11 | ``` 12 | 即可。 13 | #### 方式二 14 | ``` 15 | pod 'CHD_ListView_Structure' 16 | ``` 17 | 然后导入头文件并调用上面的方法。 18 | ## 特征 19 | * 支持**UITableView**和**UICollectionView**结构查看 20 | * 支持只查看二者中一个，关闭另一个 21 | * 无侵入，无需继承，一句话开启关闭 22 | * 无论开启或关闭，只在**DEBUG**模式下生效 23 | * **Header**、**Cell**、**Footer**使用不同颜色线框包围，并在其上展示类名及其**Index** 24 | * 提供一个简单的可拖动的**Toggle**按钮，实时隐藏或显示**ListView**的结构 25 | * 简单的内存泄漏判断依据（点击**Toggle**按钮时会打印当前存活的**ListView**总个数，当你返回到上一页面再次点击**Toggle**按钮时，如果个数未减少，那么可能存在内存泄漏） 26 | ## 效果 27 | #### 1、百思不得姐(高仿) 28 | 对开源项目[百思不得姐(高仿)](https://github.com/targetcloud/baisibudejie)做了结构分析，其中部分效果图如下: 29 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/BSBDJ/IMG_1663.PNG?raw=true) 30 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/BSBDJ/IMG_1664.PNG?raw=true) 31 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/BSBDJ/IMG_1665.PNG?raw=true) 32 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/BSBDJ/IMG_1666.PNG?raw=true) 33 | 34 | #### 2、网易云阅读 35 | 借助神奇的工具[IPAPatch](https://github.com/Naituw/IPAPatch)来看下大厂是如何使用tableView的,部分页面如下: 36 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/WYYYD/IMG_1667.PNG?raw=true) 37 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/WYYYD/IMG_1668.PNG?raw=true) 38 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/WYYYD/IMG_1669.PNG?raw=true) 39 | ![](https://github.com/donggelaile/CHD_ListView_Structure/blob/master/ScreenShots/WYYYD/IMG_1670.PNG?raw=true) 40 | 41 | 42 | ## 其他 43 | 如有问题，还请指正，共同进步。如果对您有所帮助，希望给颗✨✨(即使现在不用，收藏起来也是极好的) 44 | ## LICENSE 45 | MIT 46 | -------------------------------------------------------------------------------- /ScreenShots/BSBDJ/IMG_1663.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/BSBDJ/IMG_1663.PNG -------------------------------------------------------------------------------- /ScreenShots/BSBDJ/IMG_1664.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/BSBDJ/IMG_1664.PNG -------------------------------------------------------------------------------- /ScreenShots/BSBDJ/IMG_1665.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/BSBDJ/IMG_1665.PNG -------------------------------------------------------------------------------- /ScreenShots/BSBDJ/IMG_1666.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/BSBDJ/IMG_1666.PNG -------------------------------------------------------------------------------- /ScreenShots/WYYYD/IMG_1667.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/WYYYD/IMG_1667.PNG -------------------------------------------------------------------------------- /ScreenShots/WYYYD/IMG_1668.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/WYYYD/IMG_1668.PNG -------------------------------------------------------------------------------- /ScreenShots/WYYYD/IMG_1669.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/WYYYD/IMG_1669.PNG -------------------------------------------------------------------------------- /ScreenShots/WYYYD/IMG_1670.PNG: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/donggelaile/CHD_ListView_Structure/928d5adc746b318e6ab0f9e988cd1cad352467fe/ScreenShots/WYYYD/IMG_1670.PNG --------------------------------------------------------------------------------
