如何在iOS 8中检测自定义键盘扩展中的方向更改？ [英] How to detect Orientation Change in Custom Keyboard Extension in iOS 8?

问题描述

在自定义键盘扩展中，我们无法使用

In Custom Keyboard Extension , we can't use

`didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation` 

和 sharedApplication 。

我需要在旋转时检测键盘上的纵向或横向。

I need to detect portrait or landscape in keyboard when rotate.

如何在自定义键盘扩展中检测方向更改？

How can i detect when orientation change in Custom Keyboard extension?

推荐答案

为了在方向更改时更新自定义键盘，请在<$中覆盖 viewDidLayoutSubviews C $ C> UIInputViewController 。据我所知，当旋转发生时，总是调用此方法。

In order to update your custom keyboard when the orientation changes, override viewDidLayoutSubviews in the UIInputViewController. As far as I can tell, when a rotation occurs this method is always called.

此外，正如传统的 [UIApplication sharedApplication] statusBarOrientation] 不起作用，确定当前方向使用以下代码段：

Additionally, as the traditional [UIApplication sharedApplication] statusBarOrientation] doesn't work, to determine the current orientation use the following snippet:

if([UIScreen mainScreen].bounds.size.width < [UIScreen mainScreen].bounds.size.height){
    //Keyboard is in Portrait
}
else{
    //Keyboard is in Landscape
}

希望这有帮助！
