ios轮播广告框-SDCycleScrollView用法

1. 先去github下载lib库，代码引入项目内
   https://github.com/gsdios/SDCycleScrollView

2. 加入协议
   @interface FirstViewController ()

3. 加入代码：

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.view.backgroundColor = [UIColor colorWithRed:0.98 green:0.98 blue:0.98 alpha:0.99];
    UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"005.jpg"]];
    backgroundView.frame = self.view.bounds;
    [self.view addSubview:backgroundView];
    
    UIScrollView *demoContainerView = [[UIScrollView alloc] initWithFrame:self.view.frame];
    demoContainerView.contentSize = CGSizeMake(self.view.frame.size.width, 1200);
    [self.view addSubview:demoContainerView];
    
    self.title = @"轮播Demo";

    
    // 情景一：采用本地图片实现
    NSArray *imageNames = @[@"h1.jpg",
                            @"h2.jpg",
                            @"h3.jpg",
                            @"h4.jpg",
                            @"h7" // 本地图片请填写全名
                            ];
    
    // 情景二：采用网络图片实现
    NSArray *imagesURLStrings = @[
                           @"https://ss2.baidu.com/-vo3dSag_xI4khGko9WTAnF6hhy/super/whfpf%3D425%2C260%2C50/sign=a4b3d7085dee3d6d2293d48b252b5910/0e2442a7d933c89524cd5cd4d51373f0830200ea.jpg",

                           ];
    
    // 情景三：图片配文字
    NSArray *titles = @[@"新建交流QQ群：185534916 ",
                        @"感谢您的支持，如果下载的",
