Swift3 UIPAGE控制指示点
我有一个页面控制器，指示点消失了！我想在最后一页就把它们消失！ 我还有另一个问题 我想从底部移动这些点+100！ 我的最后一个问题是：哪种方法可以帮助我在页面视图控制器的任何页面中编写任何方法？（我想在用户看到所有页面时控制这些页面） 这是我的密码Swift3 UIPAGE控制指示点,swift3,uipageviewcontroller,Swift3,Uipageviewcontroller,我有一个页面控制器，指示点消失了！我想在最后一页就把它们消失！ 我还有另一个问题 我想从底部移动这些点+100！ 我的最后一个问题是：哪种方法可以帮助我在页面视图控制器的任何页面中编写任何方法？（我想在用户看到所有页面时控制这些页面） 这是我的密码 class pageVC : UIPageViewController , UIPageViewControllerDataSource , UIPageViewControllerDelegate { let pageVC = UIPageC
