NSThread 的产量？

我有一个 NSOperationQueue，我想取消一些操作。因此我迭代操作并取消一些任务。在同一（UI）线程中随后执行的代码中的另一点，我检查队列中有多少操作。即使我取消所有操作，我也永远不会得到0。我猜这些操作需要正确处理取消。因此，我需要在取消后在我的 UI 线程中调用某种“yield”函数。有没有办法在 Cocoa Touch 中做到这一点？

我相当黑客的解决方案是取消后：

[NSThread sleepForTimeInterval:0.1];

知道如何让它变得更好吗？

谢谢，拉尔斯

原文

I have an NSOperationQueue and I want to cancel some operations. Therefore I iterate over the operation and cancel some tasks. At another point in the code which is executed subsequent in the same (UI) thread I check how many operations are in the queue. Even if I cancel all operations I get never 0. I guess the operations need to process the cancel properly. Therefore I would need some kind of "yield" function called in my UI thread after canceling. Is there a way to do that in Cocoa Touch?

My rather hackish solution is after cancel is:
