title: Programmatically get path to Application Support folder
body: <p>I'm trying to get an NSString for the user's Application Support folder.</p>
  
  <p>I know I can do <code>NSString *path = @"~/Library/Application Support";</code> but this doesn't seem very elegant. I've played around with using <code>NSSearchPathForDirectoriesInDomains</code> but it seems to be quite long-winded and creates several unnecessary objects (at least, my implementation of it does).</p>
  
  <p>Is there a simple way to do this?</p>
