global C String const property in Objective-C

Question

Is anyway to get a global C String const property in Objective-C?

I'm doing something like this:

const char *content_type = [@"application/vnd.ccm.pmsg.v1+json" UTF8String];

@implementation StringChannelCallable

...

@end

And I get this error:

Initializer element is not a compile-time constant

If I declare the content_type inside a method, this works, but I need to have it for global purpose to don't duplicate code

you can't use method in the variable or constant‘s declare

and you should use c language grammar to declare const char *, like this :

const char *content_type = "application/vnd.ccm.pmsg.v1+json";

Both the pointer and the characters it points to should be const, like so: const char *const content_type = "application/vnd.ccm.pmsg.v1+json";.
