Question

我在核心数据中拥有一个数额的 " HUGE " 文本,并在我的表格View中使用了搜索栏(其中显示文本),并在有 " 财务主管和国家预报 " 的各实体中进行了搜索。

因此,UITableView 显示包含搜索词的“强度”文本结果 search united OR 2-3 字句的句子。

例如,如果我有一个类似“我对飞行型号飞机有广泛了解,并热爱核心数据”和搜索“飞行”,我只想显示“......对“强飞”型号飞机有广泛的了解..................关于“强飞”型号飞机的知识......”。

我该怎么做?

Answer 1

你要用粗体显示吗?

如果回答否,答案如下:

first get the range of the text that has been searched, for example let say you were searching for "word" in sentence "this is the word am searching" search for the range of "word" that is 12, and save it in a variable then get the a substring with the range from 12 - 10 (range [2,10]) and save it in another variable lastly get a sbustring of 10 characters after the word for range [12+4,10] and save it into another variable

现在将所有这些变量(在+ " " " " " + " 字 " + " + " + " 后)合并并显示

如果您需要用黑体字来表示, 那么您就可以使用一些图书馆, 如“ OHATFlativeLabel ”, 读更多 < a href=> https://github.com/ AliSoftware/ OHATFliveLabel / rel = “ nofollow” > https://gitub. com/ AliSoftware/ OHATFiveLabel
