iOS获取和监测设备基本信息——UIDevice的使用
//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 UIKIT_EXTERN NSString *const UIDeviceProximityStateDidChangeNotification NS_AVAILABLE_IOS(3_0);
