    copied!<p>I'm trying out Rubymotion and can't seem to do figure how to accomplish what seems like a simple task.</p> <p>I've set up a UITableView for a directory of people. I've created a rails back end that returns json.</p> <p>Person model has a get_people class method defined:</p> <pre><code>def self.get_people BubbleWrap::HTTP.get("http://myapp.com/api.json") do |response| @people = BW::JSON.parse(response.body.to_str) # p @people prints [{"id"=&gt;10, "name"=&gt;"Sam"}, {etc}] to the console end end </code></pre> <p>In the directory_controller I just want to set an instance variable for @data to the array that my endpoint returns such that I can populate the table view.</p> <p>I am trying to do <code>@data = Person.get_people</code> in viewDidLoad, but am getting an error message that indicates the BW response object is being passed instead: <code>undefined method</code>count' for #BubbleWrap::HTTP::Query:0x8d04650 ...> (NoMethodError)` </p> <p>So if I hard code my array into the get_people method after the BW response block everything works fine. But I find that I am also unable to persist an instance variable through the close of the BW respond block.</p> <pre><code>def self.get_people BubbleWrap::HTTP.get("http://myapp.com/api.json") do |response| @people = BW::JSON.parse(response.body.to_str) end p @people #prints nil to the console # hard coding [{"id"=&gt;10, "name"=&gt;"Sam"}, {etc}] here puts my data in the table view correctly end </code></pre> <p>What am I missing here? How do I get this data out of bubblewrap's response object and in to a usable form to pass to my controllers?</p>
