If you don't understand run loops (what they are, how they work, under what circumstances they are created and run for you, when you need to explicitly run them yourself), then you need to spend some time learning about them, especially before departing from the standard Cocoa application template. I wouldn't worry about more advanced topics like NSOperation or NSOperationQueue until mastering a bit more of the basics. http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Multithreading/RunLoopManagement/RunLoopManagement.html%23//apple_ref/doc/uid/10000057i-CH16-SW1 http://www.mikeash.com/pyblog/friday-qa-2010-01-01-nsrunloop-internals.html _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
