Can Objective-C switch on NSString?

Question

Is there a more intelligent way to rewrite this?

if ([cardName isEqualToString:@\"Six\"]) {
    [self setValue:6];
} else if ([cardName isEqualToString:@\"Se

BY FAR.. my FAVORITE "ObjC Add-On" is ObjectMatcher

objswitch(someObject)
    objcase(@"one") { // Nesting works.
        objswitch(@"b")
            objcase(@"a") printf("one/a");
            objcase(@"b") printf("one/b");
            endswitch // Any code can go here, including break/continue/return.
    }
    objcase(@"two") printf("It's TWO.");  // Can omit braces.
    objcase(@"three",     // Can have multiple values in one case.
        nil,              // nil can be a "case" value.
        [self self],      // "Case" values don't have to be constants.
        @"tres", @"trois") { printf("It's a THREE."); }
    defaultcase printf("None of the above."); // Optional default must be at end.
endswitch

AND it works with non-strings, TOO... in loops, even!

for (id ifNumericWhatIsIt in @[@99, @0, @"shnitzel"])
    objswitch(ifNumericWhatIsIt)
        objkind(NSNumber)  printf("It's a NUMBER.... "); 
        objswitch([ifNumericWhatIsIt stringValue])
            objcase(@"3")   printf("It's THREE.\n"); 
            objcase(@"99")  printf("It's NINETY-NINE.\n"); 
            defaultcase     printf("some other Number.\n");
       endswitch
    defaultcase printf("It's something else entirely.\n");
endswitch

It's a NUMBER.... It's NINETY-NINE.
It's a NUMBER.... some other Number.
It's something else entirely.

Best of all, there are SO few {...}'s, :'s, and ()'s
