在模态视图中,在PresentViewController不工作之后DismissViewControllerAnimated

Question

我在做一些测试时遇到了这个问题.我提出了一个名为ModalView1的模态视图.在ModalView1中,当按下一个按钮时,将使用另一个Modal视图,称为ModalView2 presentViewController.然后我尝试解雇ModalView2 dismissViewControllerAnimated但它无法正常工作.
这是按钮操作中的代码片段

- (void) buttonAction: (UIButton*) sender
{
    ModalView *ModalView2 = [[ModalView alloc] init];
    [self presentViewController:ModalView2 animated:YES completion:nil];
    [self dismissViewControllerAnimated:YES completion:nil];
}

任何帮助将非常感激.谢谢.

目前尚不清楚你要做什么.我给你两个选择:

呈现ModalView2然后解雇ModalView2(对我没有意义,但这是我在你的问题中可以阅读的内容)

- (void) buttonAction: (UIButton*) sender {
    ModalView* modalView2 = [[ModalView alloc] init];
    [self presentViewController:modalView2 animated:YES completion:^{
        [modalView2 dismissViewControllerAnimated:YES completion:nil];
    }];
}

演示ModalView2并解除ModalView1:

- (void) buttonAction: (UIButton*) sender {
    ModalView* modalView2 = [[ModalView alloc] init];
    UIViewController* presentingViewController = self.presentingViewController;
    [self dismissViewControllerAnimated:YES completion:^{
        [presentingViewController presentViewController:modalView2 animated:YES completion:nil];
    }];
}
