title: Why single backslash turns to double backslash
body: <p>The string <code>"\domain\path1\path2"</code> was turned to <code>"\\domain\\path1\\path2"</code> after using AFNetwork to get the JSON response. </p>
  
  <p>I got two comments "they are same",but the point is that when we use NSURL to create a remote url for EGOImageView to load, that will be different. The double <code>\\</code> will get failed. </p>
  
  <p>Why this happened ? </p>
