What key/values can I specify in withViewOptions parameter of usePageViewController method of PDFView of iOS11, PDFKit?

推荐答案

根据PDFKit中的文档，usePageViewController:withViewOptions:将给定的选项传递给位于查看器中的UIPageViewController.

According to the documentation found in PDFKit, usePageViewController:withViewOptions: passes the given options to the UIPageViewController located in the viewer.

viewOptions自变量被赋予UIPageViewController初始化程序，作为传递页面间距的一种方式，等等.

The viewOptions argument is given to the UIPageViewController initializer, as a way to pass in page spacing, etc.

UIPageViewController的可用选项为 UIPageViewControllerOptionSpineLocationKey 和 UIPageViewControllerOptionInterPageSpacingKey .

UIPageViewController's available options are UIPageViewControllerOptionSpineLocationKey and UIPageViewControllerOptionInterPageSpacingKey.
