可展开型预览TableView，开放接口，完全自由定制

虽然最近很忙，天天被html+css虐待，但是在许多朋友的压力下，最近还是抽空完成了一个新轮子ZYThumbnailTableView。以下严格按照小学语文老师教的方式排版：

Summary：

tableView的皮肤，类似一个小型app的强大交互心脏，四肢高度解耦高度自由定制，每个cell其实都是一个业务的缩略view，原谅我语文不太好不懂表达，这样的缩略view下文就叫做thumbnailView，可以根据上下手势展开更多的功能视图块，这些视图块已经开放了接口，支持使用者自己diy提供创建，同时接口中带的参数基本满足使用者需要的交互，当然tableviewCell也是完全自由diy的，规矩，先上效果图。

工作特点：tableViewCell充当一个缩略内容的容器，初始内容展示局限于cellHeight，当cell被点击后，根据缩略view内容重新计算出完整的高度，装入另外一个容器中完整展示出来，并且可以上下拖拽扩展出上下功能视图。
自由定制：看见的除了功能以外，全部视图都开放接口灵活Diy，tableViewCell，头部扩展视图(topView)，底部扩展视图(bottomView)都是自己提供。
使用简单：只需要把自己的tableViewCell，topView，bottomView配置给ZYThumbnailTableViewController对象。

profile(可略过):

Block:
- ConfigureTableViewCellBlock = () -> UITableViewCell?
- UpdateTableViewCellBlock = (cell: UITableViewCell, -indexPath: NSIndexPath) -> Void
- CreateTopExpansionViewBlock = (indexPath: NSIndexPath) -> UIView
- CreateBottomExpansionViewBlock = () -> UIView

Define:
- NOTIFY_NAME_DISMISS_PREVIEW
通知名(让展现出来的thumbnailView消失)
- MARGIN_KEYBOARD_ADAPTATION
自动处理键盘遮挡输入控件后，键盘与输入控件保持的间距（自动处理键盘遮挡事件使用ZYKeyboardUtil实现
- TYPE_EXPANSION_VIEW_TOP
处理展开抖动事件时，顶部扩展控件的标识
- TYPE_EXPANSION_VIEW_BOTTOM
处理展开抖动事件时，底部扩展控件的标识

Property:
开放：
- tableViewCellHeight
- tableViewDataList
- tableViewCellReuseId
- tableViewBackgroudColor
- keyboardAdaptiveView 你自定义控件里如果有希望不被键盘遮挡的输入控件，赋值给他，会帮你==自动处理遮盖事件==
私有：
- mainTableView
- clickIndexPathRow 记录被点击cell的indexPath row
- spreadCellHeight 存储thumbnailCell展开后的真实高度
- cellDictionary 存储所有存活中的cell
- thumbnailView 缩略view
- thumbnailViewCanPan 控制缩略view展开(扩展topView&buttomView)手势是否工作
- animator UI物理引擎控制者
- expandAmplitude view展开时抖动动作的振幅
- keyboardUtil 自动处理键盘遮挡事件工具对象ZYKeyboardUtil

Delegate func:
- optional func zyTableViewDidSelectRow(tableView: UITableView, indexPath: NSIndexPath)

对外会用到的func:
- dismissPreview()
让thumbnailView消失，在TopView,BottomView等没有zyThumbnailTableView对象的地方可以使用通知NOTIFY_NAME_DISMISS_PREVIEW
- reloadMainTableView()
重新加载tableView

Usage:

——结合Demo介绍使用方法：
创建ZYThumbnailTableViewController对象：

<code class="language-swift hljs fix has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-attribute" style="box-sizing: border-box;">zyThumbnailTableVC </span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;"> ZYThumbnailTableViewController()</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

配置tableViewCell必须的参数：cell高，cell的重用标志符，tableView的数据源等

<code class="language-swift hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">zyThumbnailTableVC<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tableViewCellReuseId</span> = <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"DIYTableViewCell"</span>
zyThumbnailTableVC<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tableViewCellHeight</span> = <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">100.0</span>
//当然cell高可以在任何时候动态配置
zyThumbnailTableVC<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tableViewDataList</span> = dataList
zyThumbnailTableVC<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.tableViewBackgroudColor</span> = UIColor<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.whiteColor</span>()
//背景颜色可不设置，默认为白色</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

接下来给ZYTableView配置你自己的tableViewCell，当然除了createCell外还可以在里面进行其他额外的操作，不过这个Block只会在需要生成cell的时候被调用，而重用cell并不会

