【已解决】swift中如何实现联系人列表

Swift crifan 1395浏览 0评论

【背景】

需要用swift实现,联系人列表的那种页面:

android contact list example

 

ios app ui contact list

 

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:

IndexedTableDemoTemplate

IndexedTableDemo

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:
