iOS 8键盘在解除模态视图控制器后解除延迟 [英] iOS 8 Keyboard Dismissed delay after modal view controller is dismissed

问题描述

在iOS 8+中，我注意到如果你在一个视图控制器中有一个文本字段，当前是 firstResponder ，当视图控制器被解除时，键盘在被解雇之前，它会持续约1秒钟。

In iOS 8+ I noticed that if you have an textfield that is currently the firstResponder in a view controller that was presented, when the view controller is dismissed, the keyboard hangs around for around 1 second before being dismissed.

iOS 8.0和8.1以及不 7.1都会出现这种情况。

This occurs for both iOS 8.0 and 8.1 and not 7.1.

为什么会这样？

推荐答案

根据这个，在iOS 8中，似乎视图在实际屏幕外<= strong>之前不会重新响应第一响应者状态。

According to this, in iOS 8 it seems the view doesn’t resign first responder status until it’s actually offscreen.

我们的解决方法是在中调用 [self.view endEditing：YES] -viewWillDisappear 。

Our workaround is to call [self.view endEditing:YES] in -viewWillDisappear.
