Programming in Objective-C Programming in Objective-C
Programming in Objective-C is a concise, carefully written tutorial on the basics of Objective-C and object-oriented programming. The book makes no assumption about prior experience with object-oriented programming languages or with the C language (upon which Objective-C is based). And because of this, both novice and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C.

Detect already loaded older version of a preference pane

Published in: Objective C 

This detects if a preference pane is loaded over an already loaded older version. If the version mismatches, the reload tool (http://snipplr.com/view/3924/reload-a-preference-pane/) is launched and System Preferences is quitted.
