检测特定的 iPhone/iPod touch 模型

可能的复制品:
用 iOS 确定设备(iPhone，iPod Touch)

我正在做一个游戏，利用点对点的蓝牙功能的 iPhone (可能是 iPod touch 第二代)。然而，为了阻止用户在 iPod 1和 iPhone 2G 上玩多人游戏，我需要检查一下具体的设备型号。

[[ UIDevicecurrentDevice ]模型]只能告诉我这个设备是“ iPhone”还是“ iPod touch”。有没有一种方法来检查特定的设备型号，比如: “ iPhone3GS”，“ iPod touch 第一代”或者其他什么。

编辑:

UIDdevice 有一个分类(我认为它是由 Erica Sadun 创建的，我不会为此居功) ，它使用以下代码来获得特定的设备模型。您可以在这里找到整个类别以及其他有用的东西: https://github.com/erica/uidevice-extension

#include <sys/types.h>
#include <sys/sysctl.h>


@implementation UIDevice (Hardware)


/*
Platforms
iPhone1,1 -> iPhone 1G
iPhone1,2 -> iPhone 3G
iPod1,1   -> iPod touch 1G
iPod2,1   -> iPod touch 2G
*/


- (NSString *) platform
{
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *machine = malloc(size);
sysctlbyname("hw.machine", machine, &size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);
return platform;
}

这个工具和使用它的应用程序最近在 AppStore 中得到了批准。

You can get the device model number using uname from sys/utsname.h. For example:

#import <sys/utsname.h>


NSString*
machineName()
{
struct utsname systemInfo;
uname(&systemInfo);


return [NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding];
}

The result should be: 

@"i386"      on the simulator
@"iPod1,1"   on iPod Touch
@"iPod2,1"   on iPod Touch Second Generation
@"iPod3,1"   on iPod Touch Third Generation
@"iPod4,1"   on iPod Touch Fourth Generation
@"iPhone1,1" on iPhone
@"iPhone1,2" on iPhone 3G
@"iPhone2,1" on iPhone 3GS
@"iPad1,1"   on iPad
@"iPad2,1"   on iPad 2
@"iPad3,1"   on iPad 3 (aka new iPad)
@"iPhone3,1" on iPhone 4
@"iPhone4,1" on iPhone 4S
@"iPhone5,1" on iPhone 5
@"iPhone5,2" on iPhone 5

Most complete UIDevice (Hardware) category probably is http://github.com/erica/uidevice-extension/ (by Erica Sadun):

[[UIDevice currentDevice] platformType]   // ex: UIDevice4GiPhone
[[UIDevice currentDevice] platformString] // ex: @"iPhone 4G"

BOOL hasHighResScreen = NO;
if ([UIScreen instancesRespondToSelector:@selector(scale)]) {
CGFloat scale = [[UIScreen mainScreen] scale];
if (scale > 1.0) {
hasHighResScreen = YES;
}
}
小开 
NSString* valueDevice = [[UIDevice currentDevice] model];

and then check if the string is equal to whatever device you are looking for like :

if(value==@"iPod1,1" )
{}

and you should be good to go

iPhone 4 is iPhone3,1 and iPhone3,2
iPhone 4S is iPhone4,1
iPad 2 is iPad2,1 iPad2,2 and iPad2,3 depending on version (GSM etc)
iPad 3 is iPad3,1 iPad3,2 and iPad3,3 depending on version (GSM etc)

See Iphone secrets (scroll down to "internal product codes")

How about this code, if new version was released, you will identifier with the last know device

#include <sys/types.h>
#include <sys/sysctl.h>


- (NSString *)getModel {
size_t size;
sysctlbyname("hw.machine", NULL, &size, NULL, 0);
char *model = malloc(size);
sysctlbyname("hw.machine", model, &size, NULL, 0);
NSString *sDeviceModel = [NSString stringWithCString:model encoding:NSUTF8StringEncoding];
free(model);
if ([sDeviceModel isEqual:@"i386"])      return @"Simulator";  //iPhone Simulator
if ([sDeviceModel isEqual:@"iPhone1,1"]) return @"iPhone1G";   //iPhone 1G
if ([sDeviceModel isEqual:@"iPhone1,2"]) return @"iPhone3G";   //iPhone 3G
if ([sDeviceModel isEqual:@"iPhone2,1"]) return @"iPhone3GS";  //iPhone 3GS
if ([sDeviceModel isEqual:@"iPhone3,1"]) return @"iPhone4 AT&T";  //iPhone 4 - AT&T
if ([sDeviceModel isEqual:@"iPhone3,2"]) return @"iPhone4 Other";  //iPhone 4 - Other carrier
if ([sDeviceModel isEqual:@"iPhone3,3"]) return @"iPhone4";    //iPhone 4 - Other carrier
if ([sDeviceModel isEqual:@"iPhone4,1"]) return @"iPhone4S";   //iPhone 4S
if ([sDeviceModel isEqual:@"iPhone5,1"]) return @"iPhone5";    //iPhone 5 (GSM)
if ([sDeviceModel isEqual:@"iPod1,1"])   return @"iPod1stGen"; //iPod Touch 1G
if ([sDeviceModel isEqual:@"iPod2,1"])   return @"iPod2ndGen"; //iPod Touch 2G
if ([sDeviceModel isEqual:@"iPod3,1"])   return @"iPod3rdGen"; //iPod Touch 3G
if ([sDeviceModel isEqual:@"iPod4,1"])   return @"iPod4thGen"; //iPod Touch 4G
if ([sDeviceModel isEqual:@"iPad1,1"])   return @"iPadWiFi";   //iPad Wifi
if ([sDeviceModel isEqual:@"iPad1,2"])   return @"iPad3G";     //iPad 3G
if ([sDeviceModel isEqual:@"iPad2,1"])   return @"iPad2";      //iPad 2 (WiFi)
if ([sDeviceModel isEqual:@"iPad2,2"])   return @"iPad2";      //iPad 2 (GSM)
if ([sDeviceModel isEqual:@"iPad2,3"])   return @"iPad2";      //iPad 2 (CDMA)


NSString *aux = [[sDeviceModel componentsSeparatedByString:@","] objectAtIndex:0];


//If a newer version exist
if ([aux rangeOfString:@"iPhone"].location!=NSNotFound) {
int version = [[aux stringByReplacingOccurrencesOfString:@"iPhone" withString:@""] intValue];
if (version == 3) return @"iPhone4"
if (version >= 4) return @"iPhone4s";


}
if ([aux rangeOfString:@"iPod"].location!=NSNotFound) {
int version = [[aux stringByReplacingOccurrencesOfString:@"iPod" withString:@""] intValue];
if (version >=4) return @"iPod4thGen";
}
if ([aux rangeOfString:@"iPad"].location!=NSNotFound) {
int version = [[aux stringByReplacingOccurrencesOfString:@"iPad" withString:@""] intValue];
if (version ==1) return @"iPad3G";
if (version >=2) return @"iPad2";
}
//If none was found, send the original string
return sDeviceModel;
}
