获取iOS设备信息需要用到UIDevice类,UIDevice.h文件定义了这些属性:
下面通过简单例子介绍这些属性!
- @property(nonatomic,readonly,retain) NSString *name; // e.g. "My iPhone"
- @property(nonatomic,readonly,retain) NSString *model; // e.g. @"iPhone", @"iPod touch"
- @property(nonatomic,readonly,retain) NSString *localizedModel; // localized version of model
- @property(nonatomic,readonly,retain) NSString *systemName; // e.g. @"iOS"
- @property(nonatomic,readonly,retain) NSString *systemVersion; // e.g. @"4.0"
- @property(nonatomic,readonly) UIDeviceOrientation orientation; // return current device orientation. this will return UIDeviceOrientationUnknown unless device orientation notifications are being generated.
- @property(nonatomic,readonly,retain) NSUUID *identifierForVendor NS_AVAILABLE_IOS(6_0); // a UUID that may be used to uniquely identify the device, same across apps from a single vendor.
- @property(nonatomic,readonly,getter=isGeneratingDeviceOrientationNotifications) BOOL generatesDeviceOrientationNotifications;
- @property(nonatomic,getter=isBatteryMonitoringEnabled) BOOL batteryMonitoringEnabled NS_AVAILABLE_IOS(3_0); // default is NO
- @property(nonatomic,readonly) UIDeviceBatteryState batteryState NS_AVAILABLE_IOS(3_0); // UIDeviceBatteryStateUnknown if monitoring disabled
- @property(nonatomic,readonly) float batteryLevel NS_AVAILABLE_IOS(3_0); // 0 .. 1.0. -1.0 if UIDeviceBatteryStateUnknown
- @property(nonatomic,getter=isProximityMonitoringEnabled) BOOL proximityMonitoringEnabled NS_AVAILABLE_IOS(3_0); // default is NO
- @property(nonatomic,readonly) BOOL proximityState NS_AVAILABLE_IOS(3_0); // always returns NO if no proximity detector
- @property(nonatomic,readonly,getter=isMultitaskingSupported) BOOL multitaskingSupported NS_AVAILABLE_IOS(4_0);
- @property(nonatomic,readonly) UIUserInterfaceIdiom userInterfaceIdiom NS_AVAILABLE_IOS(3_2);
环境:Xcode 6.1,iOS 8.1
设备:iPhone 4s(iOS 7.1.1)
代码如下:
- // 获取设备信息
- - (void) getDevInfo
- {
- UIDevice* myDevice = [UIDevice currentDevice];
- NSLog(@"设备名称 - %@", myDevice.name);
- NSLog(@"设备模式 - %@", myDevice.model);

- // typedef NS_ENUM(NSInteger, UIDeviceOrientation) {

- // UIDeviceOrientationLandscapeRight, // Device oriented horizontally, home button on the left

- // };
- NSLog(@"设备朝向 - %d", myDevice.orientation); // 详见UIDeviceOrientation
- NSLog(@"设备UUID - %@", myDevice.identifierForVendor);
- // 当前设备是否有转向通知
- NSLog(@"设备转向通知(BOOL) - %hhd", myDevice.generatesDeviceOrientationNotifications);
- // 是否启动电池监控,默认为NO
- NSLog(@"电池监控启用状态(BOOL) - %hhd", myDevice.batteryMonitoringEnabled);
- // typedef NS_ENUM(NSInteger, UIDeviceBatteryState) {

- // UIDeviceBatteryStateCharging, // plugged in, less than 100%
- // UIDeviceBatteryStateFull, // plugged in, at 100%
- // }; // available in iPhone 3.0
- NSLog(@"电池状态 - %d", myDevice.batteryState); // 详见UIDeviceBatteryState
- // 电量百分比, 0到1.0,如果电池状态为UIDeviceBatteryStateUnknown,则百分比为-1.0
- NSLog(@"电池电量 - %f", myDevice.batteryLevel);
- // 是否启动接近监控(比如脸接近手机屏),默认为NO
- NSLog(@"接近监控启用状态(BOOL) - %hhd", myDevice.proximityMonitoringEnabled);
- // 如果没有接近感应器,则返回NO
- NSLog(@"接近状态(BOOL) - %hhd", myDevice.proximityState);
- NSLog(@"是否支持多任务(BOOL) - %hhd", myDevice.multitaskingSupported);
- // typedef NS_ENUM(NSInteger, UIUserInterfaceIdiom) {
- // UIUserInterfaceIdiomUnspecified = -1,
- //#if __IPHONE_3_2 <= __IPHONE_OS_VERSION_MAX_ALLOWED
- // UIUserInterfaceIdiomPhone, // iPhone and iPod touch style UI
- // UIUserInterfaceIdiomPad, // iPad style UI
- //#endif
- // };
- NSLog(@"用户界面模式 - %d", myDevice.userInterfaceIdiom); // 详见UIUserInterfaceIdiom
