iOS获取设备名称

苹果在获取设备名称这一点上做的确实不够人性化,比如我的设备是iPhone XR,根据#import <sys/utsname.h>框架获取的字段是iPhone11,8,这一般人看不出什么门道,实际上它代表的是手机固件的版本

struct utsname systemInfo;
    uname(&systemInfo);
    // 获取设备标识Identifier即类似于"iPhone11,8"这种字符串
    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

网上很多维护通过Identifier去翻译设备名称的胶水代码,新出的机型很多文章或者代码都不及时更新的,毕竟维护成本在那里,确实没啥特别好的办法,但是有没有什么一劳永逸的办法呢,好像目前并没有~
但是所幸找到以下两个网站比较全面且可以作为参考的:
https://www.theiphonewiki.com/wiki/Models
https://ipsw.me
以及API接口 https://api.ipsw.me/v4/devices

等苹果发布新品之后,一般这些网站会同步更新,只要对着更新对应的匹配规则即可
通过上面<sys/utsname.h>可以拿到类似iPhone11,8这种Identifier字段可以遍历匹配https://api.ipsw.me/v4/devices 这个接口返回的数据,请求一次缓存起来使用即可,有新品发布时再搞更新策略啥的
//类似于这样通过identifier匹配对应的name字段即可
