本文从这篇文章修补而来
需要
#import <sys/utsname.h>
接下来是方法

+ (NSString *)getDeviceIdentifier {
    // 需要#import "sys/utsname.h"
    struct utsname systemInfo;
    uname(&systemInfo);
    // 获取设备标识Identifier
    NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    
    if (_antique == -1) {
        NSString *num = [platform componentsSeparatedByString:@","].firstObject;
        int minNum;
        //iPhone和iPad之外的不考虑
        if ([platform containsString:@"iPhone"]) {
            num = [num stringByReplacingOccurrencesOfString:@"iPhone" withString:@""];
            minNum = 9;//iPhone 7
        } else {
            num = [num stringByReplacingOccurrencesOfString:@"iPad" withString:@""];
            minNum = 6;//第一代iPad Pro
        }
        _antique = num.intValue < minNum;
    }
    
    NSDictionary *dic = @{
