在容器视图中的视图控制器中，如何访问包含容器的视图控制器？ [英] From within a view controller in a container view, how do you access the view controller containing the container?

问题描述

这很难说，但我有一个包含容器视图的视图控制器（vc1）（我正在使用故事板）。在该容器视图中是导航控制器和根视图控制器（vc2）。

This is tricky to word but I have a view controller (vc1) that contains a container view (I'm using storyboards). Within that container view is a navigation controller and a root view controller (vc2).

从vc2中我如何才能访问vc1？

From within the vc2 how can I get access to vc1?

或者，如何将vc1传递给vc2？ （请记住，我正在使用故事板）。

Or, how do I pass vc1 to vc2? (baring in mind that I'm using storyboards).

推荐答案

您可以使用 prepareForSegue 方法作为嵌入segue发生。你可以将self作为obj传递或存储对孩子的引用供以后使用。

You can use the prepareForSeguemethod in Vc1 as an embed segue occurs when the ContainerViewController is made a child. you can pass self as an obj or store a reference to the child for later use.

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    NSString * segueName = segue.identifier;
    if ([segueName isEqualToString: @"embedseg"]) {
        UINavigationController * navViewController = (UINavigationController *) [segue destinationViewController];
        Vc2 *detail=[navViewController viewControllers][0];
        Vc2.parentController=self;
    }
}
