title: iOS: reload table and change map region on mother view controller from popover
body: <p>I have a ViewController with a TableView and a MapView and a button which opens a PopOver with another TableView. There the user can select some positions which should be shown on the Table and the MapView in the mother ViewController.</p>
  
  <p>I have a function which calculates the table data and draws those annotations in the mother ViewCoontroller. This is called from the child ViewController by initiating it:</p>
  
  <pre><code>MotherViewController * MVC = [[MotherViewController alloc] init];
  [MVC calculateresults];
  </code></pre>
  
  <p>The selected data is then passed back via protocol and the function calculates the proper results. However the table won't reload because [self.TableView reloaddata] doesnt work when the PopOver is still opened. If I close the PopOver and start the function directly on the mother ViewController everything works fine.</p>
  
  <p>Tried already this, but doesn't work:

  <p>How can i update a Map and a Table in a mother ViewController while a PopOver is opened?</p>
