iphone - Animating TableView Instead of Plain Reloading -


i trying animate reloading of table view. currently, download array of table view items , if user reloads table view manually, downloads separate array, compares current newly downloaded, , if different, reloads table view newly downloaded array. there easy way to, somehow, compare arrays , insert/delete rows (animated, of course) accordingly?

i found apple's table view programming guide useful question:
