一、距离传感器的开启关闭

//判断距离传感器状态
            if ([[UIDevice currentDevice] proximityState] == NO)
            {
                //打开距离传感器
                [[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
                
            }

//传感器的关闭

[[UIDevice currentDevice] setProximityMonitoringEnabled:NO];

二、传感器状态发生改变调用方法

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(funName:)
                                             name:UIDeviceProximityStateDidChangeNotification
                                           object:nil];

三、与设备相关的三个通知

UIKIT_EXTERN NSString *const UIDeviceOrientationDidChangeNotification __TVOS_PROHIBITED;
UIKIT_EXTERN NSString *const UIDeviceBatteryStateDidChangeNotification   NS_AVAILABLE_IOS(3_0) __TVOS_PROHIBITED;
UIKIT_EXTERN NSString *const UIDeviceBatteryLevelDidChangeNotification   NS_AVAILABLE_IOS(3_0) __TVOS_PROHIBITED;
UIKIT_EXTERN NSString *const UIDeviceProximityStateDidChangeNotification NS_AVAILABLE_IOS(3_0);
