本文介绍了如何在iOS中利用UIDevice类获取设备信息，包括操作系统版本、设备型号等，适用于Xcode 6.1及iOS 8.1环境下，以iPhone 4s（iOS 7.1.1）为例，提供了相应的代码示例。

获取iOS设备信息需要用到UIDevice类，UIDevice.h文件定义了这些属性：

@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);

下面通过简单例子介绍这些属性！

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);
    NSLog(@"设备本地模式 - %@", myDevice.localizedModel);
    NSLog(@"系统名称 - %@", myDevice.systemName);
    NSLog(@"系统版本 - %@", myDevice.systemVersion);
    
//    typedef NS_ENUM(NSInteger, UIDeviceOrientation) {
//        UIDeviceOrientationUnknown,
//        UIDeviceOrientationPortrait,            // Device oriented vertically, home button on the bottom
//        UIDeviceOrientationPortraitUpsideDown,  // Device oriented vertically, home button on the top
//        UIDeviceOrientationLandscapeLeft,       // Device oriented horizontally, home button on the right
//        UIDeviceOrientationLandscapeRight,      // Device oriented horizontally, home button on the left
//        UIDeviceOrientationFaceUp,              // Device oriented flat, face up
//        UIDeviceOrientationFaceDown             // Device oriented flat, face down
//    };
    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) {
//        UIDeviceBatteryStateUnknown,
//        UIDeviceBatteryStateUnplugged,   // on battery, discharging
//        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
}
