1.下面的代码写在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

2. 引进附件里的类， 记得改类里的图片啊啥的（http://files.cnblogs.com/files/godlovexq/UDP.zip）

if (![[NSUserDefaults standardUserDefaults] boolForKey:@"dongqiangfei"])

    {

        //是第一次启动

        [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"dongqiangfei"];

        GuideViewController *guide = [[[GuideViewController alloc] init] autorelease];

        self.window.rootViewController = guide;//让动画的视图作为主视图

        [guide.button addTarget:self action:@selector(setupAppDelegate) forControlEvents:UIControlEventTouchUpInside];

    }else{

        //不是第一次

        [self setupAppDelegate];

    }
