如何实用的iOS Push通知

[英]How Practical iOS Push notification

原文 2011-11-27 07:25:53 2 1 ios

My understanding is that iOS Push notification have limitation: 我的理解是iOS Push通知有局限性：

Do not guarantee delivery. 不保证交货。
And there might be delay in receving these notification. 接收这些通知可能会有所延迟。

Considering these limitation, I was thinking that application such as WhatsApp messenger will not be practical. 考虑到这些限制，我认为像WhatsApp Messenger这样的应用程序将不实用。 But it seems iOS Push notification is not bad. 但似乎iOS Push通知还不错。 Hence, My question is: 因此，我的问题是：

In practice, how reliable iOS Push notification , for example, 99%? 实际上，iOS Push通知的可靠性如何，例如99％？
Usually, how long notification delivery it takes , for example, < 1 minute? 通常，通知传递需要多长时间，例如，不到1分钟？

Thanks in advance 提前致谢

Generally it is reliable, in my experience (I have written 5 apps using push over the past 4 years) they get delivered > 99% of the time and within just a several seconds. 通常来说，它是可靠的，根据我的经验（在过去的4年中，我使用push编写了5个应用），它们在短短几秒钟内的交付率> 99％。 Note that there are serious issues though with background push in iOS8. 请注意，尽管iOS8中的背景推送功能存在严重问题。 But if you are just using foreground push its reliable though not 100% guaranteed of course. 但是，如果您仅使用前景推，则当然不能保证100％保证其可靠。
