aotorelease对象具体是什么时候释放？

The autoreleased objects will be deallocated when, the closest enclosing autorelease pool on the stack of the thread on which the -autorelease message has been sent, gets drained or released.

对于每一个Runloop， 系统会隐式创建一个Autorelease pool，这样所有的release pool会构成一个象CallStack一样的一个栈式结构，在每一个Runloop结束时，当前栈顶的Autorelease pool会被销毁，这样这个pool里的每个Object会被release。

关于Runloop，请问文档：
