how to run my application in background in iphone?
提问by Rahul Vyas
I want to run my timer in background even when app is not running. Because I want to get gps cordinate of the user after some time interval. What is the method to do this?
即使应用程序未运行，我也想在后台运行我的计时器。因为我想在一段时间后获得用户的 gps 坐标。这样做的方法是什么？

I don't think this is allowed in the iPhone programming paradigm. The operating system is capable of running background tasks but ordinary iPhone apps are not permitted to launch anything like this.
我认为这在 iPhone 编程范式中是不允许的。该操作系统能够运行后台任务，但不允许普通的 iPhone 应用程序启动此类任务。

The Apple Push Notification service is not, in fact, only available to a few developers. It is currently in wide-spread use.
实际上，Apple 推送通知服务并非仅对少数开发人员可用。目前它被广泛使用。
Take a look at this:
看看这个：
The "Registering for remote notifications" section specifies how to register for push notifications. The other end is set up in the iPhone developer portal.
“注册远程通知”部分指定了如何注册推送通知。另一端设置在 iPhone 开发者门户中。

Not possible without jailbreak - iphone sdk apps can only run while on screen.
没有越狱是不可能的 - iphone sdk 应用程序只能在屏幕上运行。

It only works on jail broke phones, another way it to use push notification from our servers for timed tasks. Why dont you use this, to wake up the app get the GPS then send it back to sleep. Better for batteries too.
它仅适用于越狱手机，另一种使用来自我们服务器的推送通知来执行定时任务的方式。你为什么不使用它，唤醒应用程序获取 GPS 然后将其发送回睡眠状态。对电池也更好。
