关于iphone中的Ambient Light传感器 [英] About Ambient Light sensor in iphone

问题描述

提前致谢。

我从 http://ipod.about.com/od/ipodiphonehardwareterms/qt/iphone-sensors.htm 。但我没有得到有关如何在iphone中使用环境传感器的信息

I got the information about the iphone sensors from http://ipod.about.com/od/ipodiphonehardwareterms/qt/iphone-sensors.htm. But I didn't get information about how to use ambient sensor in iphone

推荐答案

这是可能的，而且框架是公开的。

It is possible, and the framework is public.

您可以激活与传感器的连接，如下所示：

You can activate the connection to the sensor like so :

[[UIDevice currentDevice] setProximityMonitoringEnabled:YES]; 

BTW，它似乎没有使用光传感器，因为接近感应会调整到一个黑暗的房间。

BTW, it doesn't seem to be using the light sensor, because proximity sensing would tweak out in a dark room.

然而，当您将手机放在脸上时，API调用基本上会使屏幕空白。遗憾的是，没有用于互动。

However, the API call basically blanks the screen when you hold the phone up to your face. Not useful for interaction, sadly.
