if the string is mutable  then you can transform it in place using this form    string replaceOccurrencesOfString                              withString                                options 0                              range NSMakeRange 0  string length      this is also useful if you would like the result to be a mutable instance of an input string   NSMutableString   string    concreteString mutableCopy    string replaceOccurrencesOfString                              withString                                options 0                              range NSMakeRange 0  string length
