Publishing an action without using backend server - ios

Question

I am using this code for my facebook request, which posts an image as well as text to the user's feed:
My question is, how can I add a parameter for location? I followed this tutorial: https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/show-nearby-places/
But I am unable to use a backend server. In the case that I don't want to use a backend server, how can I modify my code to publish a story, including the location (preferably linking to the facebook location) without using a backend server? I have the user selecting the place, and that works flawlessly. Currently I am interested in getting the "at Patxi's Chicago Pizza" to appear without using a backend server. Is this possible?
