How to group tableview cells based on field in JSON array

Question

Essentially I have am using JSON data to create an array and form a tableview.

I would like the table cells to be grouped by one of the fields from the JSON array.

You can achieve this by making an array of array. So something like this

[[{"customer": "customer1", "number": "123"}, {"customer": "customer1", "number": "456"}], [{"customer": "customer2", "number": "678"}, {"customer": "customer2", "number": "890"}]]

This is not the only data structure you can use to group. Another possibility is:

{"customer1": [{"customer": "customer1", "number": "123"}, {"customer": "customer1", "number": "456"}], "customer2": [{"customer": "customer2", "number": "678"}, {"customer": "customer2", "number": "890"}]}

Then you can use UITableView sections to group by customers. Section count would be the number of inside arrays and each section would contain as many rows as there are numbers in that inside array.
