Xcode Wish List:

Legacy Support

• Additional optional downloads:
  • Older SDKs, eg, for building ancient projects.
  • Older compilers (for same).
• Either ship gcc/llvm-gcc or don't. Don't ship clang and call it 'gcc', that just breaks anyone who actually needs GCC and finds your not-gcc in the PATH.

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

CGRectDivide is handy for slicing up a rectangle.

Example of getting a slice and the remaining area of a rectange.

CGRect rect = CGRectMake(0, 0, 240, 150);
  
CGRect remainder, slice;
    
CGRectDivide(rect, &slice, &remainder, 120, CGRectMinYEdge);

How the get the 512x512 icon for an app.

Look for this app on the itunes.apple.com website (Google is your friend)

For example, this excellent app.

http://itunes.apple.com/au/app/bancomap/id309009025?mt=8

Look for the URL of the icon in the page (it's a 175x175 picture).
I use Safari, so right click on the icon and choose "Inspect Element"
