title: Update UIButton title from other view...?
body: <p>I am developing an iPad app. At some stage I need to use dropdown type functionality. So, I'm using UIPopoverView for the same.</p>
  
  <p>When IBAction fire on tap of particular UIButton, I adjust popoverview rendering UITableViewController.</p>
  
  <p>And all thing working fine. I need when user tap any of the cell, related cell value need to set in attached UIButton title.</p>
  
  <p><img src="https://i.stack.imgur.com/L9RIi.png" alt="enter image description here"></p>
  
  <p>Here, popover view is the UITableViewController view, which I create separately. And call it on select Outlet IBAction.</p>
  
  <pre><code>CGRect dropdownPosition = CGRectMake(self.btnOutlet.frame.origin.x, self.btnOutlet.frame.origin.y, self.btnOutlet.frame.size.width, self.btnOutlet.frame.size.height);
  [pcDropdown presentPopoverFromRect:dropdownPosition inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
  </code></pre>
  
  <p>Thanks</p>
