- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [self initUserGuidePage]; //用户引导页
}

// 用户引导页
-(void)initUserGuidePage{
    if (![[NSUserDefaults standardUserDefaults] boolForKey:BOOLFORKEY]) {
        [[NSUserDefaults standardUserDefaults] setBool:YES forKey:BOOLFORKEY];
        //静态引导页
        [self setStaticGuidePage];
    }
}
// 设置APP静态图片引导页
- (void)setStaticGuidePage {
    NSArray *imageNameArray = @[@"one",@"two",@"three"];
    DHGuidePageHUD *guidePage = [[DHGuidePageHUD alloc] dh_initWithFrame:[UIScreen mainScreen].bounds imageNameArray:imageNameArray buttonIsHidden:NO];
    guidePage.slideInto = YES;
    AppDelegate * del = (AppDelegate *)[UIApplication sharedApplication].delegate;
    [del.window addSubview:guidePage];
}

在使用中只需要在跟视图的viewDidLoad里调用即可，调用方法如下：

 //用户引导页
    [(AppDelegate*)[UIApplication sharedApplication].delegate initUserGuidePage];
