routines and NSThread classes are recommended to create low-level threads, other C-language-based technologies are also available on Mac OS X. Among them, the only one that can be considered is the Multiprocessing Services, which itself is executed on the POSIX thread. The multi-processing service was developed for earlier Mac OS versions. Later, it was applied to the Carbon application in Mac OS X. If you have code that really has this technology, you can continue to use it, although you shoul

threads of thread usage, three kinds of threads each have the advantage. Apple is recommending us to use GCD, because GCD is the most lightweight of these three kinds, and it consumes the lowest resources, and it performs more efficiently than the other two kinds. However, it is better to look at the individual use and development requirements to define.Off-topic: This blog post is the longest I have ever published a technical essay, but also consumes the most energy of the essay, like Friends
