如何突出显示UIButton的背景颜色?

时间:2013-01-25 14:04:23

标签: ios objective-c xcode uibutton

在我的应用中的某个时刻,我有一个突出显示的UIButton(例如,当用户将手指放在按钮上时),我需要在按钮突出显示时更改背景颜色(所以用户仍在按钮上。

我尝试了以下内容:

_button.backgroundColor = [UIColor redColor];

但它不起作用。颜色保持不变。当按钮没有突出显示时我尝试了相同的代码,它工作正常。我也尝试在更改颜色后调用-setNeedsDisplay,它没有任何效果。

如何强制按钮更改背景颜色?

您可以覆盖UIButton的{​​{1}}方法。

Objective-C

setHighlighted

Swift 3.0和Swift 4.1

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

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

不确定这种解决方案是否能解决您的问题,或者是否适合您的一般开发环境,但我要尝试的第一件事就是更改touchDown事件中按钮的背景颜色。

选项1:

您需要捕获两个事件,当用户按下按钮时,UIControlEventTouchDown将用于捕获。 UIControlEventTouchUpInside和UIControlEventTouchUpOutside将在他们释放按钮时将其恢复到正常状态

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:

返回由您想要的高光颜色制作的图像。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;
}

然后更改按钮的突出显示状态:

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

答案 2 :(得分:92)

无需将highlighted覆盖为计算属性。您可以使用属性观察器来触发背景颜色更改:

override var highlighted: Bool {
    didSet {
        backgroundColor = highlighted ? UIColor.lightGrayColor() : UIColor.whiteColor()
    }
}

Swift 4

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

答案 3 :(得分:45)

在Swift中,您可以覆盖突出显示(或选定)属性的访问者,而不是覆盖setHighlighted方法

override var highlighted: Bool {
        get {
            return super.highlighted
        }
        set {
            if newValue {
                backgroundColor = UIColor.blackColor()
            }
            else {
                backgroundColor = UIColor.whiteColor()
            }
            super.highlighted = newValue
        }
    }

Swift中一个方便的通用扩展:

extension UIButton {
    private func imageWithColor(color: UIColor) -> UIImage {
        let rect = CGRectMake(0.0, 0.0, 1.0, 1.0)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()

        CGContextSetFillColorWithColor(context, color.CGColor)
        CGContextFillRect(context, rect)

        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return image
    }

    func setBackgroundColor(color: UIColor, forUIControlState state: UIControlState) {
        self.setBackgroundImage(imageWithColor(color), forState: state)
    }
}

Swift 3.0

extension UIButton {
    private func imageWithColor(color: UIColor) -> UIImage? {
        let rect = CGRect(x: 0.0, y: 0.0, width: 1.0, height: 1.0)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()

        context?.setFillColor(color.cgColor)
        context?.fill(rect)

        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return image
    }

    func setBackgroundColor(_ color: UIColor, for state: UIControlState) {
        self.setBackgroundImage(imageWithColor(color: color), for: state)
    }
}

覆盖突出显示的变量。 添加@IBInspectable可以让您在故事板中编辑突出显示的backgroundColor,这也非常棒。

class BackgroundHighlightedButton: UIButton {
    @IBInspectable var highlightedBackgroundColor :UIColor?
    @IBInspectable var nonHighlightedBackgroundColor :UIColor?
    override var highlighted :Bool {
        get {
            return super.highlighted
        }
        set {
            if newValue {
                self.backgroundColor = highlightedBackgroundColor
            }
            else {
                self.backgroundColor = nonHighlightedBackgroundColor
            }
            super.highlighted = newValue
        }
    }
}

更紧凑的解决方案(基于 @ aleksejs-mjaliks 答案):

Swift 3/4 +

override var isHighlighted: Bool {
    didSet {
        backgroundColor = isHighlighted ? .lightGray : .white
    }
}

斯威夫特2:

override var highlighted: Bool {
    didSet {
        backgroundColor = highlighted ? UIColor.lightGrayColor() : UIColor.whiteColor()
    }
}

