使用 PyObjC 使用 Mountain Lion 的通知中心 [英] Working with Mountain Lion's Notification Center using PyObjC

问题描述

我正在尝试从我的 Python 脚本向 Mountain Lion 发送通知，并对点击通知做出反应.发送通知工作完美找到现在.但是我无法让 Lion 在单击时回调我的脚本.

I'm trying to send notifications to Mountain Lion from my python script and react to clicks on the notifications. Sending the notifications works perfectly find by now. But yet I was not able to get Lion to call back my script upon a click.

这就是我所做的.我实现了一个通知类.该类的实例的唯一目的是通过调用 notify() 来提供通知.在相同的方法中，我设置了应用程序的委托对象.

Here is what I do. I implemented a Notification class. The only purpose of an instance of that class is to provide notifications by invoking notify(). In the same method I set the object the app's delegate.

import Foundation
import objc
import AppKit

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.setUserInfo_({"action":"open_url", "value":url})
        AppKit.NSApplication.sharedApplication().setDelegate_(self)
        NSUserNotificationCenter.defaultUserNotificationCenter().scheduleNotification_(notification)

    def applicationDidFinishLaunching_(self, sender):
        userInfo = sender.userInfo()
        if userInfo["action"] == "open_url":
            import subprocess
            subprocess.Popen(['open', userInfo["value"]])

现在我希望在单击通知时调用 applicationDidFinishLaunching_().不幸的是，这永远不会发生.我做错了什么?

Now I expected applicationDidFinishLaunching_() to be called upon a click on the notification. Unfortunately that never happens. What am I doing wrong?

推荐答案

好的，找到了.没有运行 AppHelper.runEventLoop().显然是面部错误.以下代码有效:

Ok, found it. Didn't run AppHelper.runEventLoop(). Obviously a facepalm mistake. The following code works:

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"]])
