现在我使用基于Duncan Babbage response的方法:

+ (UIImageView *) tintImageView: (UIImageView *)imageView withColor: (UIColor*) color{
    imageView.image = [imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
    [imageView setTintColor:color];
    return imageView;
}

let navHeight = self.navigationController?.navigationBar.frame.height;
let menuBtn = UIButton(type: .custom)
menuBtn.frame = CGRect(x: 0, y: 0, width: 45, height: navHeight!)     
menuBtn.setImage(UIImage(named:"image_name")!.withRenderingMode(.alwaysTemplate), for: .normal)        
menuBtn.tintColor = .black

在故事板和图像资产中。你也可以改变这两个:

更新渲染模式为模板图像

更新视图中的色调颜色。

如果您有SVG图像的任何id，您可以根据id填充颜色。

    let image = SVGKImage(named: "iconName")
    let svgIMGV = SVGKFastImageView(frame: self.imgView.frame)
         svgIMGV.image = image
          svgIMGV.fillTintColor(colorImage: UIColor.red, iconID: "Bank")

// Add in extension SVGKImageView
extension SVGKImageView {
 func fillTintColor(colorImage: UIColor, iconID: String) {
        if self.image != nil && self.image.caLayerTree != nil {
            print(self.image.caLayerTree.sublayers)
            guard let sublayers = self.image.caLayerTree.sublayers else { return }
            fillRecursively(sublayers: sublayers, color: colorImage, iconID: iconID)
        }
    }

     private func fillRecursively(sublayers: [CALayer], color: UIColor, iconID: String, hasFoundLayer: Bool) {
        var isLayerFound = false
        for layer in sublayers {
            if let l = layer as? CAShapeLayer {

                print(l.name)                
                //IF you want to color the specific shapelayer by id else remove the l.name  == "myID"  validation
                if let name =  l.name,  hasFoundLayer == true && name == "myID" {
                    self.colorThatImageWIthColor(color: color, layer: l)
                    print("Colouring FInished")
                }
            } else {
                if layer.name == iconID {
                    if let innerSublayer = layer.sublayers as? [CAShapeLayer] {
                        fillRecursively(sublayers: innerSublayer, color: color, iconID: iconID, hasFoundLayer: true )
                        print("FOund")
                    }
                } else {
                    if let l = layer as? CALayer, let sub = l.sublayers {
                        fillRecursively(sublayers: sub, color: color, iconID: iconID, hasFoundLayer: false)
                    }
                }
            }

        }
    }

    func colorThatImageWIthColor(color: UIColor, layer: CAShapeLayer) {
        if layer.strokeColor != nil {
            layer.strokeColor = color.cgColor
        }
        if layer.fillColor != nil {
            layer.fillColor = color.cgColor
        }
    }

}

或者签出这个例子。

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)

自iOS 13以来，UIImage有一个原生方法

let image = yourImage.withTintColor(.systemRed)
