Kris: fair enough, his link to 9to5Mac is written as “Apple is set to switch the back-end data in iOS’s Maps app from Google to its own mapping services”. But if I am inferring that they’d bring the SDK along for the ride, I don’t think that’s a big leap to make; it’s in their best interest to get third-party apps off the Google dependency too.

I think Gruber was referring to the Maps application, rather than the Map Kit SDK. The Maps app does provide driving, walking, and public transportation directions.

Congratulations on getting the book out. I ordered it the instant I found out about it back in August. I’m really looking forward to working through it.

How about a book on Core Video and AVFoundation. I’m a very experienced programmer and have spent the last three years writing iOS apps. I just recently had to do some video. Yikes! Talk about opaque and difficult to use. Luckily the requirements were simple enough that I could get through by stealing hunks of code from Apple’s sample code. I’m not sure I could explain the code to anyone, but it works which is fine with me. Maybe your book would help even though it’s about audio?

ignatz: The pain point is going to be C and the programming customs that go with it. We cover it in an appendix to iOS SDK Development, but that’s just a taste. Re-read that and then see how you handle the first chapter of Learning Core Audio and its first code example… I expect the hard part will be the manual memory management, pointer trickery, and the non-OO nature of C libraries (structs and functions rather than classes and methods).

That said, there are “old C dude” practices that we rely on without apology that you’ll just have to get used to: using 0/NULL/nil in if statements, bit-fields for flags (this is a big thing in the AudioStreamBasicDescription), function pointers and callbacks to them, etc.
