长按 UIButton [英] Long pressed UIButton

问题描述

我想知道如果有人按住 UIButton 键的时间过长，我是否可以捕获 UIButton 的事件(通过通知或其他某种机制)；比按一次按钮还要长 - 假设有人按住按钮几秒钟......

I was wondering if I could capture an event (via Notification or some other mechanism), of a UIButton if somebody is holding the key pressing a UIButton for an excessive period of time; longer than a single button push - let's say somebody that holds the button pressed for a few seconds...

谢谢.

推荐答案

您可以添加 UILongPressGestureRecognizer 到您的按钮，在其 initWithTarget:action: 中传递一个选择器code>，并通过设置其 minimumPressDuration 属性来选择持续时间.

You can add UILongPressGestureRecognizer to your button, pass a selector in its initWithTarget:action:, and choose the duration time by setting its minimumPressDuration property.
