推荐答案

文章视图以模态呈现，因此没有后退按钮.如果您更改故事板，以便通过推送转场呈现文章视图，您将获得一个后退按钮.如果你想保持模态展示，你可以在文章视图中添加一个 UIBarButton 项(即添加一个 UIToolbar 或将文章视图控制器嵌入到 UINavigationController 中，以便你可以更新导航工具栏的 UIBarButtonItems).

The article view is being presented modally, so there is no back button. If you change your storyboard so that you're presenting the article view with a push segue, you'll get a back button. If you want to maintain the modal presentation, you can add a UIBarButton item to the article view (ie, add a UIToolbar or embed the article view controller in a UINavigationController so that you can update the UIBarButtonItems of the navigation toolbar).
