13 | 14 | ####2、cell的注册 15 | 16 | > a. 使用`tableview`的`registerClass`方法来进行cell的注册 17 | > b. 若有多种类型的cell，则要用`registerClass`注册多个cell 18 | 19 |
20 | 21 | ####3、初始化cell，并返回cell高度 22 | 23 | > a. 在`heightForRowAtIndexPath`方法里，进行cell的初始化 24 | > b. 使用`systemLayoutSizeFittingSize`方法获取cell的高度 25 | 26 |
27 | 28 | ####4、cell赋值 29 | 30 | > 在`cellForRowAtIndexPath`方法里，进行cell的赋值 31 | 32 |
33 | 34 | ####5、使用`autolayout`对需要的控件进行布局 35 | 36 | > 有两种方式： 37 | > a. 使用xib 38 | > b. 重写自定义cell类里的`updateConstraints`方法，手动用代码进行布局 39 | 40 | 注：本文使用[Masonry](https://github.com/Masonry/Masonry)进行布局 41 | 42 |
43 | 44 | ####6、通知系统进行布局 45 | 46 | > 在自定义的cell类里的`layoutSubviews`方法，调用相关方法通知系统进行布局 47 | 48 |
49 | 50 | 51 | ##二、关键点 52 | 1、autolayout要设置正确，如果不正确，`systemLayoutSizeFittingSize`方法计算出来的高度是0 53 | 54 | ##三、示例代码 55 | 56 | > 假设有两种类型的cell，先自定义两个cell类 57 | > 分别命名为`AutoResizeCell` `SecondResizeCell` 58 | > `reuse identify`分别为`autoResizeCellId` `secondResizeCellId` 59 | 60 |
