//获取当前设备单例
+ (UIDevice *)currentDevice;
//获取当前设备名称
@property(nonatomic,readonly,strong) NSString *name;
// e.g. "My iPhone"
//获取当前设备模式
@property(nonatomic,readonly,strong) NSString *model;
// e.g. @"iPhone", @"iPod touch"
//获取本地化的当前设备模式
@property(nonatomic,readonly,strong) NSString *localizedModel;
// localized version of model
//获取系统名称
@property(nonatomic,readonly,strong) NSString *systemName;
// e.g. @"iOS"
//获取系统版本
@property(nonatomic,readonly,strong) NSString *systemVersion;
// e.g. @"4.0"
//获取设备方向
@property(nonatomic,readonly) UIDeviceOrientation orientation;
//获取设备UUID对象
@property(nullable, nonatomic,readonly,strong) NSUUID *identifierForVendor;
//是否开启监测电池状态 开启后 才可以正常获取电池状态
@property(nonatomic,getter=isBatteryMonitoringEnabled)
BOOL
batteryMonitoringEnabled NS_AVAILABLE_IOS(3_0);
// default is NO
//获取电池状态
@property(nonatomic,readonly) UIDeviceBatteryState batteryState NS_AVAILABLE_IOS(3_0);
//获取电量
@property(nonatomic,readonly)
float
batteryLevel NS_AVAILABLE_IOS(3_0);

设备方向的枚举如下：

typedef
NS_ENUM(NSInteger, UIDeviceOrientation) {
UIDeviceOrientationUnknown,
UIDeviceOrientationPortrait,
// home键在下
UIDeviceOrientationPortraitUpsideDown,
// home键在上
UIDeviceOrientationLandscapeLeft,
// home键在右
UIDeviceOrientationLandscapeRight,
// home键在左
UIDeviceOrientationFaceUp,
// 屏幕朝上
UIDeviceOrientationFaceDown
// 屏幕朝下
};

电池状态的枚举如下：

typedef
NS_ENUM(NSInteger, UIDeviceBatteryState) {
UIDeviceBatteryStateUnknown,
UIDeviceBatteryStateUnplugged,
// 放电状态
UIDeviceBatteryStateCharging,
// 充电未充满状态
UIDeviceBatteryStateFull,
// 充电已充满
};

下面的方法关于监测屏幕状态：

//获取是否开启屏幕状态更改通知
@property(nonatomic,readonly,getter=isGeneratingDeviceOrientationNotifications)
BOOL
generatesDeviceOrientationNotifications;
//开始监测通知
- (
void
)beginGeneratingDeviceOrientationNotifications;
//结束监测通知
- (
void
)endGeneratingDeviceOrientationNotifications;

下面这两个放大与距离传感器应用相关，可参考：http://my.oschina.net/u/2340880/blog/544341.

@property(nonatomic,getter=isProximityMonitoringEnabled)
BOOL
proximityMonitoringEnabled NS_AVAILABLE_IOS(3_0);
//开启距离传感器
//是否触发了距离传感器
@property(nonatomic,readonly)
BOOL
proximityState
|
相关通知：

//设备方向改变时发送的通知
UIKIT_EXTERN NSString *
const
UIDeviceOrientationDidChangeNotification;
//电池状态改变时发送的通知
UIKIT_EXTERN NSString *
const
UIDeviceBatteryStateDidChangeNotification NS_AVAILABLE_IOS(3_0);
//电量改变时发送的通知
UIKIT_EXTERN NSString *
const
UIDeviceBatteryLevelDidChangeNotification NS_AVAILABLE_IOS(3_0);
//距离传感器状态改变时发送的通知
