Question

I can create a regular NSString easily:

NSString *string = @"string value";    // Case 1

Is it possible to do something like this?

NSMutableString *mutableString = @"mutableString value";    // Case 2

Answer 1

You can initialize the string as mentioned in some of the other answers, but for constant strings like that, I prefer to send the -mutableCopy message:

NSString* string = @"string value";
NSMutableString* mutableString = [@"mutableString value" mutableCopy];

It just feels easy to read to me, but it’s a matter of style preference.
