本文介绍iOS中UITableView实现左滑删除及多选功能的方法，包括使用代理方法和自定义cell实现多选与全选，并展示了如何通过代码控制编辑状态。

刚好在公司做这一块的功能,现在来总结下,可能不是那么完善,以后慢慢再改进.

左滑删除
多选
一种混合的写法(同时有侧滑和多选并自定义多选的图片)

左滑删除

多选

tableView有个代理方法: 当返回UITableViewCellEditingStyleDelete的时候是可以左滑删除, 神奇的是当返回UITableViewCellEditingStyleDelete | UITableViewCellEditingStyleInsert的时候就变成了多选的样式.

<code class="hljs objectivec has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">#pragma mark 返回编辑样式</span>

这里写图片描述

另一种写法

公司要求是cell能够左滑删除,能多选,能全选.

1 利用xib来创建cell, 左边的小圆圈分为未选中和选中俩种状态(图片不同)
2 设置cell的属性 (titleLeftConstraint是titleLabel左边到小圆圈的约束)

<code class="hljs objectivec has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">@property</span> (<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">weak</span>, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">nonatomic</span>) <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">IBOutlet</span> <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">UIButton</span> *selBtn;

3 控制器里设置一些属性,并重写isEdit的set方法

4 一些方法
