Well, I've started with iPod/iPhone programming using Head First iPhone Development (O'reilly) and I'm typing code out of the book. There are two problems, one is programming related and the other is not.

I don't understand the format of objective-c methods. I'm getting an few errors now, based on source code from the book. Which leads me to my next issue.
Some of the code is buggy. I think so because I couldn't get the code to run without modifying it. The book has some typos in the text since it's a first edition and whatnot, but could my "fixing" the code have to do with it?

So... Where can I learn more about objective-c methods and how they work in terms of structure and where the return type and arguments go?

For those with the book, I'm in the middle of the InstaTweet app towards the beginning.

Thanks.
