I have a TableView in a View, and when it scrolls, the rounded part of the table at the bottom is cut off. I’d like it to behave like the Stocks app, where the table view is fixed with round corners and scrolling scrolls within the fixed rounded corners. How is that done?

First, add the QuartzCore framework library to your project if you haven’t.
Then, in your UIViewController that manages the UITableView, do:
And then on viewDidLoad:
And that will give it 8px rounded corners. The QuartzCore framework exposes a lot of very useful things that you can do with UIViews and their internal layers. Experiment away!
