objective c - Quicker if-statement: if `variable` is "value" or "value"

Question

How can you compare against multiple possibilities in one argument?

Example:

if ((integer == 2) || (integer == 5))

if ((string == "hello") || (string == "dolly))

Would save me a lot of code if you could write that like this:

if (integer == (2 || 5))

if (string == ("hello" || "dolly"))

Answer 1

First of all string comparasion doesn't work that way in C, I know nothing about objective-c, thought.

For the comparison against compile time integral constants, in C you have the switch statement:

switch (integer) {
case 2: ;
case 5: ;
   /* do stuff here */
}
