How can I add the 'Glow effect' to UIBarBu

问题:

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)

回答1:

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

So...

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

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.

Have you tried

- (id)initWithImage:(UIImage *)image style:(UIBarButtonItemStyle)style target:(id)target action:(SEL)action

as button style using UIBarButtonItemStylePlain
