programing Objective-C 3rd Edition vs 4th Edition

[iosdev]

folks,

i am new to this forum and I have a silly question.   
 
I have started learning objective-C with 3rd edition. I see there is a 4th edition out in market.
wondering if i should buy the new 4th edition book or i am good with the 3rd edition.  For now i just want to concentrate on Objective-C language only.

advice please.

Thanks.

The big change between the two editions has to do with memory management.  The 4th edition covers a feature called ARC (Automated Reference Counting) and there were a lot of changes made to the text because of it.  If you intend to pursue a career with what you're learning, it may be worth your while to get the 4th edition.   The memory management stuff is tough.  While it's still useful to learn about it, as a beginner in Objective-C, it's better left until later if you need to support older code, for example.

Cheers,

Steve

I really do appreciate the way you have presented this specific topic and it also does offer me a lot of fodder for thought.
