好，找到了。没有跑
AppHelper.runEventLoop()。显然是facepalm错误。以下代码有效：
class MountainLionNotification(Foundation.NSObject, Notification): def notify(self, title, subtitle, text, url): NSUserNotification = objc.lookUpClass('NSUserNotification') NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter') notification = NSUserNotification.alloc().init() notification.setTitle_(str(title)) notification.setSubtitle_(str(subtitle)) notification.setInformativeText_(str(text)) notification.setSoundName_("NSUserNotificationDefaultSoundName") notification.setHasActionButton_(True) notification.setOtherButtonTitle_("View") notification.setUserInfo_({"action":"open_url", "value":url}) NSUserNotificationCenter.defaultUserNotificationCenter().setDelegate_(self) NSUserNotificationCenter.defaultUserNotificationCenter().scheduleNotification_(notification) def userNotificationCenter_didActivateNotification_(self, center, notification): userInfo = notification.userInfo() if userInfo["action"] == "open_url": import subprocess subprocess.Popen(['open', userInfo["value"]])
