ios - uipageViewController 没有加载 y=0 的 View

Question

我正在使用 pagevew Controller 来实现抽屉功能。一切正常，但第一次加载 View 时，它会留下状态栏的空间并在状态栏下开始。我需要从 y= 0 显示 View

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)
            
}

我试过

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，我正在使用这个库 drawer

它是这样显示的并希望像这样显示

一件事是，如果我触摸屏幕上的任何地方，它就会恢复正常

Answer 1

只需选择放置 pageviewcontroller 的 Storyboard，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。或者你可能只是对 toplayout 设置了约束，所以将它设置为从 toplayout 到 view
