iPhone应用程序在后台 [英] iPhone app in the background

问题描述

有没有办法从关闭的iPhone应用程序启动声音或弹出消息。
简单地说就像接收短信

Is there any way to start sound or pop-up message from closed iPhone app. Simply like "receive SMS"

推荐答案

我不相信。 Apple声称没有第三方应用程序可以在后台运行（即使他们的一些应用程序这样做）。这就是为什么去年夏天有很多关于推送通知的原因（不幸的是，这已经不存在了） - 这将允许应用程序从服务器发送一些数据，然后适当地响应它。

I don't believe so. Apple has stated that no third party apps can run in the background (even though some of their apps do this). This is why there was a big deal about "push notifications" last summer (that has since gone no where, unfortunately) - this would allow an app to be sent some data from a server, and then appropriately respond to it.

如果您为越狱的iPhone编写应用程序，您可能能够完成此任务，但只有那些已经越狱手机的用户才能安装和使用您的应用程序。

You might be able to accomplish this if you write an app for a jailbroken iPhone, but then only those users who have jailbroken their phone would be able to install and use your app.
