I ran into an interesting thread on the Cocoa Developers discussion group, and thought I 'd try to create a small demo, to see what I could learn, and sure enough I learned a lot. There were quite a few people that participated and provided a lot of great information, I tried to quote the email messages, and give credit to the people that provided some of the code, and the insights. I hope I didn’t leave any one out, if I did, it was not intentional.
On my website the tutorial is listed under the following :
http://www.journey-of-flight.com/index.php
Cocoa - Generating Unique ID Strings
or you can reach the page directly at :
http://www.journey-of-flight.com/bh_xcode/how-to/0086_Unique_ID/index.php
I also added a resources link at :
http://www.journey-of-flight.com/bh_xcode/common/cocoa_programming_resources.php
if you see any that I should add, please let me know.
Hope this is useful
