UIPageViewController 有奇怪的大小 [英] UIPageViewController has strange size

问题描述

我在我的应用中使用了 UIPageViewController.它工作得很好，但是当我翻页时，下一页似乎在比屏幕大的框架中初始化: 翻页时，只有下一个 viewController 的视图的一部分适合屏幕.

I am using a UIPageViewController in my app. It works quite well, but when I turn pages, the next page seems to get initialized in a frame that is bigger than the screen: While turning the page, only a part of the view of the next viewController fits on the screen.

我正在viewDidLoad 中初始化UIPageViewController 并开始记录PageVC 的帧、它的子视图和parentVC.每一帧似乎都没问题，只有我登录 viewControllerAfterViewController 的 UIPageViewController' 的帧的宽度几乎是屏幕实际大小的两倍.

I am initializing the UIPageViewController in viewDidLoad and started to log the frames of the PageVC, its subviews and the parentVC. Every frame seems to be okay, only the UIPageViewController's frame, which I log in viewControllerAfterViewController has a width that is nearly the double of the screen's actual size.

推荐答案

我终于通过在初始化 PageVC 时将正确的框架设置为 UIPageViewController 的视图解决了这个问题:

I finally solved this issue by setting the right frame to the UIPageViewController's view when initializing the PageVC:

pageViewController.view.frame = self.view.frame;

其中 pageViewController 是我初始化的 UIPageViewController，self 是 pageVC 的父 VC.

Where pageViewController is the UIPageViewController I initialize, and self is the parent VC of the pageVC.

希望这对有类似问题的人有所帮助.

Hope this helps anyone with similar problems.
