Write an iPhone App features - Chart/Graph

General Requirements:

We have existing iPhone application and would like engage freelancer, team or companies to work on a few small projects/features.

You must be able to communicate with English and know Objective-C. Have to be able to communicate in Skype at least once a day for the whole durations of this project between 1200 - 2100hrs (GMT + 8:00).

Project Requirements:

We have existing Web Services that returns JSON data. We need you to populate the graph and chart interactively with two separate JSON Data.

First feature - Line Graph:

Months: January to December, Plot two lines ( Example: Sales and Expenses ) with different colour. Sales and Expenses will be in numbers. We will also provide the months inside the JSON data. We will give you the JSON Data. Only in Portrait view.

Second feature - Pie Chart:

Create the Pie Chart with four items ( Example: Apple, Orange, Durian, Pear ) with different colour with percentage based on the quantity of the fruits.

Below the pie chart should display four buttons that when user tap/action will remove or add back. The Four buttons will be name ( Example: Apple 20, Orange 5, Durian 30, Pear 50 ). We will give you the JSON Data. Only in Portrait view.

Technical requirements:

We need it to work on iPhone, iOS7 and above. It must be written in Objective-C. You have to deliver both Line Graph and Pie Chart in two separate iOS Project. IOS Project has to use Storyboarding with their ViewController and NOT .xib. Regarding the iOS custom library, We would love the Pie Chart to be MagicPie. You can recommend the Line Graph, Pie Chart iOS Library you are using or anything that you did before. We will evaluate whether it is good. Both features have to happen on ViewDidLoad with proper methods created to consume JSON Data. You do not need to do any NSURLConnection/NSURLRequest, you will just plot the graphs/piechart with two sets of Sample JSON data. You have to also provide us details and guide us on how to integrate into our existing storyboard.

If you are good and fast, after this project we will engage you for another two iPhone projects/features.

Have to complete 3 - 5 days MAX.
