Saving data using NSDictionaries

Okay, I had a blog viewer inquire about this problem. They were wanting to save information about people in a single XML file but didn't know how to do it. 

If you want to save information about people, the easiest way to do that is by using nested dictionaries where a single root dictionary contains dictionaries with your data. 

When you store all your dictionaries in a root dictionary, you can just write the root dictionary to file and and you will get an XML file representation of you data. 

I have a demonstration app up on the server, you just can't find it from the first page. 

Here is the link to the dictionary example to demonstrate how you do this.
Make sure you build it in XCode first before you run it. The current built file doesn't reflect a change I made in code to keep it from locking up your computer. 

I hope this helps!
Happy coding! :-)
