title: Good resources for learning Objective-C
body: <p>I have developed for a number of years in Java, primarily for Linux and Windows.  During my undergrad and grad school times, I also did quite a bit in C and C++.  I have recently (in the last year and a half) started using primarily Apple computers at home, and am interested in exploring their Xcode development environment.  I am interested in learning how to use the Cocoa interface, etc.  However, I know nothing (or next to nothing) about Objective-C.  I am aware it is a pure superset of C, however I am interested in some resources for learning it.</p>
  
  <p>In the past, to teach myself concepts of Swing for Java, I have used O'Reilly books, such as the Swing Bible, Java Swing by Marc Loy et. al. Is there a similar book for Objective-C, or a book that is really good to learn from?  I would prefer if it was fairly technical, had examples, etc.  Has anyone else attempted to learn Objective-C this way?  Are there any specific things I should look at?</p>
  
  <p>Just to note, yes I do have K&amp;R, I have read it too many times to count, and I am aware of C syntax.  It has been a while, but I do remember large amounts of it.  :)  I did see <a href="https://stackoverflow.com/questions/535198/best-way-to-learn-objective-c">this question</a>, but I did not see any particular resources mentioned, simply some general statements about learning.</p>
  
  <p>Thanks!</p>
