reloadItemsCount 为 0 时崩溃

    pageControl.currentPage = getCurrentIndex() % realItemsCount

getCurrentIndex 方法在阿语环境下就无法实现了

正确的写法应该是这样
private func getCurrentIndex() -> Int {
let point = self.convert(collectionView.center, to: self.collectionView)
let indexPath = self.collectionView.indexPathForItem(at: point)
return indexPath?.item ?? 0
}

下载下来一允许就报错。。。是不是需要配置神马？ Value of type 'NSZone' has no member 'common' 这个错误。。而且不仅是这个。很多语法都没通过。。。

cocoapods init(frame: frame)

示例2的pageControlI 隐藏无效。

在示例二中，如下设置
cycleView2.pageControlIsHidden = true
没有效果，请问如何设置？

delegate 没有 weak处理

如何实现类似知乎日报下拉图片放大的效果？

试了下，在 scrollView.contentOffset.y 改变时，修改 cycleView 的 frame，itemSize，itemZoomScale 都不行呢？

第四种样式, 如果手动滚动的位置会错乱

应该是contentOffset 引起的

自定义cell功能

你好，感谢你提供这么好用的第三方库
我在使用过程中有一个需求需要使用自定义cell，所以我添加了相关方法，希望你可以合并进去，使这个库功能更加完善，我pull给你，你可以检查一下，欢迎指证

在一个页面写了两个cycleView，如何分别处理点击呢

请问支持CocoaPods吗

分页滚动效果与系统分页滚动效果相差较大，建议加上速率判断

滑动过半才会滚动到上一页/下一页，如果滑动较快且没有过半，回弹的速率就会很大，显得很突兀，建议加上速率的过滤条件

ZPageControl在有些场景会不显示

根本原因在于
override public func layoutSubviews() {
super.layoutSubviews()
setupItems()
}
在这个时机,items可能会为空
修改如下
/// page数量
public var numberOfPages: Int = 0 {
didSet {
setupItems()
}
}

数据源刷新问题 reloadItemsCount

if isAutomatic { startTimer() } 应该放在 setItemsCount() 后边。

pagecontrol无法显示

pagecontrol无法显示，cell不能使用xib

动态加载轮播图，一直在第一张

动态加载数据设置轮播图，一直滚动在第一张。采用snapkit布局
fileprivate func currentIndex() -> Int {
let itemWH = scrollDirection == .horizontal ? flowLayout.itemSize.width+itemSpacing : flowLayout.itemSize.height+itemSpacing
let offsetXY = scrollDirection == .horizontal ? collectionView.contentOffset.x : collectionView.contentOffset.y
// contentOffset changes /(ㄒoㄒ)/~~ ??????????
if itemWH == 0 { return 0 }
let index = round(offsetXY / itemWH)
return Int(index)
}
这段代码返回的一直是0

support swift 5

Whether planned adaptation swift 5?
