导航控制器中的PageViewController ios中滚动问题的子视图控制器 导航控制器-父级 页面视图控制器-导航控制器的子级 DetailsViewController-要在PageViewController中显示的ViewController

My DetailsViewController包含scrollview，具有不同数据的DetailsViewController数组被传递到pageviewcontroller

问题在于，只有pageviewcontroller的第一个viewController显示在navigartionbar下，其scrollview正在工作

但其余部分被推到导航控制器下，scrollview不工作

第一幅图：第一个详细信息视图控制器工作正常

第二幅图：当我刷卡时，数据集中的下一个细节查看控制器。在这里，内容被推到导航栏下，而scrollview不起作用

在做了进一步的研究之后，我发现除第一个之外，detailsviewcontroller的其余部分的navigationcontroller属性为nil

在父视图控制器中使用self.edgesForExtendedLayout=.None。它工作正常

这在我身上发生过一次，所以当时我添加了一个普通的视图控制器，并使其成为NavigationViewController的根控制器。现在，我在这个ViewController中添加了PageViewController。然后一切都很顺利。简而言之，尽管将NavigationController作为父控件

 self.edgesForExtendedLayout = .None
self.automaticallyAdjustsScrollViewInsets = false;
