How to do smooth scrolling in UIScrollView?

Question

I am using Apple's page control sample and showing three different types of views.

The scrolling is very slow on the device because I am using a UITableView and 5-7 labels on my view. Everything is updating from a database. How do I increase the performance of my scrolling behavior?

Answer 1

使用UITableView在Tweetie中快速滚动

Answer 2

Or you could make sure all components on your UITableViewCells are opaque. UITableView doesn't handle well transparency when scrolling.

Answer 3

As Nick noted, the link back to the original Tweetie article, but I found it in the Wayback Machine - here

In researching this issue for myself, I found two other articles that were useful:
