用另一个 NSAttributedString 替换 NSAttributedString 的子字符串 [英] Replace substring of NSAttributedString with another NSAttributedString

问题描述

我想用另一个 NSAttributedString 替换 NSAttributedString 的子字符串(例如 @"replace").

I want to replace a substring (e.g. @"replace") of an NSAttributedString with another NSAttributedString.

我正在寻找与 NSString 的 stringByReplacingOccurrencesOfString:withString: 用于 NSAttributedString.

I am looking for an equivalent method to NSString's stringByReplacingOccurrencesOfString:withString: for NSAttributedString.

推荐答案

1. 将您的属性字符串转换为 NSMutableAttributedString 的实例.

可变属性字符串具有 mutableString 属性.根据文档:

The mutable attributed string has a mutableString property. According to the documentation:

接收器跟踪对此字符串的更改并使其属性映射保持最新."

"The receiver tracks changes to this string and keeps its attribute mappings up to date."

因此您可以使用生成的可变字符串来执行与 replaceOccurrencesOfString:withString:options:range: 的替换.

So you can use the resulting mutable string to execute the replacement with replaceOccurrencesOfString:withString:options:range:.
