Getting numbers from CFDictionary for use in calculations, iPhone

Question

I found this on my travels:

How do I get the values (as a number):

#define kIOPSMaxCapacityKey "Max Capacity"

and

#define kIOPSDesignCapacityKey "DesignCapacity"

I want to use them throughout the application. What do I need to add to my project and how to extract numbers?

Many thanks,

Stewart

Once you find out where the real dictionary is, it stores these values, you can access the value from the dictionary using the following call:

CFDictionaryGetValue (
   CFDictionaryRef theDict,
   const void *key
);
