title: Double tap outside action sheet popover presented using UIAlertController leads to going back to parent view in ios8 xcode 6 beta 5
body: <p>I have a action sheet which i am presenting using UIAlertcontroller in ios8 (xcode 6 beta 5).
  I am using UIAlertcontroller because UIActionsheet ( which is deprecated in iOS 8 ) was not working properly in ios8, on click of any option in the actionsheet leaded me back to the parent view. 
  Now I am facing one issue in UIAlertcontroller too, double tap outside the action sheet popover is leading me back to the previous parent view.
  Following is my code snippet:</p>
  
  <pre><code>UIAlertController *actionSheetIos8;
  
  actionSheetIos8 = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
  
  NSArray *buttonsArray = [self returnMoreArray];
  int startY = 10;
  for (int i = 0; i &lt; [buttonsArray count]; i++) {
  
      UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:[buttonsArray objectAtIndex:i] style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
          NSString *newStr = [buttonsArray objectAtIndex:i];
          newStr = [[newStr lowercaseString] stringByReplacingOccurrencesOfString:@" " withString:@"_"];
      }];
      [actionSheetIos8 addAction:defaultAction];        
  }
  UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:^(UIAlertAction *action) {
  }];
  
  [actionSheetIos8 setModalPresentationStyle:UIModalPresentationPopover];
  UIPopoverPresentationController *popPresenter = [actionSheetIos8
                                                   popoverPresentationController];
  popPresenter.sourceView = sender;
  popPresenter.sourceRect = [sender frame];
  dispatch_async(dispatch_get_main_queue(), ^ {
      [self presentViewController:actionSheetIos8 animated:YES completion:nil];
  });
  </code></pre>
