title: Custom UIView for HTML element in UIWebView
body: <p>I would like to add a custom view to the layout of an UIWebView, so that the HTML/JS/CSS describe the layout of the "page" with my custom controls in it. Ideally, it would be possible to place e.g. a special  element that triggers a callback into my code that would allow me to place my own UIView derivative on the specified coordinates (and it would of course scroll and zoom with the parent UIWebView) and with the specified set of parameters.</p>
  
  <p>A poor man's choice would be something similar to this question:
  <a href="https://stackoverflow.com/questions/3360139/getting-the-position-of-an-html-element-in-uiwebview">Getting the position of an HTML element in UIWebView</a> however I am not sure how reliable that would be w.r.t layout changes.</p>
