title: UIWebview caching to disk
body: <p>I have a simple iOS app that loads and list of links and presents them in a UIWebview. The app, when installed, is ~2MB. After clicking around through some of the links, I noticed that the disk usage of documents and data jumped to over 10MB. As a couple days went on, I noticed the disk usage continued to grow. My question is, what is the best way to manage disk storage on iOS?</p>
  
  <p>The goal of this app is to be very minimal and not heavy on resources, but I'm concerned that it will continue to consume more and more disk space with, what I assume is, cached web content. Should I / is there a way to set a cache size? Or does iOS just handle this for me and delete old data eventually?</p>
