Answer 1

you can render image layer with text

like this // imageWithLabel handle final image

txtLabel.backgroundColor = UIColor.clearColor()
txtLabel.textAlignment = .Center
txtLabel.textColor = UIColor.whiteColor()
txtLabel.text = text

UIGraphicsBeginImageContextWithOptions(txtLabel.bounds.size, false, 0);
imgImage.layer.renderInContext(UIGraphicsGetCurrentContext()!)
label.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let imageWithLabel = UIGraphicsGetImageFromCurrentImageContext() // here is final image
UIGraphicsEndImageContext();
