title: Startup image - splashscreen
body: <p>Here is my app code </p>
  
  <pre><code>Ext.application({
  
      {...}
  
      isIconPrecomposed: false,
      name: 'CarboZero',
      startupImage: {
          '320x460': 'resources/startup/splashscreen.png',
          '640x920': 'resources/startup/splashscreen.png',
          '640x1096': 'resources/startup/splashscreen.png',
          '768x1004': 'resources/startup/splashscreen.png',
          '748x1024': 'resources/startup/splashscreen.png',
          '1536x2008': 'resources/startup/splashscreen.png',
          '1496x2048': 'resources/startup/splashscreen.png'
      },
  
      launch: function() {
  
          Ext.create('CarboZero.view.InitView', {fullscreen: true});
      }
  
  });
  </code></pre>
  
  <p>When it lauches in IOS simulator, it still shows the sencha logo startup image... why? Do I need to do something more to get it working?</p>
