问题描述

我正在尝试利用iPhone 4多任务处理功能。我想在后台运行app并经常发送http请求发送/接收数据，是否可能？

I am trying to take advantage of iPhone 4 multitasking feature. I want to run app in background and frequently send http request to send/receive data, is it possible?

推荐答案

这是可能的在应用程序后台运行时请求运行时间。

It is possible to request running time while your app is backgrounded.

参见多任务处理开发人员指南

虽然根据您的http请求的意图，推送通知可能是一种可行的选择。

Although, depending on the intent of your http requests, push notifications may be a viable alternative.

这可能是必要的，因为您不提供音频，voip或位置服务，因此您的应用无法无限期地在后台运行。

This may be necessary because you aren't providing audio, voip, or location services, so your app can't run in the background indefinitely.
