目标C：如何实现“自动完成”功能（如谷歌搜索） [英] Objective C: How to implement 'auto complete' feature (like google search)

问题描述

我想实现一个具有自动完成功能（如谷歌搜索）搜索，如下面的截图中看到：

I want to implement a search with a auto-complete feature (like google search) as seen in the screenshot below:

例如，如果我的汽车钥匙，启动或含自动将显示在表格中结果列表

For example if I key auto, a list of results starting or containing auto will be displayed in the table

是否有任何教程或可用资源供我参考？

Are there any tutorials or resources available for my reference?

推荐答案

如果你只有一组内部要用于自动完成字符串的，即你是不是想从互联网动态抓取。然后，我创建了我都忍了在GitHub上一个类，西港岛线把每个用字符串开头，例如，@猫将返回字符串{@猫，@目录，@类别}。

If you have just an internal set of string you want autocompletion for, i.e. you are not trying to dynamically fetch them from the internet. Then I have created a class which I have put up on GitHub that wil turn every string that begins with a string, for example, @"cat" would return {@"cat", @"catalog", @"category"}.
