Is it necessary to assign a string to a variable before comparing it to another?

Question

I want to compare the value of an NSString to the string \"Wrong\". Here is my code:

NSString *wrongTxt = [[NSString alloc] initWithFormat:@\"W         


        

Answer 1

Brian, also worth throwing in here - the others are of course correct that you don't need to declare a string variable. However, next time you want to declare a string you don't need to do the following:

NSString *myString = [[NSString alloc] initWithFormat:@"SomeText"];

Although the above does work, it provides a retained NSString variable which you will then need to explicitly release after you've finished using it.

Next time you want a string variable you can use the "@" symbol in a much more convenient way:

NSString *myString = @"SomeText";

This will be autoreleased when you've finished with it so you'll avoid memory leaks too...

Hope that helps!
