UITableViewRowAction image for title

Question

I made a custom UITableViewRowAction. Now I\'d like to add an image instead of the text. I know that it\'s possible but don\'t know how to do it. Does someone of you knows

Answer 1

I just implement better version of https://stackoverflow.com/a/48122210 1. In majority of cases height of cell and width of custom swipe part are different, you have to calculate this in your function 2. Image can have different size than square, so you have to calculate proportions not just for height. So, code with my fixes

func setIcon(iconImage: UIImage, backColor: UIColor, cellHeight: CGFloat, customSwipPartWidth: CGFloat, iconSizePercentage: CGFloat) {
        let iconWidth = customSwipPartWidth * iconSizePercentage
        let iconHeight = iconImage.size.height / iconImage.size.width * iconWidth
        let marginY = (cellHeight - iconHeight) / 2 as CGFloat
        let marginX = (customSwipPartWidth - iconWidth) / 2 as CGFloat


        UIGraphicsBeginImageContextWithOptions(CGSize(width: customSwipPartWidth, height: cellHeight), false, 0)
        let context = UIGraphicsGetCurrentContext()

        backColor.setFill()
        context!.fill(CGRect(x:0, y:0, width:customSwipPartWidth, height:cellHeight))

        iconImage.draw(in: CGRect(x: marginX, y: marginY, width: iconWidth, height: iconHeight))

        let actionImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

        self.backgroundColor = UIColor.init(patternImage: actionImage!)
    }
