uipageViewController没有加载y = 0的视图

Question

我正在使用pagevew控制器来实现抽屉的功能。每个工作正常，但第一次加载视图时，它会留下状态栏的空间并从状态栏开始。我需要显示y = 0

的视图

private func setupPageViewController() {
    pageViewController = UIPageViewController(transitionStyle: UIPageViewControllerTransitionStyle.Scroll, navigationOrientation: UIPageViewControllerNavigationOrientation.Horizontal, options: nil)
    pageViewController.dataSource = self
    pageViewController.delegate = self
    pageViewController.setViewControllers([stackPageVC[stackStartLocation]], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)
    var pageViewControllerY: CGFloat = 0
    var pageViewControllerH: CGFloat = 0
    if navigationBarShouldNotExist {
        pageViewControllerY = 0
        pageViewControllerH = Constants.ScreenHeight
    } else {
        pageViewControllerY = 0
        pageViewControllerH = Constants.ScreenHeightWithoutStatusBar
    }
    pageViewController.view.frame = CGRect(x: 0, y: pageViewControllerY, width: Constants.ScreenWidth, height: pageViewControllerH)


    pageViewController.view.backgroundColor = UIColor.clearColor()
    addChildViewController(pageViewController)
    view.addSubview(pageViewController.view)
    pageViewController.didMoveToParentViewController(self)

}

我尝试使用

for v: UIView in pageViewController.view.subviews {
        if (v is UIScrollView) {
            let scroll = v as! UIScrollView
            scroll.setContentOffset(CGPointMake(0, 0), animated: false)
            print("----")
        }
    }

对于抽屉功能我正在使用此库drawer

它显示为，并希望显示为

有一点是，如果我触摸屏幕上的任何地方，那么它会恢复正常

只需选择放置pageviewcontroller的故事板，在右侧有一个选项UnderTopBar只需取消选择该选项即可。你会得到解决方案。或者你可能只是设置了toplayout约束，所以设置从toplayout到视图
