modalviewcontroller

问题 I have a modal view controller which displays a navigation controller. The navigation controller in-turn has a regular UIViewController as its root view controller. The only UI element that the above-mentioned UIViewController has is a UISwitch. Now here's the problem: When I change the barStyle property of the navigation controller, the layout of the UISwitch inside the UIViewController changes.
