是否可以在iPhone的后台运行Safari并监视用户的位置？

问题描述

是否可以在iPhone的后台运行Safari？

具体来说，我们的客户希望通过HTML5 GPS功能监控用户的位置，并测量速度。

在iOS中避免原生实现的原因是因为客户希望使用HTML5创建一个跨平台的服务。

这可能吗？

解决方案

我不相信Safari在后台运行时会继续执行。 （这由上的最近一次线索提供。）

Is it possible to run Safari in the background on the iPhone?

Specifically, our client would like to monitor a user's location via HTML5 GPS capabilities and measure the speed of movement.

The reason for avoiding native implementation in iOS is because the client wishes to create a cross-platform service using HTML5.

Is this possible?

解决方案

I don't believe Safari continues to execute when it's backgrounded. (This is supported by a recent thread on the Apple discussion board.)

That said, it would be fairly trivial to do this in a proper iOS application, although you'd obviously need existing knowledge of Objective-C, some of the main Cocoa/UIKit classes, the Xcode environment, etc.)
