How to addapt iphone background?

问题:

I am new to developing and I am trying to find how to have a different background image for different iphones (4s 5 5s ect...) I did manage to have a background image but its the same in all simulators so it only fits the Iphone 6 plus any ideas on how I could do this?

thank you
