title: Paging UIScrollView with different page widths
body: <p>I would like to have a horizontal scrolling UIScrollView with paging enabled. The pages in this scrollview have different widths, so the scrolling distance differs from page to page.</p>
  
  <p>The goal is to make a picker for different points in time, e.g.:</p>
  
  <pre><code>|  Now  |  Yesterday evening |  Last Week  |  Last Month  |
      ^              ^                ^              ^           &lt;- stopps here
  </code></pre>
  
  <p>Here <code>|  Now  |</code> has a smaller width than <code>|  Yesterday evening  |</code>. When paging through this values, the scrollview should stop at the center of the according value.</p>
  
  <p>Is that possible?</p>
