为特定的NSThread创建GCD队列

Question

I would like to create a thread for offline rendering with its own OpenGL context.

For submitting rendering tasks, I would like to use GCD, due to its API simplicity.

Is it possible to create a GCD queue that is attached to a specific NSThread (which has its own OpenGL context)?

It seems to be possible, since the main queue always runs it tasks on the main thread, but I could not find anything with similar behavior for custom threads.

You can set the current context at the beginning of every task, as described here: "OpenGL Restricts Each Context to a Single Thread" .

You can also set a context for the dispatch queue, as explained here .
