cocoa编程第4版 8.6 挑战2 解答

概述该版本的RaiseMan不用Array Controller，全部手写代码。 要注意的有以下几点： 1.TableView每列的sort设置和AC版的相同，但要手写排序代理方法 2.TableView和add、remove按钮的绑定和一般cocoa程序相同 3.需要添加TableView每列的id 4.需要手写TableView的DataSource和Delegate的相关方法 5.Person类

该版本的RaiseMan不用Array Controller，全部手写代码。

要注意的有以下几点：
1.tableVIEw每列的sort设置和AC版的相同，但要手写排序代理方法
2.tableVIEw和add、remove按钮的绑定和一般cocoa程序相同
3.需要添加tableVIEw每列的ID
4.需要手写tableVIEw的DataSource和Delegate的相关方法
5.Person类和AppDelegate类方法和AC版的相同

代码如下：
