NSHipster Quiz #4

The fourth and final NSHipster pub quiz of the year was held in the beautiful city of Amsterdam on October 22nd, with help from the good folks at Appsterdam, The Big Nerd Ranch, and Heroku.

The competition was fierce, but ultimately the team of Mike Lee, Judy Chen, Eloy Dúran, Alexander Repty, Maxie Ketschau-Repty, and Sernin van de Krol were victorious. This was, by design, to be the highest-scoring of any pub quiz, with generous portions of extra points, and Team “Graceful Hoppers” came through with an impressive 53 points (which, interestingly enough, only edged out the 2nd place team by ½ of a point).

As always, you can play along at home or at work with your colleagues. Here are the rules:

  • There are 4 Rounds, with 10 questions each
  • Record answers on a separate sheet of paper
  • Each correct answer to a question gets you 1 point (unless otherwise specified)
  • Play with up to 5 friends for maximum enjoyment
  • Don’t be lame and look things up on the Internet or in Xcode

Round 1: General Knowledge

Current events, miscellaneous tidbits, and random trivia. Following a time-honored traditions for NSHipster quizzes, the first round is always a mis-mash of people, places, and pop culture.

  2. What two products were announced during the last event to be held at the Yerba Buena Center for the Arts, on March 7, 2012? (1pt for each correct answer)
  3. Which company’s CEO was recently named as Apple’s new Head of Retail? (1pt bonus if you know her name)
  4. In September of this year, Steve Ballmer held his last meeting as CEO at Microsoft. How many years did he serve in this role?

Round 2: Foundation Potpourri

With the fluff out of the way, it’s now time to dive into some hardcore Cocoa fundamentals. How well do you know the standard library?

  9. Name the 4 Classes that conform to <NSLocking> (1 pt. each)
  10. What is the name of the method called by the following code:
array[1] = @"foo";

Round 3: Picture Round - Indie Devs

Following another tradition of the NSHipster quiz is everybody’s favorite: the Picture Round! This time, the theme is indie developers. Earn up to 3 points for each set of pictures by naming the founder, the name of the company they’re known for, and the name of their flagship app represented by the icon.

Round 4: NSAnagram

And finally, an admittedly sadistic round that combines wordplay with Cocoa arcana. Each question is an anagram, whose letters can be rearranged to form the name of a class or type in a well-known system framework (hint: Foundation, Core Foundation, UIKit, and AddressBook are represented here).
