Question

Can an NSString be reused like this:

NSString *string = @"first value";

NSLog(string);

string = @"second value";

NSLog(string);

This works when tested, but is it proper coding?

Thanks.

Answer 1

Yes, your example is totally fine. What is your concern about it being ‘improper’?

Edit: Strictly speaking it is probably safer to use:

NSLog(@"%@", string);

Instead of just logging the string directly. I don’t think that’s what you were asking, though.
