title: How can I change image tintColor
body: <p>I'm receiving image from a server, then based on a color chosen by the user, the image color will be changed.</p>
  
  <p>I tried the following :</p>
  
  <pre><code>_sketchImageView.image = [_sketchImageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
  [_sketchImageView setTintColor:color];
  </code></pre>
  
  <p>i got the opposite of my goal (the white color outside UIImage is colored with the chosen color). </p>
  
  <p>what is going wrong?</p>
  
  <p>i need to do the same in this question,the provided solution doesn't solve my case.
