从 ParentViewController 中关闭 ChildView [英] Dismiss ChildView From ParentViewController

问题描述

我有一个父视图，可以像这样打开子视图:

I have a parent view that opens a child view like so:

ChildViewController *child = [[ChildViewController alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:child animated:YES];

哪个工作得很好.我需要从父视图中关闭子视图，但是当我这样做时，什么也没有发生.是不是因为当我打开子视图时父视图停止了它的所有进程?或者是我的代码: [child deniedModalViewControllerAnimated:YES]; ?谢谢

Which works perfectly fine. I need to dismiss the child view from the parent view but when I do that, nothing happens. Is it because the parent view stops all of its processes when I open the child view? Or is it my code: [child dismissModalViewControllerAnimated:YES]; ? Thanks

推荐答案

dismissModalViewControllerAnimated: 必须在调用 presentModalViewController:animated: 的同一对象上调用.

dismissModalViewControllerAnimated: has to be called on the same object that presentModalViewController:animated: was called on.

在你的例子中，它需要是 [self deniedModalViewControllerAnimated:YES];

In your example, it would need to be [self dismissModalViewControllerAnimated:YES];

如果您从以模态方式显示的控制器内部解除，就像@James Bedford 描述的那样[[self parentViewController]dismissModalViewControllerAnimated:YES];

If you were dismissing from inside the controller being displayed modally, it would be as @James Bedford described [[self parentViewController] dismissModalViewControllerAnimated:YES];
