UIButton with GradientLayer obscures image and darkens gradient
So I managed to get around this by doing a [button bringSubviewToFront:button.imageView] after adding the gradient. Seems that no matter what I do the new layer will add on top of the imageView, so I need to push that to the front afterwards.
Objective-C:
[button bringSubviewToFront:button.imageView] Swift 4.1:
button.bringSubview(toFront:button.imageView!)
Alternatively, you can insert the gradient layer below the image view's layer
CAGradientLayer* gradient = [CAGradientLayer layer];// ...[button.layer insertSublayer:gradient below:button.imageView.layer];
SWIFT 3
Here goes an example: (Based on Neil answer)
let layer = CAGradientLayer() layer.frame = CGRect(x: 0, y: 0, width: myButtonOutlet.layer.frame.size.width, height: myButtonOutlet..layer.frame.size.height) layer.colors = [UIColor.white.cgColor, pixelColorReceta.cgColor] layer.masksToBounds = true layer.cornerRadius = myButtonOutlet.layer.cornerRadius myButtonOutlet.layer.insertSublayer(layer, below: myButtonOutlet..imageView?.layer)Happy coding :)
