I have a UIImage that is a small symbol that is all black. The UIImage is getting set in a custom UIButton subclass I have. Is it possible to have the image to apply the tintColor to it, so instead of the black image it changes colors to whatever the tintColor is?
I'm just trying to avoid creating new assets.
// here I want defaultImageName (that is black) to use the tintColor (that is white) [self setImage:[UIImage imageNamed:defaultImageName] forState:UIControlStateNormal];

setBlendMode(. multiply) ctx. draw(image. cgImage!, in: imageRect) let newImage = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() return newImage! } }
UIImage *img = [[UIImage alloc] init]; [img setImage:[UIImage imageNamed:@"anyImageName"]];
If you are just supporting iOS 7 you can use tintColor and UIImageRenderingModeAlwaysTemplate

If you need to support an earlier version you may want to consider this thread
