objective c - Create a high priority serial dispatch queue with GCD

Question

How can I create a custom serial queue that runs at high priority?

Right now I'm using myQueue = dispatch_queue_create("com.MyApp.MyQueue", NULL); but this doesn't seem to allow for setting a priority?

Answer 1

Create a serial queue, then use dispatch_set_target_queue() to set its target queue to the high priority queue.

Here's how:

dispatch_set_target_queue(myQueue, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0));

Now myQueue should run serially with high priority. Here's another SO answer if you want to know more.
