如何获取ios设备型号

首先导入头文件  #import "sys/utsname.h"

struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

if ([deviceString isEqualToString:@"iPhone3,1"])    return @"iPhone 4";

if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";

if ([deviceString isEqualToString:@"iPhone5,1"] || [deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5";

if ([deviceString isEqualToString:@"iPhone5,3"] || [deviceString isEqualToString:@"iPhone5,4"])    return @"iPhone 5C";

if ([deviceString isEqualToString:@"iPhone6,1"] || [deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5S";

if ([deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5S";
if ([deviceString isEqualToString:@"iPhone7,1"])    return @"iPhone 6 Plus";
if ([deviceString isEqualToString:@"iPhone7,2"])    return @"iPhone 6";
if ([deviceString isEqualToString:@"iPhone8,1"])    return @"iPhone 6s";
if ([deviceString isEqualToString:@"iPhone8,2"])    return @"iPhone 6s Plus";

if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";
if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";
if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";
if ([deviceString isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";
if ([deviceString isEqualToString:@"iPad2,4"])      return @"iPad 2 (32nm)";
if ([deviceString isEqualToString:@"iPad2,5"])      return @"iPad mini (WiFi)";
if ([deviceString isEqualToString:@"iPad2,6"])      return @"iPad mini (GSM)";
if ([deviceString isEqualToString:@"iPad2,7"])      return @"iPad mini (CDMA)";

if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3(WiFi)";
if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3(CDMA)";
if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3(4G)";
if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4 (4G)";
if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (CDMA)";

if ([deviceString isEqualToString:@"iPad4,1"])      return @"iPad Air";
if ([deviceString isEqualToString:@"iPad4,2"])      return @"iPad Air";
if ([deviceString isEqualToString:@"iPad4,3"])      return @"iPad Air";
if ([deviceString isEqualToString:@"iPad5,3"])      return @"iPad Air 2";
if ([deviceString isEqualToString:@"iPad5,4"])      return @"iPad Air 2";
if ([deviceString isEqualToString:@"i386"])         return @"Simulator";
if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";

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