iOS8 Extension中横竖屏Notification问题

问题描述：输入法Extension中使用Notification监听UIApplicationDidChangeStatusBarOrientationNotification，发现userInfo中返回转屏前方向

问题分析：使用self.interfaceOrientation发现同样返回的是转屏前方向。查了下文档，发现：

UIApplicationWillChangeStatusBarOrientationNotification
Posted when the app is about to change the orientation of its interface.

UIApplicationDidChangeStatusBarOrientationNotification
Posted when the orientation of the app’s user interface changes.

问题解决：替换为UIApplicationWillChangeStatusBarOrientationNotification监听事件，返回正常

PS：Xcode6 beta5, iOS8 ,Keyboard Extension
