运行iOS应用程序与屏幕锁定 [英] Running IOS App with Screen Locked

问题描述

我正在使用GPS和OpenEars文本到语音的运动应用程序。该应用程序提供了速度和其他GPS信息可听用户（通过耳机），使用户（滑雪，骑自行车等），可以得到GPS信息，而不看屏幕。为了节省电池寿命，我想应用与屏幕关闭后台运行。这可能与IOS？我尝试设置必需backgrund模式GPS和音频，但我的应用程序退出时，屏幕关闭工作。

I am working on a sports app that uses GPS and OpenEars text-to-speech. The app delivers speed and other GPS info to the user audibly (via earphones) so the user (skier, cyclist, etc) can get the GPS info without looking at the screen. In order to save battery life, I would like the app to run in the background with the screen off. Is this possible with IOS? I tried setting "Required backgrund modes" for both GPS and audio, but my app quits working when the screen is off.

感谢..
