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)

在iOS 13及以上版本中，你可以简单地使用

let image = UIImage(named: "Heart")?.withRenderingMode(.alwaysTemplate)
if #available(iOS 13.0, *) {
   imageView.image = image?.withTintColor(UIColor.white)
}

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)

这里有一个类别应该可以做到这一点

@interface UIImage(Overlay)
@end

@implementation UIImage(Overlay)

- (UIImage *)imageWithColor:(UIColor *)color1
{
        UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
        CGContextRef context = UIGraphicsGetCurrentContext();
        CGContextTranslateCTM(context, 0, self.size.height);
        CGContextScaleCTM(context, 1.0, -1.0);
        CGContextSetBlendMode(context, kCGBlendModeNormal);
        CGRect rect = CGRectMake(0, 0, self.size.width, self.size.height);
        CGContextClipToMask(context, rect, self.CGImage);
        [color1 setFill];
        CGContextFillRect(context, rect);
        UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return newImage;
}
@end

所以你会这样做:

theImageView.image = [theImageView.image imageWithColor:[UIColor redColor]];

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
        }
    }

}

重绘图像的背景和填充颜色

extension UIImage {
  func withBackground(color: UIColor, fill fillColor: UIColor) -> UIImage {
    UIGraphicsBeginImageContextWithOptions(size, true, scale)
    
    guard let ctx = UIGraphicsGetCurrentContext(), let image = cgImage else { return self }
    defer { UIGraphicsEndImageContext() }
    
    ctx.concatenate(CGAffineTransform(a: 1, b: 0, c: 0, d: -1, tx: 0, ty: size.height))
    
    let rect = CGRect(origin: .zero, size: size)
    
    // draw background
    ctx.setFillColor(color.cgColor)
    ctx.fill(rect)
    
    // draw image with fill color
    ctx.clip(to: rect, mask: image)
    ctx.setFillColor(fillColor.cgColor)
    ctx.fill(rect)
    
    return UIGraphicsGetImageFromCurrentImageContext() ?? self
  }
}
