以编程方式在UILabel touchUpInside上执行操作? [英] Programmatically perform an action on UILabel touchUpInside?

问题描述

我有一堆通过代码添加的UILabel，并且如果用户的手指在内部触摸，我想为每个UILabel执行特定的操作(类似于IB中的UIButton的touchUpInside).最好的方法是什么?

I have a bunch of UILabels that I add through code and I want to perform a specific action for each if the user's finger touches up inside (much like UIButton's touchUpInside in IB). What is the best way of doing this?

推荐答案

最简单的方法可能是使用UIButton代替UILabel.自定义UIButton没有边框，看起来像普通标签，但可以为您处理事件跟踪.

The easiest way is probably to use UIButton instead of UILabel. A custom UIButton has no border and can look like a plain label, but handles the event tracking for you.

否则，您必须派生自UILabel并实现UIResponder调用以进行触摸处理.

Otherwise, you must derive from UILabel and implement the UIResponder calls for touch handling.
