How to declare NSString constants for passing to NSNotificationCenter

Question

I\'ve got the following in my .h file:

#ifndef _BALANCE_NOTIFICATION
#define _BALANCE NOTIFICATION
const NSString *BalanceUpdateNotification
#endif
         


        

Answer 1

NSStrings are immutable, so declaring a const NSString * would be redundant; just use NSString *.

If what you're trying to do is declare that the pointer itself can't change, that would be:

   NSString * const BalanceUpdateNotification = @"BalanceUpdateNotification";
