问题描述

我想用Cocoa显示当前的曲目标题。

I want to display a current track title with Cocoa.

现在我可以使用Scripting Bridge获得标题，但我不知道如何获得

For now I could get the playing title with Scripting Bridge but I don't know how to get it just after a song is changed.

有没有任何方法可以在没有计时器的情况下将监听器挂接到iTunes。

Is there any way I can hook a listener to iTunes without a timer.

iTunes在轨道变化时发布分布式通知。 此问题< a>包含有关您需要遵守的通知的信息，您应该能够根据接受的答案中的Python代码或其他答案所链接的Objective-C代码来确定您需要做什么。

iTunes posts a distributed notification when the track changes.
