在xcode5下设置两个viewController跳转——关键是禁用arc

1、禁用arc

2、然后使用如下代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    GuideViewController *myGuideVC = [[GuideViewController alloc]initWithNibName:@"GuideViewController" bundle:nil];
    ADViewController *myADVC = [[ADViewController alloc]initWithNibName:@"ADViewController" bundle:nil];
    
   [self.window addSubview:myADVC.view];
   [self.window addSubview:myGuideVC.view];   //用户在此页面点击确定，则会[self removeSuperView] ,展现 myADVC.view

[self.window makeKeyAndVisible]; return YES;
}
