Questions tagged [nsmutablestring]

The NSMutableString class declares the programmatic interface to an object that manages a mutable string — that is, a string whose contents can be edited — that conceptually represents an array of Unicode characters.

To construct and manage an immutable string — or a string that cannot be changed after it has been created — use an object of the NSString class.

The NSMutableString () class adds one primitive method 

-replaceCharactersInRange:withString:

to the basic string-handling behavior inherited from NSString . All other methods that modify a string work through this method.
