推荐答案

RSSReaderMaker解决方案可用于较小的更新Swift 5:

RSSReaderMaker solution work with small updates Swift 5:

class ImageWithoutRender: UIImage {
    override func withRenderingMode(_ renderingMode: UIImage.RenderingMode) -> UIImage {
        return self
    }
}

在trailingSwipeActionsConfigurationForRowAt或leadingSwipeActionsConfigurationForRowAt

使用:

if let cgImageX =  UIImage(named: "x_blue_big")?.cgImage {
     action.image = ImageWithoutRender(cgImage: cgImageX, scale: UIScreen.main.nativeScale, orientation: .up)
}
