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.

Answer 1

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"

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;
}

Answer 4

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

Answer 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)

Answer 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
