What's special about a const @"SomeString"?

Question

Example:

FOUNDATION_EXPORT NSString * const NSLocalNotificationCenterType;

What is changed through that type qualifier? I understood it, if const was in front of the asterisk.

Answer 1

The const after the * means that the pointer itself is constant. That is, you can't do

NSString *myString = @"abcde";
NSLocalNotificationCenterType = myString;
