視圖的大小自己調(diào)整,代碼只是展示一種思路,細(xì)節(jié)自己把握
//底部標(biāo)識(shí)View
let tipView = JKWorkBottomCell.createView()

tableView.addSubview(tipView)
tableView.addObserver(self, forKeyPath: "contentSize", options: .new, context: nil)
//MARK: 檢測(cè)contentSize
override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {

}
if key == "contentSize" {
let tableViewH = self.tableView?.m_height ?? 0
