Determine device (iPhone, iPod Touch) with iOS
I am making a game that utilizes the peer-to-peer bluetooth capabilities of the iPhone (and probably the iPod touch 2nd generation). However, to stop the users from trying to play a multiplayer on an iPod 1st gen and iPhone 2G I need to check for the specific device model.
[[UIDevice currentDevice] model] will only tell me if the device is an \"iPhone\" or an \"iPod touch\". Is there a way to check for the specific device model, like: \"iPhone 3GS\", \"iPod touch 1st generation\" or something.
EDIT:
There is a category to UIDevice (I think it\'s created by Erica Sadun, I don\'t take credit for it) that uses the following code to get the specific device model. You can find the whole category here along with other useful stuff: 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;
}
This works and apps using this have been lately approved in the AppStore.

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"

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

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;
}

BOOL hasHighResScreen = NO;
if ([UIScreen instancesRespondToSelector:@selector(scale)]) {
CGFloat scale = [[UIScreen mainScreen] scale];
if (scale > 1.0) {
hasHighResScreen = YES;
}
}
回答5:
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")

回答6:
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
