Greetings, NSHipsters!

As we prepare to increment our NSDateComponents -year by 1, it's time once again for NSHipster end-of-the-year Reader Submissions! Last year, we got some mind-blowing tips and tricks. With the release of iOS 7 & Mavericks, and a year's worth of new developments in the Objective-C ecosystem, there should be a ton of new stuff to write up for this year.

Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Here are a few examples of the kind of things I'd like to see:

  • Using NSStringFromSelector(@selector()) as a safer way to do KVC / KVO / NSCoding.
  • Panic's [rather surprising discovery about the internals of the Lightning Digital AV Adapter](http://www.panic.com/blog/the-lightning-di

Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
