let commentImageView = UIImageView(frame: CGRectMake(100, 100, 100, 100))
commentImageView.image = UIImage(named: "myimage.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
commentImageView.tintColor = UIColor.blackColor()
addSubview(commentImageView)

与迅速

let commentImageView = UIImageView(frame: CGRectMake(100, 100, 100, 100))
commentImageView.image = UIImage(named: "myimage.png")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
commentImageView.tintColor = UIColor.blackColor()
addSubview(commentImageView)

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)

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。

这是一个简单的扩展，适用于Swift 5:

extension UIImageView {

func setImageTintColor(_ color: UIColor) {
    let tintedImage = self.image?.withRenderingMode(.alwaysTemplate)
    self.image = tintedImage
    self.tintColor = color
  }
}

用法:

myImageView.setImageTintColor(.systemBlue)

另外，对于以上的答案，在iOS 13及以后有一个干净的方法

let image = UIImage(named: "imageName")?.withTintColor(.white, renderingMode: .alwaysTemplate)
