title: Instagram iPhone hook url scheme changed
body: <p>It seems that the update of Instagram Client on Oct.28th made a slight change to the hook url scheme on iOS development.</p>
  
  <p>I found it that the previous "<strong>instagram://camera</strong>" url scheme act unexpected link us to the camera page in Instagram App, not the photo library before.</p>
  
  <p>I also found that the <strong>Boomerang</strong> App that Instagram owned itself hook the photo library correctly, but I didn't find the relative hook on the api page.So I think there might exist a <strong>private hook</strong> scheme.</p>
  
  <p>Is there any way I can hook through Instagram App to photo library directly like before?</p>
