I need a class to manage URL classification data structures on iOS (you don't need to do the actual classification, just create the data management, the data will come from files/function calls)

## Deliverables
I need a class to manage URL classification data structures on iOS (you don't need to do the actual
classification, just create the data management, the data will come from files/function calls)
Stage 1:
Defining the categories, there will be an enum in the class with all the possible categories (I will change
it later to all my categories), here is a sample list (taken from my C program):
typedef enum _CategoriesEnum
{
ceAbortion=1,
ceAds,
ceAdult, //Not porn, but still not child save
ceViolence,
ceNude,
ceAstrology,
ceBanking,
ceAlcoholDrugs
} CategoriesEnum
Stage 2:
Loading data from files, the data structure is directories under the main directory, each directory has a
file called domains which contains the domains for that category, when I load the file I will specify the
master directory and a list of conversion between the directory name and enum.
Directory structure sample:
Main dir:
--ads
----domains (file)
--adult
----domains (file)
The lookup will be:
ads -> ceAds
adult -> ceAdult
The data in the structure is a domain name, so for example: [url removed, login to view], [url removed, login to view], [url removed, login to view]
The data should be stored in a data container that has a fast search capabilities like a tree or map
There can be more then one category for a site.
Stage 3:
Looking up the data, I need a function that I will provide a URL to it, the function will extract the host
from the url, for example: <[url removed, login to view]>, the function will only search [[url removed, login to view]][1]
The way the function will search the data is by doing searches for all possible host name, for example:
[[url removed, login to view]][1] will also be searched for [url removed, login to view] if the [[url removed, login to view]][1] was not found.
If the category is found, I will get back the enum of the category or categories.
Stage 4:
Adding a URL, I will be able to add a URL using a call, for example:
AddURL("[url removed, login to view]",ceBanking)
I can also specify:
AddURL("[url removed, login to view]",ceAds)
and [url removed, login to view] will have more then one category.
Stage 5:
When creating the class, I will be able to decide at creation if I want the class to have locking for thread
safe, or not. The thread safety only needs to be for adding/querying the data via the API, at the stage of
loading the data, there's no need for safety.
Stage 6:
Provide a test app that will load the data from file (data will be provided by me), and give me a two text
boxes, one to query categories, I will enter a url and it will write the category, the second text box will
allow me to add a url and a category.
