I dont seem to understand the basic difference between factory method and abstract factory method.. Explanation with scenario of apple products

I went through few of previous question too about the difference between abstract factory and factory method. Suppose, I have apple factory, which produces 3 different apple products, iphone, ipod, and ipad. The specs of these 3 product are different as well.. but there may be some similarities though. which design pattern should be used.

any Help appreciated. Thankyou
