Say I have this JSON:

```
[
    {"x":"01", "ID":"1"},
    {"x":"02", "ID":"2"},
    {"x":"02", "ID":"3"},
    {"x":"03", "ID":"4"},
    {"x":"03", "ID":"5"},
    {"x":"03", "ID":"6"},
    {"x":"03", "ID":"7"}
]

```

and I want to create a UITableView like this:

```
------------
Section 01
------------
ID: 1
------------
Section 02
------------
ID: 2
ID: 3
------------
Section 03
------------
ID: 4
ID: 5
ID: 6
ID: 7

```

How can I find out how many sections I need and how do I output the correct data in each section?