<code class="language-swift hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//--------insert your diy tableview cell</span>
zyThumbnailTableVC.configureTableViewCellBlock = {<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">return</span> DIYTableViewCell.createCell()
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

配置cell的update方法，tableView配置每个cell必经之处，除了updateCell可以添加额外的操作。这里要注意updateCell的时候建议尽量使用zyThumbnailTableVC对象里的数据源datalist,同时要注意时刻保证VC对象里的数据源为最新，接口回调更改数据源时不要忘了对zyThumbnailTableVC.tableViewDataList的更新。

<code class="language-swift hljs markdown has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">zyThumbnailTableVC.updateTableViewCellBlock =  { [<span class="hljs-link_label" style="box-sizing: border-box;">weak self</span>](<span class="hljs-link_url" style="box-sizing: border-box;">cell: UITableViewCell, indexPath: NSIndexPath</span>) -> Void in
<span class="hljs-code" style="box-sizing: border-box;">    let myCell = cell as? DIYTableViewCell</span>
<span class="hljs-code" style="box-sizing: border-box;">    //Post是我的数据model</span>
<span class="hljs-code" style="box-sizing: border-box;">    guard let dataSource = self?.zyThumbnailTableVC.tableViewDataList[indexPath.row] as? Post else {</span>
<span class="hljs-code" style="box-sizing: border-box;">        print("ERROR: illegal tableview dataSource")</span>
<span class="hljs-code" style="box-sizing: border-box;">        return</span>
<span class="hljs-code" style="box-sizing: border-box;">    }</span>
<span class="hljs-code" style="box-sizing: border-box;">    myCell?.updateCell(dataSource)</span>
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li></ul>

配置你自己的顶部扩展视图 & 底部扩展视图（expansionView）
- 两个Block均提供indexPath参数，只是因为我的BottomView的业务暂时不需要识别对应的是哪个cell，所以使用时把参数省略掉了。
- 这里还有一个对zyThumbnailTableVC.keyboardAdaptiveView的赋值，是因为我的BottomView中包含有TextField，正如上文所说，ZYKeyboardUtil会自动帮我处理键盘遮挡事件。(==注意==：赋值给keyboardAdaptiveView的和我往Block里送的是同一个对象)

<code class="language-swift hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//--------insert your diy TopView</span>
zyThumbnailTableVC.createTopExpansionViewBlock = { [weak self](indexPath: NSIndexPath) -> UIView <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//Post是我的数据model</span><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">let</span> post = self?.zyThumbnailTableVC.tableViewDataList[indexPath.row] <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">as</span>! Post<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">let</span> topView = TopView.createView(indexPath, post: post)!topView.<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">delegate</span> = self;<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">return</span> topView
}<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">let</span> diyBottomView = BottomView.createView()!
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//--------let your inputView component not cover by keyboard automatically (animated) (ZYKeyboardUtil)</span>
zyThumbnailTableVC.keyboardAdaptiveView = diyBottomView.inputTextField;
<span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//--------insert your diy BottomView</span>
zyThumbnailTableVC.createBottomExpansionViewBlock = { _ <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">return</span> diyBottomView
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li><li style="box-sizing: border-box; padding: 0px 5px;">15</li><li style="box-sizing: border-box; padding: 0px 5px;">16</li></ul>

结合ZYKeyboardUtil工作的效果:

就这样，属于你自己的thumbnailtableView就完成了。展开，关闭，基本功能上都能使用，但是如果在topView，bottomView中有什么交互功能之类的，就要在自己的头部尾部扩展控件和自定义的tableViewCell里面完成了，ZYThumbnailTableView提供cell的indexPath贯通三者通讯交流。
回看下Demo中的交互是怎样利用indexPath的：

标记为已读后，小圆点会消失
标识为喜欢后，会在对应的cell旁边出现一个星星

createView的时候我将从createTopExpansionViewBlock参数中得到的indexPath储存在我的topView对象中，当favorite按钮被点击时就可以indexPath为凭据利用代理改变对应数据源里的对应状态，同时在下次createView时根据indexPath取得对应的数据源来显示。如果这些交互会更新一些与cell相关的数据，还可以在代理方法中调用zyThumbnailTableVC.reloadMainTableView()让tableView重新加载一遍。

还有对于导航条样式处理的话，Demo中直接在外面对zyThumbnailTableView对象的navigationItem做处理，亦或者可以在我的源代码中让ZYThumbnailTabelViewController继承你封装过导航栏样式的父类。
