[SOLVED] Paging view hierarchy broken when dismissing a view

Paging view hierarchy broken when dismissing a view

I use the SLPagingView (https://github.com/StefanLage/SLPagingView/) open source library for a paging view based app like Twitter or Tinder. From some page I open a detail view. When I come back the layout of the paging views is broken.

DetailViewController.m

- (void)backButtonPressed {
    [self dismissViewControllerAnimated:YES completion:nil];
}

In fact I noticed that the hierarchy of the app is broken just before the DetailView appears.

SomePageViewController.m

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    // Perform segue to detailView
      [self performSegueWithIdentifier:@"actionDetail" sender:nil];

   /* Does not work with a modal view controller either
 UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main"bundle:nil];
    DetailViewController *detailViewController =
(DetailViewController *)
    [storyboard instantiateViewControllerWithIdentifier:@"detailcontroller_id"];
[self pushViewController:detailViewController animated:YES];*/
}

I got the Presenting view controllers on detached view controllers is discouragedwarning. I tried to replace self by self.navigationControlleror self.parentViewController.navigationControllerbut both don't work.

Does anyone using this library fix this issue or know a solution?

Solution

Fixed. I modified the SLPagingView library. Add [self addChildViewController:ctr] in initWithNavBarControllers:, initWithNavBarItem: and other life cycle methods. Check the differences: https://www.diffchecker.com/cnlvslym
