以编程方式删除 PageViewController

Question

我已按如下方式以编程方式添加 pageviewController。有用。但是，当我尝试使用 [self.pageViewController.view removeFromSuperview]; 删除时，它并没有删除它。

添加 pageViewController

self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
self.pageViewController.dataSource = self;
self.pageViewController.delegate = self;
PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = @[startingViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];

正在删除 pageViewController

[self.pageViewController.view removeFromSuperview];

使用下面的一组说明删除您的 pageViewController：

[self.pageViewController willMoveToParentViewController:nil];
[self.pageViewController.view removeFromSuperview];
[self.pageViewController removeFromParentViewController];
