目标：使视图控制器具有多个
页面并且可以通过分段控制器进行交换,
页面内容可以垂直滚动
细节：
>我制作了一个pagviewcontroller并将其作为子视图嵌入到主视图控制器中
@H_
502_6@//add pageviewcontroller as subview to viewcontroller
if let vc = storyboard?.instantiateViewControllerWithIdentifier("ProfileEditController"){
self.addChildViewController(vc)
self.view.addSubview(vc.view)
EditTabs = vc as! UIPageViewController
EditTabs.dataSource = self
EditTabs.delegate = self
//define F
irst page
EditTabs.setViewControllers([pagesAtIndexPath(0)!],direction:.Forward,animated: true,completion: nil)
EditTabs.didMov
etoParentViewController(self)
//bring segmented view buttons to front of pageViews
self.view.bringSubviewToFront(self.topTabs)
}

如何解决这个问题？
您的指导将非常感谢
谢谢,
>我创建了
一个带有PageViewController的视图控制器,其中包含三个具有滚动视图的视图控制器.它工作正常.
