title: Save JSon data in NSArray
body: <p>I'm trying to save some specific JSon data and store them in a simple NSArray.</p>
  
  <p>This is the JSon I have:</p>
  
  <pre><code>products = {
      72 =     {
          value_a = "something1";
          value_b = "something2";
          value_c = "something3";
      };
  
      73 =     {
          value_a = "something1";
          value_b = "something2";
          value_c = "something3";
      };
  
      74 =     {
          value_a = "something1";
          value_b = "something2";
          value_c = "something3";
      };
      [etc]
  }
  </code></pre>
  
  <p>This is how I assign the JSon data in a NSMutableArray.</p>
  
  <pre><code>NSMutableArray *array = [json objectForKey:@"products"];
  </code></pre>
  
  <p>What I need is to store, let's say, just value_b of each child in an array. Any suggestion?</p>
