IIRC they're optimized to point to the same memory location (I
wasn't sure, so I tested and confirmed).
I usually do:
NSString * const kConstantNameHere = @"foo";
That's what I've seen in Apple headers (with an extern at the
beginning and no assignment in said headers, of course).
Except that the reason for *that* is to have the names of the strings
in the public API but to keep the content of the strings out of it,
which is presumably not a consideration for the OP.
I'd choose the #define version, and give the compiler elbow room to do
its job of optimizing away duplicate literals -- and whatever else it
can do, such as possibly putting string literals in read-only address
space.
But the difference (if any) between the two approaches is so minimal
that personal preference is a fine criterion for deciding. :)
