使用GCD创建高优先级的串行调度队列 [英] Create a high priority serial dispatch queue with GCD

问题描述

如何创建以高优先级运行的自定义串行队列?

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

现在我正在使用myQueue = dispatch_queue_create("com.MyApp.MyQueue", NULL);，但这似乎不允许设置优先级吗?

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

推荐答案

创建一个串行队列，然后使用dispatch_set_target_queue()将其目标队列设置为高优先级队列.

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

方法如下:

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

现在，myQueue应该以高优先级顺序运行. 如果您想了解更多信息，请另一个SO答案.

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