GSOoC 2012 Week 10 report

This week, the primary focus has been to complete the store-wise price calculation related features.

A subtotal display is added to the ListContentTableViewController. Store filter is also implemented and added to the application.

Functionality of both feature are similar to the android version.

The subtotal calculation sums the product of unit price and quantity of all unchecked items. And updates the sum when the user load the list, modifies the list or check/ uncheck the items.

The Store filter enables user to display items with price information available within a certain store. The app would load all the stores that are related to the displayed list. After one is selected by the user, those items that has price information related to the selected store would be displayed, others would be hided.

Screen shots of both feature have been attached below.

 

These two screen shot shows the button to filter and the action sheet popping up after clicking filter button.

After completing the store-wise price calculation, I feel that the feature could be improve as below:

Now, list owns stores. In other words, when we create a new list, we have to input the price information from scratch. Which can be a thing that users do not want. If we could change it around, and makes Item owns the stores. That could be potentially better. For example, I buy potato chips on Wednesday and recorded down it is $3.00. If I add potato chips to the Friday shopping list, it would be good to have the $3.00 information in the list automatically, then “forget” about it and ask users for it again.

Of course, this would add complexity to the algorithms. Other potential problem could be that a long list of prices and stores might be associated with a item, and the database might be messy and difficult to clean up.

I could now, focus on cloud synchronization solely. Hope it could be done soon!
