模态视图控制器不调用呈现视图控制器的dismissModalViewControllerAnimated：方法 [英] modal view controller not calling presenting view controller's dismissModalViewControllerAnimated: method

问题描述

在我的模态视图控制器中，我有一个按钮处理方法，包括

In my modal view controller I have a button handling method that includes

[self dismissModalViewControllerAnimated: YES];

在呈现视图控制器中，我重写dismissModalViewControllerAnimated：如下所示：

In the presenting view controller I override dismissModalViewControllerAnimated: as follows:

-(void) dismissModalViewControllerAnimated: (BOOL)animated
{
  NSLog(@"dismiss");
  [super dismissModalViewControllerAnimated: animated];
}

触摸按钮时，会调用按钮处理方法，但是dismissModalViewControllerAnimated ：覆盖似乎没有被调用：NSLog（@dismiss）;语句未被调用，方法内的断点不会被命中。

When the button is touched, the button handling method gets called, but the dismissModalViewControllerAnimated: override does not seem to get called: the NSLog(@"dismiss"); statement isn't called, and a breakpoint inside the method doesn't get hit.

我试过

[[self presentingViewController] dismissModalViewControllerAnimated: YES];

但这也不起作用。但是，模态视图控制器确实被解雇了。

but that didn't work either. However, the modal view controller does get dismissed.

知道可能出现什么问题吗？

Any idea what might be going wrong?

推荐答案

呈现模态视图控制器的代码包含在UIViewController中，而UIViewController又包含在UINavigationController中。当我打电话

The code that presented the modal view controller was contained in a UIViewController, which was in turn contained in a UINavigationController. When I called

[[self presentingViewController] dismissModalViewControllerAnimated: YES];

或

[self dismissModalViewControllerAnimated: YES];

解雇消息被发送到UINavigationController对象。

the dismissal message was being sent to the UINavigationController object.
