ios - 关闭呈现的 View Controller 后推送 View Controller

Question

我有这个导航堆栈

RootVC ---> VC1 -->(演示)-> ModalVC

我有VC2(不在导航堆栈中)。

在呈现 ModalVC 时，我想单击 ModalVC 中的按钮来关闭 ModalVC，然后在 VC1 之后将 VC2 插入导航堆栈一键点击。它应该看起来像这样:

RootVC ---> VC1 ---> VC2

我尝试了很多方法来实现它，但只有当我返回到我的RootVC时才触发事件。

我尝试与代表一起完成:

在ModalVC中点击:

[self dismissViewControllerAnimated:YES completion:^{
   if ([self.delegate respondsToSelector:@selector(dismissAndPush:)]) {
       [self.delegate performSelector:@selector(dismissAndPush:) withObject:VC2];
   }
}];

在VC1中:

- (void)dismissAndPush:(UIViewController *)vc {
    [self.navigationController pushViewController:vc animated:NO];

}

请帮助理解这种行为。我的错误在哪里？

来自Apple Documentation :

The presenting view controller is responsible for dismissing the view controller it presented.

所以，VC1 应该解雇 ModalVC，尝试这样做

点击时的 ModalVC:

   if ([self.delegate respondsToSelector:@selector(dismissAndPush:)]) {
       [self.delegate performSelector:@selector(dismissAndPush:) withObject:VC2];
   }

在 VC1 中:

- (void)dismissAndPush:(UIViewController *)vc {

[self dismissViewControllerAnimated:YES completion:^{
    [self.navigationController pushViewController:vc animated:NO];
}];

}
