title: Dismiss the popover view
body: <p>I have a root view controller in which I load a sub view that contains three buttons. When I touch one of them a popover is shown. The popover contains an image view and a bar with a Done button. I want to dismiss this popover when the Done button is touched. To accomplish this I am using this code</p>
  
  <pre><code>- (IBAction)btnDone:(UIBarButtonItem *)sender {
      [self.view removeFromSuperview];
  
          [APPDELEGATE.parkDetail. popoverController dismissPopoverAnimated:YES];
     // [APPDELEGATE.parkDetail.popoverController dismissPopoverAnimated:YES ];
  
  
  }
  </code></pre>
  
  <p>and the popover is presented like this</p>
  
  <pre><code>- (IBAction)btnParkMap:(id)sender {
         [popoverController dismissPopoverAnimated:YES];
      if ([popoverController isPopoverVisible]) {
          [popoverController dismissPopoverAnimated:YES];
      } else {
          parkMap * v = [[parkMap alloc]initWithNibName:@"parkMap" bundle:nil];
          v.contentSizeForViewInPopover = CGSizeMake(350, 300);
          popoverController = [[UIPopoverController alloc] initWithContentViewController:v];
                 CGRect popRect = CGRectMake(self.btnShowPopover.frame.origin.x+330,
                                      self.btnShowPopover.frame.origin.y+170,
                                      self.btnShowPopover.frame.size.width,
                                      self.btnShowPopover.frame.size.height);
  
  
          [popoverController presentPopoverFromRect:popRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
            }
  }
  </code></pre>
