The final word on NSStrings: Mutable and Immutable

Question

I\'ve read in several books... and online... about immutable and mutable strings. They claim \"immutable strings\" can\'t be changed. (But they never define \"change\".)

Answer 1

By default, NSString used in objective C language is immutable. NSMutableString is used to declare & define a mutable string. Nothing in an immutable string can be changed. Not the length, not the characters, nothing.
