Loading a new view before the old one iphone sdk - iphone

Question

Probably just a simple question, but ive been building a little puzzle game and no decided i could do with a menu for it. Ive created the menu no problem i just cant get it to show before the puzzle. Ive tried changing the code in the appdelegate but its not liking it.
slider appdelegate.h
#import <UIKit/UIKit.h>
#class SliderViewController;
#class MainMenu;
#interface SliderAppDelegate : NSObject <UIApplicationDelegate> {
UIWindow *window;
MainMenu *viewController1;
}
#property (nonatomic, retain) IBOutlet UIWindow *window;
#property (nonatomic, retain) IBOutlet SliderViewController *viewController;
#property (nonatomic, retain) IBOutlet MainMenu *viewController1;
#end
Slider appdelegate.m
#import "SliderAppDelegate.h"
#import "SliderViewController.h"
#implementation SliderAppDelegate
#synthesize window;
#synthesize viewController;
#synthesize viewController1;
#pragma mark -
#pragma mark Application lifecycle
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// Add the view controller's view to the window and display.
[self.window addSubview:viewController1.view];
[self.window makeKeyAndVisible];
return YES;
}
But doing that throws out an error:
error: request for member 'view' in
something not a structure or union
I know its probably a stupid question but could anyone help please.

You need to import that class and make alloc the object first see this
Slider appdelegate.m
#import "SliderAppDelegate.h"
#import "SliderViewController.h"
#import "MainMenu.h"//change here
#implementation SliderAppDelegate
#synthesize window;
#synthesize viewController;
#synthesize viewController1;
#pragma mark -
#pragma mark Application lifecycle
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
viewController = [[[MainMenu alloc] initWithNibName#"MainMenu" bundle:nil] autorelease]; // and here
[self.window addSubview:viewController1.view];
[self.window makeKeyAndVisible];
return YES;
}
