如何将“发光效果"添加到 UIBarButtonItem? [英] How can I add the 'Glow effect' to UIBarButtonItem?

问题描述

我尝试了很多方法来找出 UIBarButtonItem 的发光效果.现在正在创建一个 UIButton 并将其作为 UIBarButton 的 customView.有没有人有任何其他方法可以使它更容易?(就像 UIBarButtonItem 的内置属性)

I tried a lot to find out the glow effect for UIBarButtonItem. Now am doing by creating a UIButton and making it as the customView for the UIBarButton. Do anyone have any other methods to make it much more easier? (like a inbuilt property for UIBarButtonItem)

推荐答案

你的意思是当你触摸一个按钮时得到的效果?这是 UIButton 上的一个属性(也可以从 Interface Builder 访问)；

You mean the effect you get when you touch an button? That is a property on an UIButton (also accessible from Interface Builder);

@property(nonatomic) BOOL showsTouchWhenHighlighted

所以...

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.showsTouchWhenHighlighted = YES;

如果您编写 UIBarButtonItem 的子类并将此代码放在某个地方，那么重用它真的很容易(而且不会乱七八糟).不知道有没有其他办法.

If you write a subclass of UIBarButtonItem and put this code in there somewhere it is really easy (and not messy) to re-use it. I'm not sure if there is any other way.
