(IOS)设置UIButton高亮时的背景颜色

    // 方法一、子类化UIButton，重写setHighlighted:方法，代码如下

#import "WZBButton.h"

    @implementation WZBButton

    - (void)setHighlighted:(BOOL)highlighted {

        [supersetHighlighted:highlighted];

        UIColor *normalColor = [UIColor greenColor];

        UIColor *highlightedColor = [UIColor redColor];

        self.backgroundColor = highlighted ? highlightedColor : normalColor;

    }

    // 方法二、利用setBackgroundImage:forState:方法

    [button setBackgroundImage:[selfimageWithColor:[UIColor blueColor]] forState:UIControlStateHighlighted];

    - (UIImage *)imageWithColor:(UIColor *)color {

        CGRect rect = CGRectMake(0.0f,0.0f,1.0f,1.0f);

        UIGraphicsBeginImageContext(rect.size);

        CGContextRef context = UIGraphicsGetCurrentContext();

        CGContextSetFillColorWithColor(context, [color CGColor]);

        CGContextFillRect(context, rect);

        UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        returnimage;

    }
