UITableview Data - iphone

Question

I am making an application in which I have to read the contacts from an ABAddressBook.
I have read the data and stored it in a dictionary.I want to display the names
alphabetically in every section. Each object in the dictionary refers to the details of a single person. Any help ?
(
{
letter = D;
name = zzzz;
telephone = "1234566";
},
{
letter = R;
name = "ffff";
telephone = "332333";
},
{
letter = A;
name = aaaaa;
telephone = "1112226";
},
{
letter = s;
name = ssssss;
telephone = "234 56792";
},
{
letter = K;
name = "Klll";
telephone = "[phone]";
}
)
