Objective C: convert a NSMutableString in NSString

Question

I have an NSMutableString, how can I convert it to an NSString?

Answer 1

NSMutableString is a subclass of NSString, so you could just typecast it:

NSString *string = (NSString *)mutableString;

In this case, string would be an alias of mutalbeString, but the compiler would complain if you tried to call any mutable methods on it.

Also, you could create a new NSString with the class method:

NSString *string = [NSString stringWithString:mutableString];
