Question

[self.navigationController pushViewController:ControlView1 animated:YES];[self.navigationController pushViewController:ControlView2  animated:YES];
[self.navigationController pushViewController:ControlView3  animated:YES];父页面连续push3个view 。如何从ControlView3  返回父页面？  把ControlView1 ControlView2  ControlView3 都pop出去。然后调用父页面的一个方法，刷新父页面

Answer 1

用到委托。你可以在ControlView3里定义一个委托。从ControlView3里退出的地方调用这个委托。ControlView3的委托在父页面实现。实现的内容就是：[self.navigationController popViewControlleranimated:YES];[self.navigationController popViewControlleranimated:YES];
[self.navigationController popViewControlleranimated:YES];

Answer 2

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:你父页面的位置，我感觉你可以填0] animated:YES];如果你说的父页面是根基视图的话也可以这样：[self.navigationController popToRootViewControllerAnimated:YES]

Answer 3

[self.navigationController popToRootViewControllerAnimated:YES]
