViewController {
GameViewController *gameViewController;
IBOutlet UIButton *gameButton;
}
@property(nonatomic, retain) GameViewController *gameViewController;
@property(nonatomic, retain) UIButton *gameButton;
-(IBAction)switchPage:(id)sender;
@end
//

@implementation MenuViewController
@synthesize gameViewController;
@synthesize gameButton;
-(IBAction)switchPage:(id)sender{
if (self.gameViewController==nil) {
GameViewController *gameView = [[GameViewController alloc]initWithNibName:@"GameView" bundle:[NSBundle mainBundle]];
self.gameViewController= gameView;
[gameView release];
}
[self.navigationController pushViewController:self.gameViewController animated:YES];
}
....
@end
My code also includes classes: GameViewController.h, GameViewController.m, and nib files: MenuView.xib, and GameView.xib
Thanks,
B
