在开发过程中有时需要获取设备具体型号然后进行不同的适配。
目前我们的在适配iOS设备主要分为UI方面的适配，比如iPhone5 、iPhone6、iPhone6 Plus、iPhoneX、iPhoneXS Max，具体的UI在这些屏幕的适配上都是不一样的。
部分APP还适配了iPad，适配iPad与iPhone 的UI 又不一样。
目前还有一部分的设备是需要获取具体的设备名称，比如我们通过代码获取设备的名称iPhone6,1，但对应的我们经常口头说的设备却并不是iPhone6，其实质对应的是我们最经典的iPhone5。
那么我们如何对应这些需求呢？
设备屏幕类型
我们一般通过宏的定义来区分具体的iPhone和iPad设备类型UI。
首先是我们如何区分iPad和iPhone设备。
// iPhone 设备
#define kUI_IPHONE ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
// iPad 设备
#define kUI_IPAD ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
具体可以参考代码中的枚举值
typedef NS_ENUM(NSInteger, UIUserInterfaceIdiom) {
UIUserInterfaceIdiomUnspecified = -1,
UIUserInterfaceIdiomPhone NS_ENUM_AVAILABLE_IOS(3_2), // iPhone and iPod touch style UI
UIUserInterfaceIdiomPad NS_ENUM_AVAILABLE_IOS(3_2), // iPad style UI
UIUserInterfaceIdiomTV NS_ENUM_AVAILABLE_IOS(9_0), // Apple TV style UI
UIUserInterfaceIdiomCarPlay NS_ENUM_AVAILABLE_IOS(9_0), // CarPlay style UI
};
一般情况下iPad设备一套UI 基本能够适配所有的iPad设备的UI类型，因为Mini系列 Air系列包括目前的新款全面屏其宽高比基本都是一致的。很少的情况去做特殊的UI适配。
首先是我们如何区分iPhone设备不同的UI类型。
// iPhone4 和4s系列
#define kUI_IPHONE4 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
// iPhone5 和5s系列
#define kUI_IPHONE5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
// iPhone6 和6s系列（包括6，7，8三代产品）
#define kUI_IPHONE6 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(750, 1334), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
// iPhone6 Plus 和6s Plus系列（包括6，7，8三代产品）
#define kUI_IPHONE6PLUS ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2208), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
//判断iPHoneXr (CGSizeMake(828, 1792) 启动图 CGSizeMake(750, 1624) 无启动图
#define kUI_IPhoneXR ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? (CGSizeEqualToSize(CGSizeMake(828, 1792), [[UIScreen mainScreen] currentMode].size)|| CGSizeEqualToSize(CGSizeMake(750, 1624), [[UIScreen mainScreen] currentMode].size))&& kUI_IPHONE : NO)
//判断iPhoneXs 和iPhoneX
#define kUI_IPhoneXS ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1125, 2436), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
//判断iPhoneXs Max
#define kUI_IPhoneXSMAX ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(1242, 2688), [[UIScreen mainScreen] currentMode].size) && kUI_IPHONE : NO)
//判断是否是X全系列 留海屏幕
#define kUI_IPhoneX (kUI_IPhoneXR ||kUI_IPhoneXS ||kUI_IPhoneXSMAX)
目前主要是iPhoneX系NaviBar 、 Tabbar 和StatusBar 的高度与其他系列都不一样，所以一般情况下还是有高度也有不一样
//iPhoneX系列
#define kStatusBarHeight (kUI_IPhoneX ? 44.0 : 20.0)
#define kNaviBarHeight (kUI_IPhoneX ? 88.0 : 64.0)
#define kTabBarHeight (kUI_IPhoneX ? 83.0 : 49.0)
获取设备类型名称
我们通过代码获取的设备硬件编码字符串是"iPhone6,1"，其实这里面有三个参数， 每个参数都是有具体的含义的。
1、iPhone 代表的是具体的设备类型，比如iPhone代表手机，iPad代表平板
2、6 代表的是具体的设备版本，其中6对应的是iPhone手机5代产品，即我们常说的iPhone 5
3、1 代表销售地区和网络型号，例如"iPhone6,1"中的1表示只在美国、加拿大、墨西哥等地区销售的LTE 网络类型设备，其中2表示其他国家销售的苹果设备，但是也一样在美国和加拿大地区销售。
具体代码如下
#import <sys/utsname.h>
+ (NSString *)deviceModelName{
struct utsname systemInfo;
uname(&systemInfo);
NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
