Seo Master present to you: By Ashleigh Rentz, Google Developers Blog Editor Emerita

It’s been two months since we wrapped up Google I/O 2012, and there’s been no shortage of topics for Google’s developer advocates to discuss with the community afterward! Google Developers Live opens the door to two-way communication all year long by hosting online office hours sessions, but it also offers other viewing opportunities like interviews with community figures and tech-centric reviews of Android games. With over 100 new episodes recorded for posterity since I/O, chances are good that we’ve all missed something fascinating. Why not flip backward through the events calendar this weekend and see what’s been happening in our studios?

While our own cameras are focused on earthly developers, NASA has their sights on the skies. This week, astronomers discovered a new binary star system with multiple planets circling those stars. One of these planets with two suns is even within the habitable zone. It may not be in a galaxy far far away, but the similarities to Tatooine are still fun to speculate on.

Finally, this week’s addition of bicycle navigation to Google Maps for Android is welcome news to we pedal-powered commuters, but the stakes have been raised... A team at University of Maryland recently built a new human-powered helicopter, and videos of the test flights are now making the rounds on YouTube. It’ll be an awesome day when Google Maps helps me find my way to work pedaling one of those!

Each week, we bring you a Fridaygram full of interesting things that help keep your weekend geekarific. Ashleigh is our editor emerita who comes back to visit when Scott takes some time away from the office. This week, we join many others around the world in saying a somber farewell to Neil Armstrong, an inspiration to us all.

Four years ago, we introduced an Objective-C library for Google Data APIs. At first, it supported a scant three services - Google Base, Calendar, and Spreadsheets. Perhaps more surprising is that it was written just for Mac applications; the iPhone SDK was still a year off. In the years since, the library has grown to support 16 APIs, and has been used in many hundreds of applications. In a fine example of unforeseen consequences, most of those applications run not on the Mac but on iOS.

The Google Data APIs were built on XML and the Atom Publishing Protocol, a reasonable industry standard for the time. But mobile, low-power, and bandwidth-limited computers are now the biggest audience for client software. Across the Internet, XML and AtomPub have given way to the lighter-weight JSON data interchange format.

Other fundamental changes have also shifted the API landscape. Password-based authentication is being supplanted by the more secure and flexible OAuth 2 standard. The number of APIs has grown dramatically, making it impractical to hand-craft data classes for all APIs and all languages. When services offer API improvements, developers want access to those changes as quickly as possible.

To support this evolving world, we are introducing a brand new library for Cocoa developers, the Google APIs Client Library for Objective-C. The library supports recent Google JSON APIs, including Tasks, Latitude, Books, URL Shortener, and many others. It is designed to make efficient use of the device’s processor and memory, so it’s a great fit for iOS applications.

The new library includes high-level Objective-C interfaces and data classes for each service, generated from the Google APIs Discovery Service. This lets the library model data not just as generic JSON dictionaries, but also with first-class Objective-C 2.0 objects. The classes include properties for each field, letting developers take advantage of Xcode’s code completion and syntax and type checking.

Here’s how easy it is to use the library and the new Google Books API to search for and print the titles of free ebooks by Samuel Clemens:

#import "GTLBooks.h"

GTLServiceBooks *service = [[GTLServiceBooks alloc] init];

GTLQueryBooks *query = 
  [GTLQueryBooks queryForVolumesListWithQ:@"Mark Twain"];
query.filter = kGTLBooksFilterFreeEbooks;

[service executeQuery:query
    completionHandler:^(GTLServiceTicket *ticket,
                        id object, NSError *error) {
      // callback
      if (error == nil) {
        GTLBooksVolumes *results = object;
        for (GTLBooksVolume *volume in results) {
          NSLog(@"%@", volume.volumeInfo.title);
        }
      }
    }];

The library supports Google’s partial response and partial update protocols, so even items of data-rich APIs can be retrieved and updated with minimal network overhead. It also offers a simple, efficient batch model, so many queries can be combined into one http request and response, speeding up applications.

When we introduced the previous Objective-C library, it was with this assertion: When you trust your personal data to Google, it's still your data. You're free to edit it, to share it with others, or to download it and take it somewhere else entirely. We hope the new library and Google’s growing collection of APIs help iOS and Mac developers to keep that principle meaningful for many years to come. You can start using the Google APIs Client Library for Objective-C by checking it out from our open-source project site and by subscribing to the discussion group.

Since Google I/O 2010, we've been developing APIs that can provide descriptions of themselves via metadata. This new technique makes it easier to create and maintain client libraries that support more languages, work with more APIs, and are easier to use than ever before. This post announces one of several recent major milestones for our client libraries.
