title: Abstracting out Strings in objective-c (iPhone)
body: <p>I am working on an iphone application and I am wondering what the correct practice is for abstracting out strings. I am used to creating a file with constant strings and referencing them in my application (such as urls, port numbers or even button labels). I am wondering if this is considered good practice in Obj-C and if so what the best way to do it is? Should I make a class with the strings? Or use the ".strings" file? </p>
  
  <p>p.s I may be localizing my application at a later time. I havent looked into how to do it, but I figure abstracting out my strings is a good idea while i'm developping.</p>
  
  <p>Thank you!
