问题
My Problem is this, I want to add some component to my App I saw in some other App. Everytime I wnat to do this, I start googling around for the name. It took me some time to find the name of UIActionSheet. Now I'm looking for that transparent overlay that appears when you turn the volume up and down.
So, is there a good visual guide to the UIKit components? As an example, see the visual guide to swing components or this visual guide which is way to short/incomplete. And secondly, what's the name of the component I'm looking for?
回答1:
The iOS documentation has a section called iOS UIKit UI Catalog that shows the various UI features by name with links to the API docs and recommend how and when they should be used.
回答2:
Apple has provided a sample iPhone application called UICatalog. It lists all (or most?) of the standard UIKit component in different variants.
You can download the sample from here.

i recently had the same problem. Googling a lot i came across the following page. This overlay works pretty well and is easy to use.
look at: http://github.com/jdg/MBProgressHUD
Hope this is what you were looking for.
