问题 I am trying to create a UITableView where more rows loads automatically as I scroll to the bottom of the list. This is typically like the search function on the Amazon app for iPhone.

问题 First time I view the page with an animated .gif it plays fine on page load (lasts about 2 secs). On refresh (F5), the .gif no longer plays and only the last frame of gif animation is shown.
