NSCharacterSet symbolCharacterSet example.
NSCharacterSet* symbols = [NSCharacterSet symbolCharacterSet];
if([symbols characterIsMember: yourCharacter]) {
//Check Your condition here
}
If you want to include many characters Use a combined NSCharacterset with NSMutableCharacterSet..
NSMutableCharacterSet *space = [NSMutableCharacterSet characterSetWithCharactersInString:@" "];
[space formUnionWithCharacterSet:[NSCharacterSet symbolCharacterSet]];
Use the space characterset to check the character
