我有2个视图控制器以模态方式呈现.

A presents B which presents C.

当我解雇CI时也想解雇B. 但我不知道该怎么做:

解雇C:

[self dismissModalViewControllerAnimated:YES]
//[delegate dismissB] //this doesn't work either when i create a delegate pattern

现在我离开了B.如何从C中解雇B？

如何在Swift iOS中关闭2个视图控制器？

以下是我的代码.

@IBAction func backButtonTapped(sender: AnyObject) {
    self.presentingViewController
        .presentingViewController
        .dismissViewControllerAnimated(true, completion: nil)
}
