GCD obtaining queue name/label

问题

How can I get the current queue name?

I mean queue label like com.example.myqueue.

In the Xcode 4 debugger I can see just _block_invoke_1.

回答1:

How about dispatch_queue_get_label?

回答2:

In Objective-C you can log the label of the current queue with:

NSLog(@"%s", dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL));

In Swift (2.0):

print(String(UTF8String: dispatch_queue_get_label(DISPATCH_CURRENT_QUEUE_LABEL))!)
