coding in objective-C

is it possible to code the arduino in objective-C

Only if you can find a objective-C compiler that outputs Atmel AVR code. I don't think such an animal exists.

the arduino variant of C++ is somewhat similar

yeah it was a shot in the dark ive been learning c++ and obj-c and ive came to perfer obj-c

I think, that for Arduino-class projects, that there is going to be a lot less difference between C++ and OC than you might be used to. It's more likely to look mostly like ordinary C with an occasional C++ism thrown in.
