iOS：如何在选项卡栏的UIImage中用另一种颜色替换特定颜色（选择和取消选择）？

当一种颜色被选中时，我想在我的UtiAbbar中将它替换为另一种颜色。目的是得到一个图像，我可以通过编程更改颜色

我怎么做

let tabBarItem = UITabBarItem(title: menuName, image: unselectedImage, selectedImage: selectedImage)  

我查了一下票没有成功：

我也面临同样的问题。您应该创建一个背景白色png，并将另一个图像放在顶部 具有半透明背景png

（我认为你应该使用质量更好的图片，因为你的图片看起来很奇怪）

您是否尝试过将渲染模式设置为.xccess中的Template或编程方式，并将着色颜色更改为渲染图像的imageView，或更改tabor tintColorWorks，谢谢。（对于图片，我会将您的评论转发给笔友：D）

                let iconWhite: UIImage? = self.load(fileName: "APP/icones/\(iconName).png")?.withRenderingMode(UIImage.RenderingMode.alwaysOriginal)
                        
                        
        //UNSELECT IMAGE
                        var unselectedImgBack = UIImage(named: "white.png")
                        var unselectedImgFront = iconWhite?.overlayImage(color: UIColor.black)
                        
                        let size = unselectedImgFront?.size
                        unselectedImgBack = unselectedImgBack?.resized(to: size!)
                        UIGraphicsBeginImageContext(size!)
                        let areaSize = CGRect(x: 0, y: 0, width: size!.width, height: size!.height)

                        let scanner2 = Scanner(string: color)
                        var value: UInt64 = 0

                            print("Hex: 0x\(String(value, radix: 16))")
                        }
                        selectedImgBack = selectedImgBack?.overlayImage(color: UIColor.init(rgb: Int(value)))

                        selectedImgBack = selectedImgBack?.resized(to: size!)
                        UIGraphicsBeginImageContext(size!)
                        selectedImgBack!.draw(in: areaSize)
                        selectedImgFront!.draw(in: areaSize, blendMode: .normal, alpha: 0.8)
                        selectedImgFront = UIGraphicsGetImageFromCurrentImageContext()!
                        UIGraphicsEndImageContext()
                        
                        let selectedImage = selectedImgFront!.withRenderingMode(UIImage.RenderingMode.alwaysOriginal)
