title: how to open phone dialler in iOS 9?
body: <p>I found solution that I need to add some code in <code>info.plist</code>. I did it like below:</p>
  
  <pre><code>&lt;key&gt;LSApplicationQueriesSchemes&lt;/key&gt;
  &lt;array&gt;
      &lt;string&gt;tel&lt;/string&gt;
  &lt;/array&gt;
  </code></pre>
  
  <p>still no help.
   I get this error:</p>
  
  <blockquote>
    <p>"-canOpenURL: failed for URL: "tel://4806501708" - error: "This
    app is not allowed to query for scheme tel"</p>
  </blockquote>
  
  <p>my code for opening dialler:</p>
  
  <pre><code>NSString *phoneNumber = [@"tel://" stringByAppendingString:lblVenPhoneValue.text];
  if ([UIApplication.sharedApplication canOpenURL:[NSURL URLWithString:phoneNumber]]) {
          [UIApplication.sharedApplication openURL:[NSURL URLWithString:phoneNumber]];
  </code></pre>
  
  <p>What do I need to do?<br>
  Thanks in Advance</p>
