How to show tint colored image in CALayer on iOS?

Question

I need to show a tint colored image in CALayer.

It works for UIImageView:

imageView.image = image.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)

But CALayer shows the image with its original color and not the tint color.

let tintedImage = image.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
layer.contents = tintedImage.CGImage

Is there a way to show tinted image in CALayer as well?

Answer 1

I think my solution is far less cumbersome:

let maskLayer = CALayer()
maskLayer.frame = layer.bounds
maskLayer.contents = tintedImage.CGImage
layer.mask = maskLayer
layer.backgroundColor = UIColor.redColor().CGColor

let me know if it works fine:)
