Objective-C - Expression is not an integer constant expression

I got this error message when trying to do switch.

/Users/xxxxx/Documents/iOS/xxxxx/main.m:83:14: Expression is not an integer constant expression

My code

char *anotherCharacter = "a";
        switch (*anotherCharacter) {
        case "a":
                NSLog(@"The letter a");
        case "A":
                NSLog(@"The letter A");
        default:
                NSLog(@"Not the letter A");
        }

Change "a" to 'a' and "A" to 'A' respectively. 'a' is an integer type actually while "a" is a string
