iOS开发启动页引导图

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];

}
