How to schedule operation on background thread [Cocoa]

With Cocoa, how can I schedule an operation (block of code) to run asynchronously on a background thread?

There is a risk that the operation will block for a long time, so it is of critical importance that the operation is not executed on the main thread.

Of course, I can create my own thread (NSThread), but it seems to me that Cocoa should offer an easier/better way.

You can use the Grand Central Dispatch command dispatch_async() to easily run code in the background. An example of this:

dispatch_queue_t bgQueue = dispatch_queue_create("bgQueue", NULL);
dispatch_async(bgQueue, ^{
    //your code here
});
