如何在UIPageViewController中使用popover控制器？

Question

我可以使用弹出框控制器返回页面视图控制器中的先前视图控制器。有没有办法这样做。

我正在尝试此代码。

-(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;

 }
