Arabic keyboard? IPhone/text?

Does anybody know a keyboard that shows the English and the Arabic on?
I don't know how to explain this but lets say I want to text "What are you doing?" to someone in Arabic. I want to know how each letter in Arabic looks like and where it is on the keyboard. If you know what I mean? I want to text on the Arabic keyboard on my iPhone. But I don't know where A B C D and so on are on the keyboard.
Do you know any sites/links that show which letter is what? Like ABCDEF in Arabic isn't in the same place as the English keyboard is it? Do you know any that show where to click and where each letter is? Sorry if I've confused you.

Get the swiftkey app, and download the arabic language.

I have that on my samsung galaxy s4, its really good. Especially the latest updates.

Try downloading Ibrahim arabic keyboard. It has both the arabic and the English letters. After downloading, go to the settings keyboard and choose add a new keyboard--> IBrahim arabic keyboard.

Go to setting---->General--->Keyboard--->Keybo… Keyboard and select Arabic
After that whenever you try to type, there should be like a button that shows a sphere, click on it until you get the Arabic letters.
---
You will still have your English keyboard, just click on the same button that shows a sphere again
---
You can also use yamli.com, you can write Arabic using latin letter and they will transform it to normal arabic

My keyboard is both arabic english… And no the letters are not the same… For example the letter k is with the letter "ن"…ن=n

so you can't write your message depends on the places of letters

hope that someone would give you more information
