Conditional compile when running in Simulator as opposed to on a device

Question

Is there a compiler directive I can use to compile a different line of code when targetting the simulator as opposed to my device. Something like:

# IF SIMULATOR         


        

Answer 1

Update: (Deprecated/Obsolete) This only worked for a few years, and does not work any more. (10+ years later)

For the record, here's another method which Apple uses in some of their official Sample Code:

#if TARGET_CPU_ARM
  // Only executes on an iPhone or iPod touch device
  [self.imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera];
#else
  // Only executes on the Simulator
  [self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
#endif
