title: Creating an animated gradient background similar to the Solar Weather Application in xCode
body: <p>Even though I have asked this question before, I would like to reach out again to clarify what I would like to accomplish with your help. I was wondering how you would create a background of and iOS application in xCode similar to the background of the Solar weather app (screenshots provided) that changes slightly over time (in a cycle). As you can see the gradient is very smooth and obviously contains more than two main points.
  Any help with example or snippets of code would be greatly appreciated. Thanks Again, Ben.</p>
