为了解决这个问题，我创建了一个Category来处理UIButtons的backgroundColor状态: ButtonBackgroundColor-iOS

您可以将类别安装为pod。

易于与Objective-C一起使用

@property (nonatomic, strong) UIButton *myButton;

...

[self.myButton bbc_backgroundColorNormal:[UIColor redColor]
                 backgroundColorSelected:[UIColor blueColor]];

甚至更容易使用Swift:

import ButtonBackgroundColor

...

let myButton:UIButton = UIButton(type:.Custom)

myButton.bbc_backgroundColorNormal(UIColor.redColor(), backgroundColorSelected: UIColor.blueColor())

我建议您导入豆荚:

platform :ios, '8.0'
use_frameworks!

pod 'ButtonBackgroundColor', '~> 1.0'

使用use_frameworks !在你的Podfile中使你更容易使用Swift和objective-C。

重要的

我还写了一篇博客来提供更多的信息。

试试这个!!!!

TouchedDown事件设置一种颜色，TouchUpInside设置另一种颜色。

- (IBAction)touchedDown:(id)sender {
    NSLog(@"Touched Down");
    btn1.backgroundColor=[UIColor redColor];
}

- (IBAction)touchUpInside:(id)sender {
    NSLog(@"TouchUpInside");
    btn1.backgroundColor=[UIColor whiteColor];    
}

简单的是只使用UIButton扩展

extension UIButton {

    func setBackgroundColor(color: UIColor, forState: UIControl.State) {
        self.clipsToBounds = true  // add this to maintain corner radius
        UIGraphicsBeginImageContext(CGSize(width: 1, height: 1))
        if let context = UIGraphicsGetCurrentContext() {
            context.setFillColor(color.cgColor)
            context.fill(CGRect(x: 0, y: 0, width: 1, height: 1))
            let colorImage = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()
            self.setBackgroundImage(colorImage, for: forState)
        }
    }

}

然后用这个

 optionButton.setBackgroundColor(color: UIColor(red:0.09, green:0.42, blue:0.82, alpha:1.0), forState: .selected)

 optionButton.setBackgroundColor(color: UIColor(red:0.96, green:0.96, blue:0.96, alpha:1.0), forState: .highlighted)

 optionButton.setBackgroundColor(color: UIColor(red:0.96, green:0.96, blue:0.96, alpha:1.0), forState: .normal)

你可以重写UIButton的setHighlighted方法。

objective - c

- (void)setHighlighted:(BOOL)highlighted {
    [super setHighlighted:highlighted];

    if (highlighted) {
        self.backgroundColor = UIColorFromRGB(0x387038);
    } else {
        self.backgroundColor = UIColorFromRGB(0x5bb75b);
    }
}

Swift 3.0和Swift 4.1

override open var isHighlighted: Bool {
    didSet {
        backgroundColor = isHighlighted ? UIColor.black : UIColor.white
    }
}

下面是Swift中选择按钮状态的代码:

func imageWithColor(color:UIColor) -> UIImage {
    let rect:CGRect = CGRectMake(0.0, 0.0, 1.0, 1.0)
     UIGraphicsBeginImageContext(rect.size)
    let context:CGContextRef = UIGraphicsGetCurrentContext()!
    CGContextSetFillColorWithColor(context, color.CGColor)
    CGContextFillRect(context, rect)
    let image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
    return image;
}

例子:

    self.button.setImage(self.imageWithColor(UIColor.blackColor()), forState: .Highlighted)

不确定这是否解决了你所追求的问题，或者是否符合你的总体开发环境，但我想尝试的第一件事是改变触地事件按钮的背景颜色。

选项1:

你需要捕捉两个事件，当用户按下按钮时UIControlEventTouchDown。UIControlEventTouchUpInside和UIControlEventTouchUpOutside将用于当它们释放按钮以返回正常状态时

UIButton *myButton =  [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setFrame:CGRectMake(10.0f, 10.0f, 100.0f, 20.f)];
[myButton setBackgroundColor:[UIColor blueColor]];
[myButton setTitle:@"click me:" forState:UIControlStateNormal];
[myButton setTitle:@"changed" forState:UIControlStateHighlighted];
[myButton addTarget:self action:@selector(buttonHighlight:) forControlEvents:UIControlEventTouchDown];
[myButton addTarget:self action:@selector(buttonNormal:) forControlEvents:UIControlEventTouchUpInside];

选项2:

返回你想要的高亮颜色的图像。这也可以是一个类别。

+ (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();

   return image;
}

然后更改按钮的高亮显示状态:

[myButton setBackgroundImage:[self imageWithColor:[UIColor greenColor]] forState:UIControlStateHighlighted];
