在刷过最后一个视图控制器后,如何解除/弹出UIPageViewController？
基本上想要用图像制作一个教程样式的分页视图,并在用户从最后一页滑到“下一页”后解散.
基本上想要用图像制作一个教程样式的分页视图,并在用户从最后一页滑到“下一页”后解散.
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {
NSUInteger index = [(EmailTutorialViewController *)viewController index];
index++;
if (index == 5) {
[self.navigationController popViewControllerAnimated:YES]; // this doesn't do anything
return nil;
}
return [self viewControllerAtIndex:index];
}
解决方法
这是我用过的简单解决方案：
在
– (UIViewController *)pageViewController：(UIPageViewController *)pageViewController viewControllerAfterViewController：(UIViewController *)viewController;
为索引返回空控制器== 5并添加此UIPageViewControllerDelegate方法：
- (void)pageViewController:(UIPageViewController *)pageViewController
willTransitionToViewControllers:(NSArray *)pendingViewControllers
{
EmailTutorialViewController *viewController =
[pendingViewControllers objectAtIndex:0];
if ([viewController index] == 5)
{
[self.navigationController popViewControllerAnimated:YES];
}
}
