本文介绍了在iOS应用中设置启动画面及使用导航控制器进行页面切换的方法。通过自定义UIApplicationDelegate的didFinishLaunchingWithOptions方法，实现了应用启动时的初始化设置，并通过UINavigationController推动ViewController实现页面的动画切换。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.
    self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController" bundle:nil] autorelease];
    //self.window.rootViewController = self.viewController;
   
    [self.window addSubview:self.viewController.view];
    UINavigationController * navigationController = [[UINavigationController alloc]initWithRootViewController:self.viewController];
    [self.window addSubview:navigationController.view];
     [self.window makeKeyAndVisible];
    return YES;
}


- (IBAction)btnPress:(id)sender
{
    ViewController *viewc = [[ViewController alloc]init];
    [self.navigationController pushViewController:viewc animated:YES];
}
