UILabel：在标签上使用userInteractionEnabled方法 [英] UILabel: Using the userInteractionEnabled method on a label

问题描述

我想知道是否有人在UILabel上使用了userInteractionEnabled方法来允许标签像一个按钮（或者只是触发一个方法）。任何帮助将非常感谢。干杯！

I am wondering if anyone has used the userInteractionEnabled method on a UILabel to allow the label to act like a button (or just to fire off a method). Any help would be greatly appreciated. Cheers!

更新（4/30/09 @ 1：07pm）澄清：我有一个标准的InfoButton，在它旁边我想放置一个标签，设置，我想标签的功能像按钮（翻转到一个设置屏幕。所以，基本上我需要绑定已定义的showSettinsView到infoLabel标签;用户点击infoButton或infoLabel和方法触发。

Update (4/30/09 @1:07pm) Clarification: I have a standard InfoButton and next to it I want to place a label with the text "settings" and I would like the label to function like the button (which flips over to a settings screen. So, basically I need to tie the already defined showSettinsView to the "infoLabel" label; a user clicks on the infoButton or infoLabel and the method fires off.

infoButton已经工作，并且正在使用IBAction触发方法。我想知道如何连接标签来实现相同的方法

The infoButton is already working and is using an IBAction to trigger the method. I would like to know how to wire up the label to implement the same method. That is all. Cheers!

推荐答案

userInteractionEnabled 不是方法但是我想你会设置为 YES 允许事件通过 UIView

userInteractionEnabled is not a method but a property. But I think you will want to set this to YES to allow events to get through to the UIView superview.

您可能想要覆盖 touch的 touchesBegan：withEvent：包含您的 UIButton 和 UILabel 子视图

What you might want to do is override the touchesBegan:withEvent: method of the UIView that contains your UIButton and UILabel subviews.

在此方法中，测试 UITouch 触摸是否位于 UILabel 。

Within this method, test if any of the UITouch touches fall inside the bounds of the UILabel.

也就是说， CGPoint 元素 [touch locationInView] 与 CGRect 元素 [infoLabel bounds] 相交查看函数 CGRectContainsPoint 以运行此测试。

That is, does the CGPoint element [touch locationInView] intersect with with the CGRect element [infoLabel bounds]? Look into the function CGRectContainsPoint to run this test.

如果是这样，则触发 UIButton 。
