关闭视图时分页视图层次结构被破坏

Question

我将 SLPagingView (https://github.com/StefanLage/SLPagingView/) 开源库用于基于分页视图的应用程序，例如 Twitter 或 Tinder。从某个页面我打开一个详细视图。当我回来时，分页视图的布局被破坏了。

DetailViewController.m

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

事实上，我注意到应用的层次结构就在 DetailView 出现之前被破坏了。

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];*/
}

我收到了 Presenting view controllers on detached view controllers is discouraged 警告。我尝试用 self.navigationController 或 self.parentViewController.navigationController 替换 self 但两者都不起作用。

是否有人使用此库解决了这个问题或知道解决方案？

已修复。我修改了 SLPagingView 库。在initWithNavBarControllers:、initWithNavBarItem:等生命周期方法中添加[self addChildViewController:ctr]。检查差异：https://www.diffchecker.com/cnlvslym
