Programming/Coding iPhone Apps vol.. learning

[tn123]

Hey there any fellow nters can point someone out in the direction of where to learn how to make/code iPhone apps... I'm trying to pic up a new skill and I think this would be beneficial...

I checked out codeacademy but those are paid classes and cost 14k.. Anywhere to learn by yourself for free or for less than that much. 

Any help would be greatly appreciated, as always.
