防止iPhone入睡 [英] Prevent iPhone to sleep

问题描述

我在应用程序中使用了加速度计，并且正在使用[UIApplication sharedApplication].idleTimerDisabled = YES;来防止设备进入睡眠状态.它可以正常工作，但是通过这种方式屏幕始终处于全亮状态，有没有一种方法可以防止设备进入睡眠状态并保持节能模式? 当idleTimerDisabled设置为NO时，设备在睡眠前进入节能模式，我只想防止设备进入睡眠状态并保持节能.有办法吗?

I using accelerometer in my app and i'm using [UIApplication sharedApplication].idleTimerDisabled = YES; to prevent the device to sleep. It works fine, but this way the screen is always on full bright, there is a way to prevent the device to sleep and keep the energy economy mode on? When idleTimerDisabled is stetted to NO the device enter in the energy economy mode before sleep, i just want to prevent the device to sleep and keep the energy economy. There is a way to do that?

推荐答案

有一个UIScreen实例brightness的属性，可能是您想要的.查看UIScreen的brightness属性的文档

There's a property of UIScreen instances, brightness, that is likely what you want. Check out the documentation of UIScreen's brightness property here.

尝试:

[[UIScreen mainScreen] setBrightness: 0.3];
