iOS Swipe Tableviewcell(左右滑动出现按钮)

1.背景                                                                      

     看到QQ的左右滑动Tableviewcell时可以出现多个菜单，觉得很高大上，因为没这种需求，

也只是需要一个删除按钮，这个系统已经帮我们实现了，只需要实现几个代理就可以，做出左划

出现删除按钮，这个我就不再这里说了，Google上你应该很容易实现，这里要讲的是如何实现

多个按钮的左右滑动的实现。可以获取点击的是哪个按钮。

2.效果图

    

左右侧可以分开设置，即可以同时为图片，也可以一边图片一边文字。

3.实现原理                                                                      

  在cell里面按钮和手势，根据手势来控制视图的移动和显示。

4.自定义cell的核心代码
