UIButton发光效果 [英] UIButton glow effect

问题描述

我需要有关UIButtons的帮助，

I need some help with UIButtons,

我想知道如何获得我在下面的代码中设置的发光效果，以响应触摸的位置.

I was wondering how to get the glow effect that I set with the code below to respond to where the touch is.

[C setShowsTouchWhenHighlighted:YES];

想法是，当触摸按钮时，它将跟随触摸的位置.

The idea is that when the button is touched it will follow where the touch is.

推荐答案

您必须自己执行此操作.将glow png加载到UIImageView中，并将其添加到视图层次结构中.然后根据触摸设置视图的位置.

You have to do this yourself. Load a glow png into a UIImageView and add it into the view hierarchy. Then set the view's position based on touches.
