线程间通信的方式比performSelector更简单：onThread：withObject

Question

我正在按照Matt Ghallagher performSelector:onThread:withObject:waitUntilDone:的建议测试tutorial进行线程间通信。事实证明，对于实时音频应用来说，它非常慢，而且几乎no good。有什么建议？

Answer 1

在主线上：

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];
});

它真的没有比那更简单......
