当程序在后台iOS 4的通知 [英] notification when program is in background iOS 4

问题描述

我们正在寻找一种方式来超时iPhone应用程序，并尝试了好几种方法：

We are looking for a way to timeout an iPhone application, and have tried several methods:

这一个动作后复位的NSTimer
LocalNotification，一个动作之后重置

NSTimer that resets after an action LocalNotification that resets after an action

两者比较接近，但是从独特的问题的影响：

Both are close, but suffer from unique issues:

的NSTimer：当手机睡觉，定时器将不火
LocalNotification：当应用程序在后台运行，显示通知，我们没有办法让应用程序有接收通知

NSTimer: When the phone sleeps, the timer will not fire LocalNotification: When the app is in the background, the notification is displayed, we don't have a way to have the application have to receive the notification.

询问组，如果这听起来正确的，或者如果有也许有些点以上，我很想念，将允许这个工作。

Asking the group if this sounds correct, or if there is maybe some point above that I am missing that would allow this to work.

在此先感谢！

推荐答案

您知不知道，当你的应用程序是处于暂停状态，您将不会收到任何通知 - 这是文件的权利，只有目前只有3类，可以接收通知应用程序：音频应用程序（如iPod和类似物），基于位置的应用程序和VoIP应用。你的plist中，必须正确设置，如果你的应用程序是这些应用程序之一。

You do realize that when your app is in a suspended state, you won't receive any notifications -- and this is right in the documentation. There are only 3 classes of applications that can receive notifications: Audio applications (like iPod and analogues), location based applications, and voip apps. Your plist has to be set up correctly if your app is one of those applications.
