// 数据源
let pictures: [String] = ["http://pic29.nipic.com/20130512/12428836_110546647149_2.jpg", "picture2", "picture3", "picture4", "picture5", "http://pic29.nipic.com/20130512/12428836_110546647149_2.jpg", "picture7"]
// 初始化
let cyclePictureView: JCyclePictureView = JCyclePictureView(frame: CGRect(x: 0, y: 20, width: self.view.frame.width, height: 150), pictures: pictures)
// 标题
cyclePictureView.titles = ["标题1", "标题2", "标题3", "标题4", "标题5", "标题6", "标题7"]
// 滚动方向
cyclePictureView.direction = .left
// 自动滚动时间
cyclePictureView.autoScrollDelay = 3
// pageControl 位置
cyclePictureView.pageControlStyle = .center
// 默认显示图
cyclePictureView.placeholderImage = #imageLiteral(resourceName: "picture1")
// 高亮圆点
cyclePictureView.pageControl.currentPageIndicatorTintColor
cyclePictureView.pageControl.currentPageIndicatorImage
// 默认圆点
cyclePictureView.pageControl.pageIndicatorTintColor
cyclePictureView.pageControl.pageIndicatorImage
// 点击回调
cyclePictureView.didTapAtIndexHandle = { index in
print("点击了第 \(index + 1) 张图片")
}
self.view.addSubview(cyclePictureView)
// 自定义 cell
cyclePictureView.register([CustomCell.self], identifiers: ["CustomCell"]) { (collectionView, indexPath, picture) -> UICollectionViewCell in
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCell
if picture.hasPrefix("http") {
cell.imageView.kf.setImage(with: URL(string: picture), placeholder: nil)
} else {
cell.imageView.image = UIImage(named: picture)
}
cell.label.text = "自定义 cell"
cell.label.textColor = UIColor.white
return cell
}
// 自定义 nib cell
cyclePictureView.register(<#T##nibs: [UINib?]##[UINib?]#>, identifiers: <#T##[String]#>, customCellHandle: <#T##JCyclePictureViewCustomCellHandle##JCyclePictureViewCustomCellHandle##(UICollectionView, IndexPath) -> UICollectionViewCell#>)示例代码见ViewController.swift
