[Video tutorial] aggregating data IOS project development combat: Barcode Finder

Course Background:

Aggregated data is one of the largest basic data API providers in the country. Free to provide safe, stable and efficient data from weather inquiries, air quality, map coordinates to financial funds, e-commerce parity, illegal inquiries and other fields. Developers can use the aggregation data API for the rapid development of mobile apps, eliminating data collection, maintenance and so on, greatly reducing the development cycle and cost.

Core content:

1. Barcode Finder structure analysis.
2. How to add the aggregation data SDK to the project.
3. Encapsulation of models and business classes.
4. Data transfer between controllers.
5.tableView and the use of WebView.

Development Environment: Xcode 6, Mac OS X 10.10

This class through the analysis of bar code query UI structure and business logic, quickly build up the Barcode Finder business interface.

2. Introduction to Aggregation Data SDK usage

This lesson introduces the download of the Aggregation Data SDK, as well as the use of the SDK with the documentation and the Demo, to add the framework for the project and to obtain the OpenID and request parameters for the project by applying for aggregated data accounts. and analyze the return data of aggregated data by testing the code.

3. Perfect City Selection interface

This lesson demonstrates how to add third-party frameworks and business classes and models packaged by geek College teachers to the project and quickly use them, and display the captured data in the city selection interface, and enable data transfer between the city selection interface and the home page.

4. Details of the product interface to complete the preliminary

This class analyzes the product details interface data, demonstrates how to use the already packaged business classes and models to display e-commerce and supermarket data to the interface, and give the aggregate data to obtain data type uncertainty solution.

5. Product Details interface Complete data display

This lesson demonstrates how to add a group header control and how to use Xib to quickly create a tableView Headerview, and pass the server data utilization model to a control within Xib, where ImageView's picture shows Sdwebimage.

6. Perfect Purchase Interface

This lesson shows how to change the view of the controller in Uiviewcontroller to WebView and use WebView to display the purchase interface and use Mbprogresshud to give a UI hint when the e-commerce does not have a link to purchase.
