JSON to NSDictionary literal <p>I need to build an <code>NSDictionary</code> that I can then parse with <code>NSJSONSerialization</code> in order to get a nice <code>JSON</code> formatted string.</p> <p>The final output of my JSON needs to be something like:</p> <pre><code>"Viewport":{ "BottomRight":{ "Latitude":1.26743233E+15, "Longitude":1.26743233E+15 }, "TopLeft":{ "Latitude":1.26743233E+15, "Longitude":1.26743233E+15 } } </code></pre> <p>I figured it might be easiest to use <code>NSDictionary</code> literals, but how would I create multi-level nested dictionaries doing it this way?</p> <p>Also, I will need to be setting the lat and long values when creating the dictionary.</p>
