Question

I was testing performSelector:onThread:withObject:waitUntilDone: for inter-thread communication as recommended by Matt Ghallagher’s tutorial. Turns out that it is extremely slow, and pretty much no good for real time audio applications. Any suggestions?

Answer 1

On the main thread:

AnyClass myObject;

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
   // do asynchronous work
   // environment objects and variables will be available
   [myObject doSomething];
});

It really does not get any simpler than that…
