iOS What to learn aside Obj C

Learn alot about what customers want, good interfaces, I wouldn't recommand learning designing yourself, rather find someone to do it..

You probably already know this, but ObjC is only the language used in iOS dev. The APIs are HUGE. I'd start digging into the APIs.

Graphics is also a big part of development, even for non-game apps. Might be worth looking into.

It depends what you want to do. If you need to interact with web sites, for example, you may need to learn about XML and JSON. On the other hand, you can generally interact with Facebook, Dropbox, etc. through an Objective-C interface.

Basically I'd stick to Objective-C for now and learn the rest when you need it. Learning XML will be pretty straightforward compared to learning Objective-C.

You should understand that this whole thing is an on going process. The lang ObjC has and will change over time (usually not that much, but it will change a bit) IE: the compiler has changed a few things concerning syntax.

The APIs, compiler, iOS... will continue to change. IE: Ref Counting is now automatic... These areas are something that you likely need to keep up on.

Once you know ObjC, I'd focus the effort on the APIs/OS that apply to what you want to do.

Example: you can spend a huge amount of time just on video stuff (filters, Aug Reality, etc...) so you really need to figure out which direction you want to go because there is a LOT to grab onto.

I use gimp quite a bit to do my design. I know my design is not the best but it gets me by and it was not too much of a time investment.

Learn C.

A lot of iOS APIs needed for the most advanced numerics, graphics and audio are based on plain C and C data types.

If the "venture" side is as important to you as the programming side, then spend a significant amount of time studying marketing strategy and techniques. Maybe half or more.

I agree with KarlJay. Objective C is not that complex a language. The Cocoa Touch frameworks, however, are very rich and complex, and take a while to get comfortable with.

I think they are too big for any one person to know everything about them, even. You need to learn the core frameworks, and learn how to use the documentation to find things as you need them.
