作为一个新的发展者,我从未使用过方向。 因此,我要尝试以简单的任务学习。 我想要做的是,当该装置被 down倒时,就会有黑色。 也许有些人可以帮助我,或提供有用的信息,这是否简单易行?
Thanks! :D Your help is appriciated
You can use orientation (using the XYZ values when the screen is face down). I do not recommend this, because your screen will fade out even if a user is using the app while lying down, and staring up at the screen.
比较容易和更清洁。 在电话中,把电话贴近你的耳光的黑人,如何通知?
可以通过监测<代码>proximityState Property of UIDevice,查阅该财产。 详情here
Doing something like:
BOOL closeToUser = [[UIDevice currentDevice] proximityState];
将指定一个<代码>YES,以关闭 装置在某种表面上被压倒的用户,以及<代码> NO 不适用
如果价值是YES,你可以援引代码来做你想要的一切。
