Question

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

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

1. Convert your attributed string into an instance of NSMutableAttributedString.

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

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

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