关闭UIBarButtonItem上的突出显示 [英] Turn off highlighting on UIBarButtonItem

问题描述

我正在尝试使用UIBarButtonItem在我的UIToolbar上添加标题。我使用简单的风格，看起来很好，但我似乎无法让它停止突出显示触摸。 突出显示时触摸选项不适用于条形按钮项目。有没有快速简便的方法来做到这一点？我正在尝试在界面构建器中进行构建，以便我可以看到我在做什么。我不想在视图中构建工具栏，每次都加载。

I'm trying to use a UIBarButtonItem to put a title on my UIToolbar. I'm using the plain style and that looks fine, but I can't seem to get it to stop highlighting on touch. The Shows Touch When Highlighted option isn't available for the bar button items. Is there a quick and easy way to do this? I'm trying to do the building in interface builder so I can see what I'm doing. I'd prefer not to build the toolbar in the view did load every time.

推荐答案

负责这个的属性可以在 UIButton 类：

The property responsible for this is accessible in the UIButton class:

myButton.showsTouchWhenHighlighted = NO;

您可以通过将UIButton分配给条形按钮项目的<$来在UIBarButtonItem中以编程方式访问它c $ c> customView 属性，并配置按钮。您也可以在Interface Builder中执行此操作：将UIButton拖到UIToolbar上，它会自动将它嵌入到UIBarButtonItem中 - 然后在按钮的设置下查找显示触摸突出显示复选框。

You can access this (programmatically) in a UIBarButtonItem by assigning a UIButton to the bar button item's customView property, and configuring the button. You can do this in Interface Builder too: drag a UIButton onto a UIToolbar, and it will automatically embed it in a UIBarButtonItem for you - then look for the "Shows Touch On Highlight" checkbox under the button's settings.

顺便说一下，我不知道你是如何自定义你的按钮所以随意忽略这一点，但如果你的按钮看起来像一个标准的工具栏项，那么用户会期望发光效果。

Incidentally, I don't know how you're customising your buttons so feel free to ignore this, but if your button looks and behaves like a standard toolbar item then users will expect the glow effect.