如果你不想覆盖,这是 @ timur-bernikowich 的答案的更新版本( Swift 4.2 ):

extension UIButton {
  func setBackgroundColor(_ color: UIColor, forState controlState: UIControl.State) {
    let colorImage = UIGraphicsImageRenderer(size: CGSize(width: 1, height: 1)).image { _ in
      color.setFill()
      UIBezierPath(rect: CGRect(x: 0, y: 0, width: 1, height: 1)).fill()
    }
    setBackgroundImage(colorImage, for: controlState)
  }
}

UIButton扩展名为 Swift 3 + 语法:

extension UIButton {
    func setBackgroundColor(color: UIColor, forState: UIControlState) {
        UIGraphicsBeginImageContext(CGSize(width: 1, height: 1))
        UIGraphicsGetCurrentContext()!.setFillColor(color.cgColor)
        UIGraphicsGetCurrentContext()!.fill(CGRect(x: 0, y: 0, width: 1, height: 1))
        let colorImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        self.setBackgroundImage(colorImage, for: forState)

这是Swift中的一种方法,使用UIButton扩展来添加IBInspectable,名为highlightedBackgroundColor。与子类化类似,不需要子类。

private var HighlightedBackgroundColorKey = 0
private var NormalBackgroundColorKey = 0

extension UIButton {

    @IBInspectable var highlightedBackgroundColor: UIColor? {
        get {
            return objc_getAssociatedObject(self, &HighlightedBackgroundColorKey) as? UIColor
        }

        set(newValue) {
            objc_setAssociatedObject(self,
                &HighlightedBackgroundColorKey, newValue, UInt(OBJC_ASSOCIATION_RETAIN))
        }
    }

    private var normalBackgroundColor: UIColor? {
        get {
            return objc_getAssociatedObject(self, &NormalBackgroundColorKey) as? UIColor
        }

        set(newValue) {
            objc_setAssociatedObject(self,
                &NormalBackgroundColorKey, newValue, UInt(OBJC_ASSOCIATION_RETAIN))
        }
    }

    override public var backgroundColor: UIColor? {
        didSet {
            if !highlighted {
                normalBackgroundColor = backgroundColor
            }
        }
    }

    override public var highlighted: Bool {
        didSet {
            if let highlightedBackgroundColor = self.highlightedBackgroundColor {
                if highlighted {
                    backgroundColor = highlightedBackgroundColor
                } else {
                    backgroundColor = normalBackgroundColor
                }
            }
        }
    }
}

我希望这会有所帮助。

Swift 3 + 的最佳解决方案,无需子类化。

extension UIButton {
  func setBackgroundColor(_ color: UIColor, for state: UIControlState) {
    let rect = CGRect(x: 0, y: 0, width: 1, height: 1)
    UIGraphicsBeginImageContext(rect.size)
    color.setFill()
    UIRectFill(rect)
    let colorImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    setBackgroundImage(colorImage, for: state)
  }
}

使用此扩展程序,可以轻松管理不同状态的颜色,如果没有提供突出显示的颜色,它会自动淡化您的正常颜色。

对UIButton进行子类化并添加可检查的属性以方便使用(用Swift 3.0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

更新:

使用UIButtonBackgroundColor Swift库。

OLD:

使用下面的帮助程序创建一个带有灰度填充颜色的1 px x 1像素图像:

UIImage *image = ACUTilingImageGray(248/255.0, 1);

或RGB填充颜色:

UIImage *image = ACUTilingImageRGB(253/255.0, 123/255.0, 43/255.0, 1);

然后,使用image设置按钮的背景图像:

[button setBackgroundImage:image forState:UIControlStateNormal];

助手

#pragma mark - Helpers

UIImage *ACUTilingImageGray(CGFloat gray, CGFloat alpha)
{
    return ACUTilingImage(alpha, ^(CGContextRef context) {
        CGContextSetGrayFillColor(context, gray, alpha);
    });
}

UIImage *ACUTilingImageRGB(CGFloat red, CGFloat green, CGFloat blue, CGFloat alpha)
{
    return ACUTilingImage(alpha, ^(CGContextRef context) {
        CGContextSetRGBFillColor(context, red, green, blue, alpha);
    });
}

