BINTableViewHandle

让控制器远离代理

最大的好处:之前项目三百多个类,采用一个控制器绑定一个cell类,感觉太繁琐和低效,所以有了此类的产生.

所有的代理方法都走这2个类,如果需要特殊定制的部分,从外部传入即可.tableView属于控制器,但是代理属于着2个类,cell也可外部传入,cell作为高复用组件各种cell自由组合.

(从此不用再繁琐配置UITableView视图了,适用范围:所有列表)

#import "BINTableViewHandle.h"

用于单sections列表数据展示(一个cell一个数据模型)

#import "BINTableViewHandleSections.h"

用于多sections列表数据展示(一个section一个数据模型)

备注:此处默认cell是固定高度,如需要实时计算,请自己缓存(思路:建议高度字典,indexPath的section和row为key,计算的高度为值,字典没有则计算并存到字典,有直接返回).
