profileImageView。image = theImageView.image!.withRenderingMode(.alwaysTemplate) profileImageView。tintColor = uiccolor .green

OR

首先在图像资产中选择特定图像，然后选择红色作为模板而不是默认，然后写行。 profileImageView。tintColor = uiccolor .green

如果有人关心没有UIImageView的解决方案:

// (Swift 3)
extension UIImage {
    func tint(with color: UIColor) -> UIImage {
        var image = withRenderingMode(.alwaysTemplate)
        UIGraphicsBeginImageContextWithOptions(size, false, scale)
        color.set()

        image.draw(in: CGRect(origin: .zero, size: size))
        image = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return image
    }
}

利用Swift中的扩展:-

extension UIImageView {
    func changeImageColor( color:UIColor) -> UIImage
    {
        image = image!.withRenderingMode(.alwaysTemplate)
        tintColor = color
        return image!
    }
}

   //Change color of logo 
   logoImage.image =  logoImage.changeImageColor(color: .red)

用于着色UIButton的图像

let image1 = "ic_shopping_cart_empty"
btn_Basket.setImage(UIImage(named: image1)?.withRenderingMode(.alwaysTemplate), for: .normal)
btn_Basket.setImage(UIImage(named: image1)?.withRenderingMode(.alwaysTemplate), for: .selected)
btn_Basket.imageView?.tintColor = UIColor(UIColor.Red)

你可以在Swift 3中使用它，如果你有一个图像来替换清除按钮

func addTextfieldRightView(){

    let rightViewWidth:CGFloat = 30

    let viewMax = self.searchTxt.frame.height
    let buttonMax = self.searchTxt.frame.height - 16

    let buttonView = UIView(frame: CGRect(
        x: self.searchTxt.frame.width - rightViewWidth,
        y: 0,
        width: viewMax,
        height: viewMax))

    let myButton = UIButton(frame: CGRect(
        x: (viewMax - buttonMax) / 2,
        y: (viewMax - buttonMax) / 2,
        width: buttonMax,
        height: buttonMax))

    myButton.setImage(UIImage(named: "BlueClear")!, for: .normal)

    buttonView.addSubview(myButton)

    let clearPressed = UITapGestureRecognizer(target: self, action: #selector(SearchVC.clearPressed(sender:)))
    buttonView.isUserInteractionEnabled = true
    buttonView.addGestureRecognizer(clearPressed)

    myButton.addTarget(self, action: #selector(SearchVC.clearPressed(sender:)), for: .touchUpInside)

    self.searchTxt.rightView = buttonView
    self.searchTxt.rightViewMode = .whileEditing
}

我必须在Swift中使用扩展来做到这一点。

我想分享一下我是如何做到的:

extension UIImage {
    func imageWithColor(color1: UIColor) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        color1.setFill()

        let context = UIGraphicsGetCurrentContext() as CGContextRef
        CGContextTranslateCTM(context, 0, self.size.height)
        CGContextScaleCTM(context, 1.0, -1.0);
        CGContextSetBlendMode(context, CGBlendMode.Normal)

        let rect = CGRectMake(0, 0, self.size.width, self.size.height) as CGRect
        CGContextClipToMask(context, rect, self.CGImage)
        CGContextFillRect(context, rect)

        let newImage = UIGraphicsGetImageFromCurrentImageContext() as UIImage
        UIGraphicsEndImageContext()

        return newImage
    }
}

用法:

theImageView。image = theImageView.image.imageWithColor(uiccolor . redcolor ())

斯威夫特4

extension UIImage {
    func imageWithColor(color1: UIColor) -> UIImage {
        UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
        color1.setFill()

        let context = UIGraphicsGetCurrentContext()
        context?.translateBy(x: 0, y: self.size.height)
        context?.scaleBy(x: 1.0, y: -1.0)
        context?.setBlendMode(CGBlendMode.normal)

        let rect = CGRect(origin: .zero, size: CGSize(width: self.size.width, height: self.size.height))
        context?.clip(to: rect, mask: self.cgImage!)
        context?.fill(rect)

        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return newImage!
    }
}

用法:

theImageView。image = theImageView.image?imageWithColor (color1 UIColor.red):
