NSHipster Quiz #3

Written by Mattt Thompson on

NSHipster Pub Quiz came to New York City on July 30th. Like our first and second quizzes, questions ranged from random Apple trivia to obscure framework questions—this time, with a particular focus on hardware rumors and questions about iOS [REDACTED].

The event was hosted by Meetup, and sponsored by Heroku. Dozens of the best and brightest minds in Objective-C attended the event, with the team "The Forstall Five" (@mb, @bcapps, @ethicalpaul, @grantjbutler, and @conbrolution) taking first place.

If you'd like to play along at home, or test your team's mettle at work, here are some guidelines:

  • 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
