/**
 加载引导页

- (void)loadGuidePage {
    // 基础配置
    self.window = [[UIWindow alloc] initWithFrame:SCREEN_RECT];
    self.window.backgroundColor = [UIColor whiteColor];
    
    viewController = [[UIViewController alloc] init];
    viewController.view.frame = self.window.bounds;
    viewController.view.backgroundColor = [UIColor whiteColor]; // [UIColor generateDynamicColor:[UIColor whiteColor] darkColor:[UIColor blackColor]];
    self.window.rootViewController = viewController;
    [self.window makeKeyAndVisible];
    
    // 数据源
    NSArray *arrGuidePage = @[@"guidePageFirst", @"guidePageSecond", @"guidePageThird"]; // , @"guidePageFourth"
    // 组件初始化
    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:viewController.view.bounds];
    scrollView.backgroundColor = [UIColor lightGrayColor];
    scrollView.delegate = self;
    scrollView.contentSize = CGSizeMake(arrGuidePage.count * SCREEN_WIDTH, self.window.frame.size.height);
    scrollView.pagingEnabled = YES;
    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.showsVerticalScrollIndicator = NO;
    [viewController.view addSubview:scrollView];
    // 组件设置
    for (NSInteger i = 0; i < arrGuidePage.count; i++) {
        UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(i * SCREEN_WIDTH, 0, SCREEN_WIDTH, SCREENH_HEIGHT)]; // self.window.frame.size.height
        imageView.userInteractionEnabled = YES;
        imageView.image = [[UIImage imageNamed:[NSString stringWithFormat:@"%@", arrGuidePage[i]]] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
        [scrollView addSubview:imageView];
        
        if (i == arrGuidePage.count - 1) {
            UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
            btn.frame = CGRectMake(i * SCREEN_WIDTH + 30, SCREEN_HEIGHT - 120, SCREEN_WIDTH - 30 * 2, 50);
            btn.backgroundColor = [UIColor colorWithHexString:@"#ff685e"];
            [btn setTitle:@"立即体验" forState:UIControlStateNormal];
            [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
            btn.layer.cornerRadius = 4.f;
            btn.layer.masksToBounds = YES;
            btn.layer.borderWidth = 1;
            btn.layer.borderColor = [UIColor colorWithHexString:@"#ff685e"].CGColor;
            btn.alpha = 0;
            [UIView animateWithDuration:3.f animations:^{
                btn.alpha = 1;
            }];
            [btn addTarget:self action:@selector(pushHomePage) forControlEvents:UIControlEventTouchUpInside];
            [scrollView addSubview:btn];
        }
    }
}

- (void)pushHomePage {

}
