关闭呈现的视图控制器后推送视图控制器 [英] push view controller after dismissing presented view controller

问题描述

我有这个导航栈

RootVC ---> VC1 --> (presenting)-> ModalVC

我有 VC2(不在导航堆栈中).

and I have VC2 (not in navigation stack).

在呈现ModalVC时，我想点击我的ModalVC中的按钮来关闭ModalVC，然后在VC1之后将VC2推入导航堆栈一键式.它应该是这样的:

When presenting ModalVC, I want to click on button in my ModalVC to dismiss ModalVC, then push VC2 into the navigation stack after VC1 at one click. It should look like this:

RootVC ---> VC1 ---> VC2

我尝试了很多方法来实现它，但只有在我返回 RootVC 时才推送事件触发.

I tried a lot of methods to make it, but pushing event fire only, when I return to my RootVC.

我试着和代表一起做:

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.我的错在哪里?

Please help to understand this behavior. Where is my mistake?

推荐答案

Error has been in other.如果我理解正确:在关闭呈现的视图控制器之前的一些动画会阻塞导航堆栈中的动画.我用两种方法解决了这个问题:

Error has been in other. If Im right understand: some animations before dismissing presented view controller are blocking animations in navigation stack. I solved this problem with 2 ways:

1) 在关闭前删除或设置正确的动画

1) deleteting or set right animations before dismissing

2) 在导航控制器中使用 setViewControllers(我选择它)

2) use setViewControllers in navigation controller (I select it)

- (void)dismissAndPush:(UIViewController *)vc {
    [self dismissViewControllerAnimated:NO completion:^{
        NSMutableArray *mutableControllers = [NSMutableArray arrayWithArray:self.navigationController.viewControllers];
        NSArray *controllers = [mutableControllers arrayByAddingObject:vc];
        [self.navigationController setViewControllers:controllers animated:NO];
    }];

}
