title: iOS and OSX build in one Xcode project
body: <p>I had a question regarding IOS projects and OSX projects on Xcode. Essentially I have a section of code that works under OSX base sdk (its mainly a OSIRIX plug in) and will only work by having an OSX base SDK. The OSX base sdk code just lets me choose images, I also have a section of code that will allow me to process the data from the images, this functions only under an iOS base SDK. Is there way to have two sections of code that function under different base sdk functioning under one .m file?</p>
  
  <p>Please let me know if I am too vague, I am currently very confused on what to do about it.</p>
