ios - GCD和外线程

Question

有没有办法可以创建一个新的(或关联现有的)调度队列并将其绑定(bind)到特定线程？

我有一个 AudioUnit 回调过程在一个我无法控制的线程上运行，并且希望在正确执行回调之前，检查某个给定队列是否有任何 block 供我在该 AudioUnit 线程内处理。

我可能可以使用 OSAmtomicEnqueue 和 friend ，但想知道 GCD 是否已经提供了某种“转义”，允许我将特定线程绑定(bind)到特定队列？

Answer 1

根据 Apple 文档，答案是否定的。

GCD provides and manages FIFO queues to which your application can submit tasks in the form of block objects. Blocks submitted to dispatch queues are executed on a pool of threads fully managed by the system. No guarantee is made as to the thread on which a task executes.