UIImage *ACUTilingImage(CGFloat alpha, void (^setFillColor)(CGContextRef context))
{
    CGRect rect = CGRectMake(0, 0, 0.5, 0.5);
    UIGraphicsBeginImageContextWithOptions(rect.size, alpha == 1, 0);
    CGContextRef context = UIGraphicsGetCurrentContext();
    setFillColor(context);
    CGContextFillRect(context, rect);
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

简单就是只使用该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)
        }
    }

}

并使用

 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)

为了解决这个问题,我创建了一个类别来处理backgroundColor国家UIButtons
ButtonBackgroundColor-iOS

您可以将类别安装为pod

易于使用 Objective-C

@property (nonatomic, strong) UIButton *myButton;

...

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

使用 Swift

更容易使用
import ButtonBackgroundColor

...

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

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

我建议你导入pod:

platform :ios, '8.0'
use_frameworks!

pod 'ButtonBackgroundColor', '~> 1.0'

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

您可以继承UIButton并创建一个很好的forState。

<强> colourButton.h

#import <UIKit/UIKit.h>

@interface colourButton : UIButton

-(void)setBackgroundColor:(UIColor *)backgroundColor forState:(UIControlState)state;

@end

<强> colourButton.m

#import "colourButton.h"

@implementation colourButton
{
    NSMutableDictionary *colours;
}

-(id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];

    // If colours does not exist
    if(!colours)
    {
        colours = [NSMutableDictionary new];  // The dictionary is used to store the colour, the key is a text version of the ENUM
        colours[[NSString stringWithFormat:@"%lu", UIControlStateNormal]] = (UIColor*)self.backgroundColor;  // Store the original background colour
    }

    return self;
}

-(void)setBackgroundColor:(UIColor *)backgroundColor forState:(UIControlState)state
{
    // If it is normal then set the standard background here
    if(state & UIControlStateNormal)
    {
        [super setBackgroundColor:backgroundColor];
    }

    // Store the background colour for that state
    colours[[NSString stringWithFormat:@"%lu", state]]= backgroundColor;
}

-(void)setHighlighted:(BOOL)highlighted
{
    // Do original Highlight
    [super setHighlighted:highlighted];

    // Highlight with new colour OR replace with orignial
    if (highlighted && colours[[NSString stringWithFormat:@"%lu", UIControlStateHighlighted]])
    {
        self.backgroundColor = colours[[NSString stringWithFormat:@"%lu", UIControlStateHighlighted]];
    }
    else
    {
        self.backgroundColor = colours[[NSString stringWithFormat:@"%lu", UIControlStateNormal]];
    }
}

-(void)setSelected:(BOOL)selected
{
    // Do original Selected
    [super setSelected:selected];

    // Select with new colour OR replace with orignial
    if (selected && colours[[NSString stringWithFormat:@"%lu", UIControlStateSelected]])
    {
        self.backgroundColor = colours[[NSString stringWithFormat:@"%lu", UIControlStateSelected]];
    }
    else
    {
        self.backgroundColor = colours[[NSString stringWithFormat:@"%lu", UIControlStateNormal]];
    }
}

@end

备注(这是一个例子,我知道有问题,这里有一些)

我使用NSMutableDictionay为每个状态存储UIColor,我必须为Key做一个令人讨厌的文本转换,因为UIControlState不是一个很好的直接Int。如果你可以在那里使用那么多对象初始化一个数组并使用State作为索引。

因此,你很多人都有困难,例如一个选定的&amp;禁用按钮,需要更多逻辑。

另一个问题是,如果您尝试同时设置多种颜色,我没有尝试使用按钮,但如果您可以这样做,它可能无法正常工作

 [btn setBackgroundColor:colour forState:UIControlStateSelected & UIControlStateHighlighted];

我假设这是StoryBoard,没有init,initWithFrame,所以如果你需要它们就添加它们。

在Swift 5中

对于那些不想使用彩色背景来击败选定状态的人

您可以使用#Selector和if语句轻松地分别更改每种状态的UIButton颜色来解决问题

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

    }
}
