关闭 UIScrollView 中的键盘

问题描述

好的，我在 UIScrollView 中有几个 UITextFields 和 UITextViews，我想将键盘设置为随时消失scrollview 被触摸或滚动(当然，当您在文本字段/视图内触摸时除外).

Alright, I have a couple of UITextFields and UITextViews inside a UIScrollView, and I'd like to set the keyboard to disappear whenever the scrollview is touched or scrolled (except when you touch down inside the text field/view, of course).

我目前的尝试是将 UIScrollView 替换为子类，并将其设置为在 touchesBegan 内调用 removeKeyboard 函数(在主视图控制器内定义)方法.但是，这只会在正常触摸时移除键盘，而不是在简单地滚动视图时.那么，在 UIScrollView 中移除键盘的最佳方法是什么?

My current attempt at doing this is replacing the UIScrollView with a subclass, and setting it to call a removeKeyboard function (defined inside the main view controller) inside the touchesBegan method. However, this only removes the keyboard for a normal touch, not when the view is simply scrolled. So, what's the best way to remove the keyboard inside a UIScrollView?

提前感谢您的帮助.

推荐答案

这是在 iOS 7.0 及更高版本中实现此目标的最简洁方法.

Here is the cleanest way to achieve this in iOS 7.0 and above.

scrollView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;

或者

scrollView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

在斯威夫特中:

scrollView.keyboardDismissMode = .onDrag

或者

scrollView.keyboardDismissMode = .interactive
