【背景】
需要用swift实现，联系人列表的那种页面：
就有点像：
手机自带的联系人列表或者微信联系人列表。
左边是根据字母分组的，tableview
右边有根据字母支持快速滑动定位的
【折腾过程】
1.搜：
swift contact list
swift draw contact list
参考：
Address Book Tutorial in Swift and iOS – Ray Wenderlich
Address Book Tutorial in iOS – Ray Wenderlich
Alterplay/APAddressBook · GitHub
好像是：
针对于每个人的详细联系信息的那种类：
不是我此处要的。
2.搜：
swift tableview contact list
参考：
Adding Section and Index List in UITableView | iOS Programming 101
这个是我要的，但是是ObjC的代码。
所以自己去参考自己折腾。
3.看了上面的内容，知道了：
针对A。。Z，每一个部分，都是叫section，分区，分组
而右边的a到z，则是index list，检索，索引列表
下载已有的，没添加分组和检索列表的示例代码：
相关的参考资料：
titleForHeaderInSection － UITableViewDataSource Protocol Reference
然后自己折腾。
【总结】
最后用代码：
用代码：
