问题描述

基本上我想创建的内容可以从屏幕截图中得到最好的说明.

Basically what I want to create can be best illustrated from a screenshot.

我有一个人的列表视图，就像 FB Messenger 应用程序一样.我希望我的用户能够像屏幕截图中显示的那样拥有一个搜索栏.它应该具有以下属性:

I have a listview of people just like FB Messenger app. I want the ability for my users to have a search bar like the one shown in the screenshots. It should have the following properties:

1) 搜索栏应预览列表视图中所选人员的姓名

1) Search bar should preview names of people selected in the list view

2) 可以通过在预览搜索栏中的任何名称上按退格键来取消选择人员

2) People can be de-selected by hitting backspace on any name in the preview search bar

3) 搜索栏应该能够在用户输入时过滤底部的人员列表.

3) The search bar should be able to filter the bottom list of people as the user types.

我有属性 3) 的解决方案，但我对其他两个一无所知.请帮忙！！！
