使用CocoaPods添加到Podfile

pod "UIButtonSetBackgroundColorForState"

斯威夫特

button.setBackgroundColor(.red, forState: .highlighted)

objective - c

[button setBackgroundColor:[UIColor redColor] forState:UIControlStateHighlighted];

子类化UIButton并添加可检查的属性以方便使用(在Swift 3.0中编写):

final class SelectableBackgroundButton: UIButton {

    private struct Constants {
        static let animationDuration: NSTimeInterval = 0.1
    }

    @IBInspectable
    var animatedColorChange: Bool = true

    @IBInspectable
    var selectedBgColor: UIColor = UIColor.blackColor().colorWithAlphaComponent(0.2)

    @IBInspectable
    var normalBgColor: UIColor = UIColor.clearColor()

    override var selected: Bool {
        didSet {
            if animatedColorChange {
                UIView.animateWithDuration(Constants.animationDuration) {
                    self.backgroundColor = self.selected ? self.selectedBgColor : self.normalBgColor
                }
            } else {
                self.backgroundColor = selected ? selectedBgColor : normalBgColor
            }
        }
    }

    override var highlighted: Bool {
        didSet {
            if animatedColorChange {
                UIView.animateWithDuration(Constants.animationDuration) {
                    self.backgroundColor = self.highlighted ? self.selectedBgColor : self.normalBgColor
                }
            } else {
                self.backgroundColor = highlighted ? selectedBgColor : normalBgColor
            }
        }
    }
}

class CustomButton: UIButton {

    override var isHighlighted: Bool {
        didSet {
            if (isHighlighted) {
                alpha = 0.5
            }
            else {
                alpha = 1
            }            
        }
    }

}

在Swift 5中

对于那些不想使用彩色背景击败所选状态的人

简单地说，你可以通过使用#Selector & if语句轻松地为每个状态单独更改UIButton颜色来解决这个问题

例如:

    override func viewDidLoad() {
    super.viewDidLoad()
    self.myButtonOutlet.backgroundColor = UIColor.white  //to reset the button color to its original color ( optionally )
}

@IBOutlet weak var myButtonOutlet: UIButton!{
    didSet{  // Button selector and image here
        self.myButtonOutlet.setImage(UIImage(systemName: ""), for: UIControl.State.normal)

        self.myButtonOutlet.setImage(UIImage(systemName: "checkmark"), for: UIControl.State.selected)



        self.myButtonOutlet.addTarget(self, action: #selector(tappedButton), for: UIControl.Event.touchUpInside)
    }
}

@objc func tappedButton() {  // Colors selection is here
    if self.myButtonOutlet.isSelected == true {

        self.myButtonOutlet.isSelected = false
        self.myButtonOutlet.backgroundColor = UIColor.white         
    } else {
        self.myButtonOutlet.isSelected = true

        self.myButtonOutlet.backgroundColor = UIColor.black
        self.myButtonOutlet.tintColor00 = UIColor.white

    }
}

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];

如果你不重写 只需要设置两个动作 触地得分 touchUpInside
