苹果没有提供大量关于有多少用户实际接受/拒绝推送通知的信息，但您可以通过比较总安装数和您拥有的有效推送通知令牌的数量来很好地了解正在发生的情况（我是假设由于您对分析感兴趣，因此您已经设置了推送服务器）只有在用户接受时才会生成推送通知令牌。
如果您需要有关实际推送通知的更多信息，您需要亲自动手并在应用程序中实际添加跟踪代码。如果您正在寻找免费的工具，请尝试使用具有自定义事件跟踪功能的 iOS 版 Google Analytics：https://developers.google.com/analytics/devguides/collection/ios/v2/events
Urban Airship 还提供了相当不错的分析服务，但您必须使用他们的推送通知服务器：http://urbanairship.com/products/push-messaging#analyze
Apple does not provide a lot of information about how many users actually accept/decline push notifications but you can get a good idea of what's going on by comparing the number of total installs and the number of valid push notification tokens you have ( I'm assuming that since you are interested in analytics you already have a Push server set up ) Push notification tokens are only generated if a user accepts.
If you need more information about the actual push notifications, you'll need to get your hands dirty and actually add tracking code in the application. If you're looking for something free try Google Analytics for iOS with Custom Event Tracking: https://developers.google.com/analytics/devguides/collection/ios/v2/events
Urban Airship also provides a pretty good analytics service, but you have to be using their push notification server: http://urbanairship.com/products/push-messaging#analyze
