1.导入头文件：

#import <sys/utsname.h>

2.在 要获取的方法中添加：

struct utsname systemInfo;
uname(&systemInfo);
NSString *model = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];
NSString *deviceModelName = [self currentModel:model];
NSLog(@"%@\n", model);

3。 model 就是对应的手机型号， 然后拿到 model 进行判断

- (NSString *)currentModel:(NSString *)phoneModel {

if ([phoneModel isEqualToString:@"iPhone3,1"] ||
    [phoneModel isEqualToString:@"iPhone3,2"])   return @"iPhone 4";
if ([phoneModel isEqualToString:@"iPhone4,1"])   return @"iPhone 4S";
if ([phoneModel isEqualToString:@"iPhone5,1"] ||
    [phoneModel isEqualToString:@"iPhone5,2"])   return @"iPhone 5";
if ([phoneModel isEqualToString:@"iPhone5,3"] ||
    [phoneModel isEqualToString:@"iPhone5,4"])   return @"iPhone 5C";
if ([phoneModel isEqualToString:@"iPhone6,1"] ||
    [phoneModel isEqualToString:@"iPhone6,2"])   return @"iPhone 5S";
if ([phoneModel isEqualToString:@"iPhone7,1"]) return @"iPhone 6 Plus";
if ([phoneModel isEqualToString:@"iPhone7,2"]) return @"iPhone 6";
if ([phoneModel isEqualToString:@"iPhone8,1"]) return @"iPhone 6s";
if ([phoneModel isEqualToString:@"iPhone8,2"]) return @"iPhone 6s Plus";
if ([phoneModel isEqualToString:@"iPhone8,4"]) return @"iPhone SE";
if ([phoneModel isEqualToString:@"iPhone9,1"]) return @"iPhone 7";
if ([phoneModel isEqualToString:@"iPhone9,2"]) return @"iPhone 7 Plus";
if ([phoneModel isEqualToString:@"iPhone10,1"] ||
    [phoneModel isEqualToString:@"iPhone10,4"]) return @"iPhone 8";
if ([phoneModel isEqualToString:@"iPhone10,2"] ||
    [phoneModel isEqualToString:@"iPhone10,5"]) return @"iPhone 8 Plus";
if ([phoneModel isEqualToString:@"iPhone10,3"] ||
    [phoneModel isEqualToString:@"iPhone10,6"]) return @"iPhone X";

if([phoneModel isEqualToString:@"iPhone11,8"]) return @"iPhone XR";

if([phoneModel isEqualToString:@"iPhone11,2"]) return @"iPhone XS";

if([phoneModel isEqualToString:@"iPhone11,6"]) return @"iPhone XS Max";




if ([phoneModel isEqualToString:@"iPad1,1"]) return @"iPad";
if ([phoneModel isEqualToString:@"iPad2,1"] ||
    [phoneModel isEqualToString:@"iPad2,2"] ||
    [phoneModel isEqualToString:@"iPad2,3"] ||
    [phoneModel isEqualToString:@"iPad2,4"]) return @"iPad 2";
if ([phoneModel isEqualToString:@"iPad3,1"] ||
    [phoneModel isEqualToString:@"iPad3,2"] ||
    [phoneModel isEqualToString:@"iPad3,3"]) return @"iPad 3";
if ([phoneModel isEqualToString:@"iPad3,4"] ||
    [phoneModel isEqualToString:@"iPad3,5"] ||
    [phoneModel isEqualToString:@"iPad3,6"]) return @"iPad 4";
if ([phoneModel isEqualToString:@"iPad4,1"] ||
    [phoneModel isEqualToString:@"iPad4,2"] ||
    [phoneModel isEqualToString:@"iPad4,3"]) return @"iPad Air";
if ([phoneModel isEqualToString:@"iPad5,3"] ||
    [phoneModel isEqualToString:@"iPad5,4"]) return @"iPad Air 2";
if ([phoneModel isEqualToString:@"iPad6,3"] ||
    [phoneModel isEqualToString:@"iPad6,4"]) return @"iPad Pro 9.7-inch";
if ([phoneModel isEqualToString:@"iPad6,7"] ||
    [phoneModel isEqualToString:@"iPad6,8"]) return @"iPad Pro 12.9-inch";
if ([phoneModel isEqualToString:@"iPad6,11"] ||
    [phoneModel isEqualToString:@"iPad6,12"]) return @"iPad 5";
if ([phoneModel isEqualToString:@"iPad7,1"] ||
    [phoneModel isEqualToString:@"iPad7,2"]) return @"iPad Pro 12.9-inch 2";
if ([phoneModel isEqualToString:@"iPad7,3"] ||
    [phoneModel isEqualToString:@"iPad7,4"]) return @"iPad Pro 10.5-inch";

if ([phoneModel isEqualToString:@"iPad2,5"] ||
    [phoneModel isEqualToString:@"iPad2,6"] ||
    [phoneModel isEqualToString:@"iPad2,7"]) return @"iPad mini";
if ([phoneModel isEqualToString:@"iPad4,4"] ||
    [phoneModel isEqualToString:@"iPad4,5"] ||
    [phoneModel isEqualToString:@"iPad4,6"]) return @"iPad mini 2";
if ([phoneModel isEqualToString:@"iPad4,7"] ||
    [phoneModel isEqualToString:@"iPad4,8"] ||
    [phoneModel isEqualToString:@"iPad4,9"]) return @"iPad mini 3";
if ([phoneModel isEqualToString:@"iPad5,1"] ||
    [phoneModel isEqualToString:@"iPad5,2"]) return @"iPad mini 4";

if ([phoneModel isEqualToString:@"iPod1,1"]) return @"iTouch";
if ([phoneModel isEqualToString:@"iPod2,1"]) return @"iTouch2";
if ([phoneModel isEqualToString:@"iPod3,1"]) return @"iTouch3";
if ([phoneModel isEqualToString:@"iPod4,1"]) return @"iTouch4";
if ([phoneModel isEqualToString:@"iPod5,1"]) return @"iTouch5";
if ([phoneModel isEqualToString:@"iPod7,1"]) return @"iTouch6";

if ([phoneModel isEqualToString:@"i386"] || [phoneModel isEqualToString:@"x86_64"]) return @"iPhone Simulator";

return @"Unknown";
}

4.这样就能拿到设备号了，但是太麻烦了，出新手机又要适配，麻烦，个人建议直接拿 machine 信息就好，再去网上对照。

struct utsname systemInfo;
uname(&systemInfo);
NSString *model = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];
