Question

- (void)change:(int)a {
   int number = a;
   int max = 10;

   switch(max) {
     case number:
       //Do something
       break;

       //.... more cases
   }
}

This is just a small example of the issue I can’t seem to solve. I have looked at similar posts and answers usually include using constants via a #define or enum, however these are great when you have a constant that is fixed but if the value is passed through as a parameter how could I do this? if it’s possible at all. Any advice would be appreciated.

Answer 1

In a nutshell, case statements can only operate on constant expressions, so if you need more dynamic conditionals, you will have to use if statements.
