CPInfiniteBanner是一个循环播放的组件，可以左右无缝滑动和自动切换图片。
CPInfiniteBannerView *banner = [[CPInfiniteBannerView alloc]initWithContainerView:self.view responseBlock:nil];
banner.frame = CGRectMake(20, 30, self.view.frame.size.width-40, 90);
banner.placeHolder = [UIImage imageNamed:@"3.jpg"];
banner.duration = 3.0;
banner.imageArray = [NSMutableArray arrayWithArray:array];
目前都使用cocoapods安装，在Podfile中加入
pod 'CPInfiniteBanner', '~> 0.2.1'
3个imageView放在scrollview上，左右2个imageview用于过渡，借助scrollview的deleagte来实现轮播逻辑。也可以参考别的实现方式 https://github.com/leichunfeng/LCFInfiniteScrollView
