检测iOS中的旋转更改 [英] Detect rotation changes in iOS

问题描述

我正在制作一款需要在旋转时进行一点界面重新排列的iOS应用。我试图通过实现 - （void）orientationChanged：（NSNotification *）note 来检测这一点，但这会给我通知设备面朝上或面朝下的时间。

I am making an iOS app that needs to do a little interface rearrangement upon rotation. I am trying to detect this by implementing - (void)orientationChanged:(NSNotification *)note, but this gives me notifications for when the device is face up or face down.

我希望在界面改变方向时获得通知。

I want a way to just get notified when the interface changes orientations.

推荐答案

自iOS 8以来，上述方法已被弃用，处理和检测设备轮换的正确方法是：

Since iOS 8, above methods were deprecated, and the proper way to handle and detect device rotation is:

-(void）viewWillTransitionToSize：（CGSize）size withTransitionCoordinator：（id ）协调员;

要检测设备方向，您应该（根据文档）：调用 statusBarOrientation 方法确定设备方向

To detect device orientation, you should (according to documentation): call the statusBarOrientation method to determine the device orientation
