title: iPhone 6 plus real device UIScreen mainScreen size strange
body: <p>When I use the <code>[UIScreen mainScreen]</code> to test for the Xcode 6 simulator, the size seems to be correct. </p>
  
  <p>With iPhone 6 size: <code>375 * 667</code> and iPhone 6 plus: <code>414 * 739</code>. </p>
  
  <p>But when I test <code>[UIScreen mainScreen]</code> in real iPhone 6 plus device, result shows that:</p>
  
  <pre><code>(lldb) po [UIScreen mainScreen]
  
  &lt;UIScreen: 0x12ce03f30; bounds = {{0, 0}, {375, 667}}; mode = &lt;UIScreenMode: 0x178039ae0; size = 1125.000000 x 2001.000000&gt;&gt;`
  </code></pre>
  
  <p>But when you test for scale, it will output <code>3.0</code> on real iPhone 6 plus device. So, is there any problem there?</p>
