I have checked the language hint list and could not find one for objective-c. My question is how should I give an objective-c hint?

Officially, it would be lang-m (it's based on the file extension), but the prettifier then uses the same handler as used for C and C++:
registerLangHandler(sourceDecorator({
'keywords': CPP_KEYWORDS,
'hashComments': true,
'cStyleComments': true,
'types': C_TYPES
}), ['c', 'cc', 'cpp', 'cxx', 'cyc', 'm']);
so you may as well use lang-c, which is what the default is for the objective-c tag.
Just use lang-c, that's what the questions tagged objective-c are getting.
