ios - 包含他的 View 下的 UIContainerView 元素

Question

UIContainerView 有点问题。我的 containerView 中的每个元素都在我的 UIPageController

生成的 ViewController 下

这张图片会更明确:

所以在这里，我的蓝色按钮将位于 UIImageView(机器人的 viewController)下，我需要它在上面。我不明白为什么，如果有人有我的想法。

结果:

我如何创建我的 PageVieWController :

 fileprivate func createPageViewController() {
    let pageController = self.storyboard!.instantiateViewController(withIdentifier: "PageController") as! UIPageViewController
    pageController.dataSource = self

    if contentImages.count > 0 {
        let firstController = getItemController(0)!
        let startingViewControllers = [firstController]
        pageController.setViewControllers(startingViewControllers, direction: UIPageViewControllerNavigationDirection.forward, animated: false, completion: nil)
    }

    pageViewController = pageController
    addChildViewController(pageViewController!)
    self.view.addSubview(pageViewController!.view)
    pageViewController!.didMove(toParentViewController: self)
}

以及我如何实例化我的 pageItem :

fileprivate func getItemController(_ itemIndex: Int) -> ABTutorialPageItemViewController? {
    if itemIndex < contentImages.count {
        let pageItemController = self.storyboard!.instantiateViewController(withIdentifier: "ItemController") as! ABTutorialPageItemViewController
        pageItemController.itemIndex = itemIndex
        pageItemController.imageName = contentImages[itemIndex]
        return pageItemController
    }
    return nil
}

If you want to manipulate, show directly in action you can use this project : https://github.com/YanisSOTO/Simple-UIPageViewController-Example

通过替换解决:

self.view.addSubview(pageViewController!.view)

到:

 self.containerView.addSubview(pageViewController!.view)
