title: This app is not allowed to query for scheme tel
body: <p>I just opened an old project onbjectif-c created in 2010, the application works correctly except an interface
  is not working.The error is -canOpenURL: failed for URL: "tel: 0" - error: "This app is not allowed to query for scheme tel".</p>
  
  <p>according to my research I find that the error is related to ios 9 but I do not find how to resolve it
  thank you</p>
