B6.0 - 21 December 2009

The book’s final chapter is included in this beta, along with two appendices: one is on installing Xcode, the other is on writing software for the iPhone.

All three of these are fairly recent and should be treated as drafts. The references made to other books and online sources are not yet correctly formatted, and some of the links given in footnotes don’t work correctly if clicked from the pdf. These issues will obviously be fixed for the next release.

Chapter 8 has been updated with some editorial changes, Xcode 3.2 differences, and refreshed images. Chapter 9 has some alterations, code inconsistencies corrected, and a new section of text about the perils of using uninitialized object pointers in conditional statements. Chapter 10 has a few minor changes. All three of these chapters now have code available from the book’s website.
