不可以。通知在发送它们的同一线程中传递，您需要以某种方式重新发送它才能将通知发送到您的线程。

No.
Apple's docs on the subject say: "Regular notification centers deliver notifications on the thread in which the notification was posted. [...] At times, you may require notifications to be delivered on a particular thread that is determined by you instead of the notification center. [...] In these cases, you must capture the notifications as they are delivered on the default thread and redirect them to the appropriate thread."
The following documentation from Apple might help: https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/Notifications/Articles/Threading.html#//apple_ref/doc/uid/20001289-CEGJFDFG
