How do I set up my editor to "ipadview"

I just started my first unity project after having used game salad for about half a year, figured it was about time. **Problem:** In game salad the editor is set up so that you can see the edge of the device your developing for. In unity I can't wrap my head around how to make the camera/editor to show the entire iPad screen at once. When I'm editing in the editor i have no idea of where the elements will appear on the iPad screen Thanks.
