如何在 UIPageViewController 中使用弹出框控制器？

Question

我可以使用弹出框控制器返回到页面视图控制器中的先前视图控制器吗？有什么办法可以吗？

我正在尝试这段代码。

-(void)goNext
{
Vcontr = [self.pageController.viewControllers objectAtIndex:0];

UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:pageController];

if(popoverController == nil){   //make sure popover isn't displayed more than once in the view
    popoverController = [[UIPopoverController alloc] initWithContentViewController:pageController];
}
[popoverController presentPopoverFromRect:self.view.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

popoverController.delegate = self;

 }
