I know there is a couple of differences between the PC unity engine and the IOS . But is most of it the same ? If i get the book of unity and essentials will that be enough to give me an idea about the scripting and other stuff in Unity and Unity IOS ? I've searched the site and read a few but I would like a quick answer with no links please :)
Yes Unity Essentials is a pretty good book to start, I have a friend that created a game for IOS and he told me that book helped him a lot, Ive read the book and I have an ios game finished too, so yes but.. The game focuses mainly on PC games so you will need to research to get a little more info on ios functions.
Here is another book that just focusses on IOS:
Good Luck Jabor.
Design3 also has material on iOS in Unity:
