在UIScrollView中关闭键盘 [英] Dismissing the keyboard in a UIScrollView

问题描述

好吧，我在 UIScrollView中有几个 UITextFields 和 UITextViews ，我想在触摸或滚动 scrollview 时将键盘设置为消失（除非在文本字段/视图中触及时，当然）。

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).

我目前尝试这样做是用子类替换 UIScrollView ，并将其设置为在 touchesBegan 方法中调用removeKeyboard函数（在主视图控制器中定义）。但是，这只会移除键盘以进行正常触摸，而不是仅在滚动视图时。那么，在 UIScrollView 中删除​​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的的最简洁方法。

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

scrollView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;

或

scrollView.keyboardDismissMode = UIScrollViewKeyboardDismissModeInteractive;

Swift：

scrollView.keyboardDismissMode = .onDrag

或

scrollView.keyboardDismissMode = .interactive
