观察者通知的NSNotification顺序 [英] NSNotification order of observer notifications

问题描述

如果我有几个类观察特定的NSNotification，那么观察者在发布通知时会以什么顺序通知？

If I have several classes observing a particular NSNotification, in what order are the observers notified when the notification is posted?

推荐答案

无法保证发出的订单通知。如果您需要订购，您可能需要创建一个监听一个通知的类，并发出其他类可以监听的多个有序通知。

There is no guarantee as to what order notifications are sent out. If you need an ordering you may want to create a class that listens for one notification and sends out multiple ordered notifications that other classes can listen for instead.
