iOS SDK and SQLite: Building Data-Driven Apps

with Bill Weinman

Video: Welcome

Hi, I'm Bill Weinman, and welcome to iOS SDK and SQLite Building Data-Driven Applications. In this course I will show you how to build a solid RSS reader for iOS that supports both the iPhone and iPad form factors, integrating XML data into a clean and simple presentation. I'll explain how to use the SQL database, which is included in iOS, and display information in a clear, intuitive table view. I'll teach you how to code the necessary view controllers for your application and how to use the Settings application to provide a Preferences Interface for your users.

iOS SDK and SQLite: Building Data-Driven Apps
3h 45m Intermediate Jan 16, 2013

Viewers: in countries Watching now:

The iOS software development kit (SDK) includes the popular SQLite library, a lightweight yet powerful relational database engine that is easily embedded into an application. In this course, Bill Weinman teaches you how to build an RSS reader for iOS devices, integrating XML data and a streamlined interface. He explains how to use the SQLite database, display information in a table view, code view controllers, and create a preferences pane for your app. The resulting application is optimized for all iPhone and iPad displays.

Topics include:
  • Prototyping the app
  • Coding and working with a testbed
  • Creating an Objective-C interface for SQLite
  • Designing a database schema
  • Creating the view controllers
  • Reading and writing to the database
  • Parsing the RSS feed with NSXMLParser
  • Updating the item view with feed items
  • Implementing the pull to refresh gesture for iOS 6
  • Creating a universal application with multiple views

Q: Why is the RSSDB library in the exercise files different than the one in the videos?

A: The RSSDB library had to be updated to work around a bug in the iOS 7 SDK.

There is a bug in the iOS 7 SDK that prevents the BWDB fast enumeration implementation from working on a device. The symptom is code that runs fine on the emulator, but not on a device. iOS devices use an ARM processor, while the emulator runs on your Mac's Intel processor. This points to the LLVM ARM code generator as the source of the bug. Because the bug appears to be in the LLVM compiler, it may be some time before it is fixed.

As a workaround we have changed the getFeedIDs and getItemIDs methods in the RSSDB library so they don't use Objective C fast enumeration. 

Please note that this same bug also affects some of the BWDB testbed code in Chapter 2. The result is that it will run on the emulator but not on a device.

Q: After upgrading to Xcode 5.1 I get an error that says:

"Used type va_list (aka_builtin_va_list) where arithmetic or pointer type is required"

A: Please download the exercise files again to get the latest version of the BWDB library.
