What is a better practice when defining a const NSString object in objective-c?

Question

When i read colleagues\' code in my team, i usually found there were two different types of definition for const NSString objects:

static NSString const *

Answer 1

I prefer static const NSString *var; because staticand const are qualifiers for the NSString pointer. Only the pointer is const not the NSString.

The NSString will be constant because it is not mutable but a const NSMutableString *s will not make s mutable String become constant and so not modifiable. The pointer to the mutable String s will be constant and the compiler won't allow you to modify it.

Sorry for the inversion: Ken Thomases is right: int * const Var; means the pointer is constant and cannot be changed, but the data it points to can be changed. const int * Var means the data pointed to by Var cannot be changed.
