title: set highlight of UISegmentedControl
body: <p>i´d like to set the highlighted segment without calling the assigned function.</p>
  
  <p>i call </p>
  
  <pre><code>segmentedControlLeft.selectedSegmentIndex = 1;
  </code></pre>
  
  <p>that works well for the segmentedControl but it generates UIControlEventValueChanged as well which calls my attached function and i´d like to avoid it calling again.</p>
  
  <p>is that possible?</p>
  
  <p>thank you! </p>
