iOS如何实现网络搜索和关键字高亮

Answer 1

自己在返回的数据中搜索子串 [data rangeOfString:@"xxx"];

然后用 NSAttributedString 高亮所需范围:

NSString *data;
NSRange range = [data rangeOfString:@"your keyword"];
NSMutableAttributedString *attr;
[attr setAttributes:@{NSForegroundColorAttributeName: yourColor
              range:range];
