If you are looking to extend your iOS programming skills beyond the
basics then More iPhone Development with Objective-C is for you.
Authors Dave Mark, Jayant Varma, Jeff LaMarche, Alex
Horovitz, and Kevin Kim explain concepts as only they can--with
code snippets you can customize and use, as you like, in your own apps.
More iPhone Development with Objective-C is an independent companion
to Beginning iPhone Development with Objective-C. That is, it is a
perfect second book, but it is also a great book for those looking to
improve their skills who have already programmed for iOS. In particular
it includes a series of chapters devoted to Core Data, the standard for
Apple persistence. The authors carefully step through each Core Data
concept and show techniques and tips specifically for writing larger
apps--offering a breadth of coverage you won't find anywhere else.
More iPhone Development with Objective-C covers a variety of other
topics, including Multipeer Connectivity's relatively simple
Bluetooth/WiFi peer-to-peer model, MapKit, and media library access and
playback so that your applications can utilize media on your users'
computer. You'll also find coverage of Interface Builder, Live Previews
and Custom Controls and some advanced techniques for debugging your
applications. The book is filled with useful topics that will bring your
programs up-to-date with the new functionality built into iOS.
