How to make this effect?

Can anyone please help me in understanding how this blog archive works? I think it is using an accordion style. I'm trying to achieve the effect where the previous year below goes down when the top is opened. How to do this? I have absolute positioning in mine.

change the "slide" in processing.js

I'm doing a science assignment that simulates the effects of different volcanoes. The user inputs information and then taking that information, there is a display of the effects the volcano has. when I try to switch the 'slide' from the input page to the output page using a 'next' button, it won't work.
here is the code: https://www.khanacademy.org/computer-programming/volcano-sim/6659613043589120
as you can see, the rectangle does pop up, but the rest of the stuff from the input page doesn't go away. Please help.
(also this is not exactly processing.js. it's on a site called khan academy that uses a very close spin-off of processing.js)
I made a spin-off of your program. The slides work now and I cleared out the long and confusing logic. It's different, but if you look through it a bit you should be able to pick up what it's doing.
Hope you find it helpful. :) If you have any trouble with any of it, just post in the Tips and Thanks there.

How to get iTunes volume control widget?

Anyone know of a way to get a volume control widget similar to iTunes?
Not sure how close you'll get but the tutorial below shows how to apply custom themes via images to a UISlider. I haven't tried it yet but I was looking at it the other day.

I found it when browsing the site below which is also a good resource when trying to find controls

RestKit and storing of data

I have a navigation controller where i have the list of appointments in a table view. I have an add button on the right side corner for the navigation controller. When the user clicks the add button a view will appear with the textfields and buttons. The problem is when ever the user (of the app) adds his appointments and clicks the add button it has to hit the server and store that data. I want to do that using RestKit. Can anybody tell me how to hit the server and how i can store the data.
Yes, Google can.
Here is the first result for the search 'restkit tutorial' :
http://mobile.tutsplus.com/tutorials/iphone/restkit_ios-sdk/
And, in case that one is a little out of date, here's the second result for the search 'restkit tutorial' :
http://mobile.tutsplus.com/tutorials/iphone/advanced-restkit-development_iphone-sdk/
The current documentation is only on github. Most other sources are outdated, thanks to RestKit's rapid development.
The wiki has a lot of good information, and you can find documentation that's always up-to-date in the docs directory.
I recently wrote a detailled overview of RestKit with many piece of code and I think it can help you to understand how it works and how to get things done.

Subclassing a UIAlertView

I'm desperately trying to find a way to make a custom UIAlertView that allows to display long texts and that would also allow to scroll the text as well. It seems to be possible since I've seen a few apps that do it (biteSms for instance) but I don't know how to do it.
Could someone help me please and tell me if any of you has managed to do it ?
Thanks for your help.
