title: iOS 13.1 Objective-C ModalPresentation Fullscreen
body: <p>found next strange bug in iOS 13 presenting modally over fullscreen viewcontroller. Initially it was broken, it was opened in not a full screen so I tried next method described on
  <a href="https://stackoverflow.com/questions/56435510/presenting-modal-in-ios-13-fullscreen">this link</a>
  Now it loads and awaits touch to anywhere on the screen. 
  Currently this is Parent viewController, which should modally show TermsVC</p>
  
  <pre><code>mainView.hidden = YES;
          IDTermsViewController *termsVC = [[self storyboard] instantiateViewControllerWithIdentifier:@"IDTermsViewController"];
          termsVC.delegate = self;
          if (@available(iOS 13.0, *)) {
              [termsVC setModalPresentationStyle: UIModalPresentationFullScreen];
          }
          [self presentViewController:termsVC animated:YES completion:nil];
  </code></pre>
  
  <p>Currently after presenting this termsVC, i've got the next state like on the screenshot below. If i do any action - shake the phone, make screenshot, tap anywhere - TermsVC will appear!</p>
  
  <p>On previous ios version works fine.
