Change tint color of SVG #24

Closed haashem closed 8 years ago

haashem commented 8 years ago

how can I change tint color of my SVG file? I load the render to an SVGRenderLayer.

let svgRender = SVGRenderer(contentsOfURL: NSURL(string: "http://static.foodiran.com/resource/app/nayeb/cat/1412.svg")!)
            svgRender.setCurrentColor(UIColor.greenColor())
            let svgLayer = SVGRendererLayer()
            svgLayer.bounds = svgRender.viewRect;
            svgLayer.backgroundColor = UIColor.cyanColor().CGColor
            svgLayer.defaultColor = UIColor.greenColor()
            svgRender.setCurrentColor(UIColor.greenColor())
            svgLayer.renderer = svgRender
            self.vectorView.layer.addSublayer(svgLayer)
            svgLayer.position = CGPointMake(self.vectorView.width/2, self.vectorView.height/2.0)

First of all, you have to mark the SVG to use a current color instead of a hard coded color. So <path fill="#020202" becomes <path fill="currentColor"

Also, I should say that I've never tested the library against remote URLs.

what a trick! mention it in README thanks for quick answer!

Again I'd highly recommend against using the renderer in this way, as it will make synchronous network calls. I'd download the file locally and then set up the renderer.
