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

[解决办法]
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];
[解决办法]
[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]
[解决办法]
[self.navigationController popToRootViewControllerAnimated:YES]
