title: Is there any way to use "withRenderingMode(.alwaysTemplate)" with default image by not adding any tint colour of a button?
body: <p>I want to use "withRenderingMode(.alwaysTemplate)" to set an image on a button, but don't want to change any tint colour. Just want to set the default image.</p>
  
  <pre><code>let button = UIButton(type: .custom)
  let image = UIImage(named: "image_name")?.withRenderingMode(.alwaysTemplate)
  button.setImage(image, for: .normal)
  button.tintColor = UIColor.red
  </code></pre>
  
  <p>Here I didn't want to use red tint colour. But if though I didn't use any tint colour, I didn't get actual image. I just want to set actual image. </p>
