Chapter 15. Threads
Java was one of the first programming languages to support threads and thread synchronization directly. It was a very forward-looking decision. Multicore, multiprocessor computer systems have become the norm, rather than the exception. Efficient multi-threaded programming is now essential to effective program development, and it's a trend that continues to accelerate.
Threads and semaphores are conceptually simple, and the high-level differences between Java and Objective-C are trivial. Objective-C also makes extensive use of run loops, which transform a thread into an event processor. Beyond the basic @synchronize directive built into the language, the Cocoa framework provides a number of additional synchronization tools, each ...
