iOS: How to save, get access token from foursquare

Question

How can I get the access token from a foursquare request in cocoa? I am accessing this authentication to get the token from foursquare:

https://foursquare.com/oauth2/authenticate?client_id=XXXXXXXXXXXXXX&response_type=token

is this valid?

I had also tried this: https://foursquare.com/oauth2/access_token?client_id=XXXXXXXXXXXXXX&client_secret=XXXXXXXXXXXXXX&grant_type=authorization_code&redirect_uri=http%3A%2F%2Flocalhost%2F&code=CODE

but returns this JSON response: {"error":"redirect_uri_mismatch"}

and how can I save and get the token from here? any suggestion guys?
