Usage

初始化

创建频道选择器只需要三个参数：代理，是否缓存用户操作（默认缓存），数据源（网络获取到后再赋值即可）

private lazy var channelSelector: YDChannelSelector = {
    let cv = YDChannelSelector()
    cv.dataSource = self
    cv.delegate = self
    // 是否支持本地缓存用户功能
//        cv.isCacheLastest = false
    return cv
}()

数据源

SelectorItem中有三个属性 channelTitle即为频道标题 isFixation 是否是固定栏目 rawData ** 原始数据模型或者字典皆可 **

public protocol YDChannelSelectorDataSource: class {
    func numberOfSections(in selector: YDChannelSelector) -> Int
    func selector(_ selector: YDChannelSelector, numberOfItemsInSection section: Int) -> Int
    func selector(_ selector: YDChannelSelector, itemAt indexPath: IndexPath) -> SelectorItem
}
.........

弹出

直接使用UIViewController的方法present即可

present(channelSelector, animated: true, completion: nil)

代理

// 数据源发生变化
func selector(_ selector: YDChannelSelector, didChangeDS newDataSource: [[SelectorItem]]) {
    print(newDataSource.map { $0.map { $0.channelTitle! } })
}

// 用户退出操作时
func selector(_ selector: YDChannelSelector, dismiss newDataSource: [[SelectorItem]]) {
    print(newDataSource.map { $0.map { $0.channelTitle! } })
}

// 用户选中新频道时
func selector(_ selector: YDChannelSelector, didSelectChannel channelItem: SelectorItem) {
    print(channelItem.channelTitle!)
}
