You need a pointer to an instance of NSString. Example:

NSString *string1 = @"Hello!";
NSString **string2 = &string1; // get the address of string1
*string2 = @"changed"; // set what string2 points to be 'changed'

NSLog(@"string1:%@, string2:%@", string1, *string2); // should print "string1: changed, string2: changed"
