每一种 iOS 设备型号都有对应的一个或多个硬件编码/标识符，称为 device model 或者叫 machine name
通常的做法是，先获取设备的 device model 值，再手动映射为具体的设备型号（或者直接把 device model 值传给后端，让后端去做映射，这样的好处是可以随时兼容新设备）。
完整的 device mode 数据参考 Wiki：https://www.theiphonewiki.com/wiki/Models
我们可以先获取 device model 值，记为 internalName ，然后进行对比判断，转换成具体的设备型号。实现代码如下图所示：
objectivec
+ (NSString *)deviceName {
struct utsname systemInfo;
uname(&systemInfo);
NSString *internalName = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
NSDictionary *dict = @{
