问题描述

我想为用户触摸设置 UIButton 禁用。 setEnabled setUserInteractionEnabled 都可以执行此操作。哪个更好?它们有何不同?

I want to make a UIButton disable for user touch. Both setEnabled and setUserInteractionEnabled can do this. Which is better? How are they different?

推荐答案

已启用属于 UIControl ,这是 UIButton 的超类。 userInteractionEnabled UIView 的属性(这是 UIControl )。 启用会对对象的可视状态产生影响(默认情况下显示为灰色),并且通常是禁用控件 - 视觉反馈的首选方法,指示行为是一件好事。

enabled is a property of UIControl, which is the superclass for UIButton. userInteractionEnabled is a property of UIView (which is the superclass of UIControl). enabled has effects on the visual state of the object (grayed out, by default) and is generally the preferred method of disabling a control—visual feedback indicating behaviors is a good thing.

除此之外没有太多实际的结果。与控件交互的代码更有可能检查按钮是否已启用,而不是设置了userInteractionEnabled属性;它更传统。

There's not much practical upshot beyond that. Code that interacts with your controls is more likely to check if buttons are enabled than if their userInteractionEnabled property is set; it's more conventional.
