如何访问10.9通知中心的功能,如按钮和文本字段？

Answer 1

这里的所有其他答案都需要第三方库; 这个不需要任何东西.它只使用一个苹果脚本来创建通知:

import os

def notify(title, text):
    os.system("""
              osascript -e 'display notification "{}" with title "{}"'
              """.format(text, title))

notify("Title", "Heres an alert")

请注意,此示例不会转义引号,双引号或其他特殊字符,因此这些字符将无法在通知的文本或标题中正常工作.

您应首先使用Ruby 安装terminal-notifier,例如:

$ [sudo] gem install terminal-notifier

然后你可以使用这段代码:

import os

# The notifier function
def notify(title, subtitle, message):
    t = '-title {!r}'.format(title)
    s = '-subtitle {!r}'.format(subtitle)
    m = '-message {!r}'.format(message)
    os.system('terminal-notifier {}'.format(' '.join([m, t, s])))

# Calling the function
notify(title    = 'A Real Notification',
       subtitle = 'with python',
       message  = 'Hello, this is me, notifying you!')

以下为我工作.

import Foundation
import objc
import AppKit
import sys

NSUserNotification = objc.lookUpClass('NSUserNotification')
NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')

def notify(title, subtitle, info_text, delay=0, sound=False, userInfo={}):
    notification = NSUserNotification.alloc().init()
    notification.setTitle_(title)
    notification.setSubtitle_(subtitle)
    notification.setInformativeText_(info_text)
    notification.setUserInfo_(userInfo)
    if sound:
        notification.setSoundName_("NSUserNotificationDefaultSoundName")
    notification.setDeliveryDate_(Foundation.NSDate.dateWithTimeInterval_sinceDate_(delay, Foundation.NSDate.date()))
    NSUserNotificationCenter.defaultUserNotificationCenter().scheduleNotification_(notification)


notify("Test message", "Subtitle", "This message should appear instantly, with a sound", sound=True)
sys.stdout.write("Notification sent...\n")

对于仅Python的实现,我修改了某人发布的代码作为另一个相关问题的一部分,并且对我来说效果很好:

import mmap, os, re, sys
from PyObjCTools import AppHelper
import Foundation
import objc
import AppKit
import time
from threading import Timer

from datetime import datetime, date

# objc.setVerbose(1)

class MountainLionNotification(Foundation.NSObject):
    # Based on http://stackoverflow.com/questions/12202983/working-with-mountain-lions-notification-center-using-pyobjc

    def init(self):
        self = super(MountainLionNotification, self).init()
        if self is None: return None

        # Get objc references to the classes we need.
        self.NSUserNotification = objc.lookUpClass('NSUserNotification')
        self.NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')

        return self

    def clearNotifications(self):
        """Clear any displayed alerts we have posted. Requires Mavericks."""

        NSUserNotificationCenter = objc.lookUpClass('NSUserNotificationCenter')
        NSUserNotificationCenter.defaultUserNotificationCenter().removeAllDeliveredNotifications()

    def notify(self, title, subtitle, text, url):
        """Create a user notification and display it."""

        notification = self.NSUserNotification.alloc().init()
        notification.setTitle_(str(title))
        notification.setSubtitle_(str(subtitle))
        notification.setInformativeText_(str(text))
        notification.setSoundName_("NSUserNotificationDefaultSoundName")
        notification.setHasActionButton_(True)
        notification.setActionButtonTitle_("View")
        notification.setUserInfo_({"action":"open_url", "value":url})

        self.NSUserNotificationCenter.defaultUserNotificationCenter().setDelegate_(self)
        self.NSUserNotificationCenter.defaultUserNotificationCenter().scheduleNotification_(notification)

        # Note that the notification center saves a *copy* of our object.
        return notification

    # We'll get this if the user clicked on the notification.
    def userNotificationCenter_didActivateNotification_(self, center, notification):
        """Handler a user clicking on one of our posted notifications."""

        userInfo = notification.userInfo()
        if userInfo["action"] == "open_url":
            import subprocess
            # Open the log file with TextEdit.
            subprocess.Popen(['open', "-e", userInfo["value"]])

您可能会清理import语句以删除一些不需要的导入.

另一种选择是一个python名为pync的库，也许它是一个更好的选择。pync是terminal-notifier命令行工具的简单 Python 包装器，它允许您将用户通知发送到 Mac OS X 10.10 或更高版本的通知中心。

安装：

pip安装pync

例子：

from pync import Notifier

Notifier.notify('Hello World')
Notifier.notify('Hello World', title='Python')
Notifier.notify('Hello World', group=os.getpid())
Notifier.notify('Hello World', activate='com.apple.Safari')
Notifier.notify('Hello World', open='http://github.com/')
Notifier.notify('Hello World', execute='say "OMG"')

Notifier.remove(os.getpid())

Notifier.list(os.getpid())
