问题
I'm looking for the most official source to complete/maintain this method:
-(NSString*)platformString
{
NSString *platform = [self platform];
if ([platform isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";
if ([platform isEqualToString:@"iPhone1,2"]) return @"iPhone 3G";
if ([platform isEqualToString:@"iPhone2,1"]) return @"iPhone 3GS";
if ([platform isEqualToString:@"iPhone3,1"]) return @"iPhone 4";
if ([platform isEqualToString:@"iPhone3,2"]) return @"iPhone 4 (Other Carrier)";
if ([platform isEqualToString:@"iPhone3,3"]) return @"iPhone 4 CDMA";
if ([platform isEqualToString:@"iPhone4,1"]) return @"iPhone 4S";
if ([platform isEqualToString:@"iPhone5,1"]) return @"iPhone 5";
if ([platform isEqualToString:@"iPod1,1"]) return @"iPod Touch 1G";
if ([platform isEqualToString:@"iPod2,1"]) return @"iPod Touch 2G";
if ([platform isEqualToString:@"iPod3,1"]) return @"iPod Touch 3G";
if ([platform isEqualToString:@"iPod4,1"]) return @"iPod Touch 4G";
if ([platform isEqualToString:@"iPod5,1"]) return @"iPod Touch 5G";
if ([platform isEqualToString:@"iPad1,1"]) return @"iPad";
if ([platform isEqualToString:@"iPad2,1"]) return @"iPad 2 WiFi";
if ([platform isEqualToString:@"iPad2,2"]) return @"iPad 2 GSM";
if ([platform isEqualToString:@"iPad2,3"]) return @"iPad 2 CDMA";
if ([platform isEqualToString:@"iPad2,4"]) return @"iPad 2 CDMAS";
if ([platform isEqualToString:@"iPad2,5"]) return @"iPad Mini Wifi";
if ([platform isEqualToString:@"iPad2,6"]) return @"iPad mini (Cellular ATT)";
if ([platform isEqualToString:@"iPad2,7"]) return @"iPad mini (Cellular Verizon)";
if ([platform isEqualToString:@"iPad3,1"]) return @"iPad 3 WiFi";
if ([platform isEqualToString:@"iPad3,2"]) return @"iPad 3 CDMA";
if ([platform isEqualToString:@"iPad3,3"]) return @"iPad 3 GSM";
if ([platform isEqualToString:@"iPad3,4"]) return @"iPad 4 Wifi";
if ([platform isEqualToString:@"iPad3,5"]) return @"iPad 3 (Cellular ATT)";
if ([platform isEqualToString:@"iPad3,6"]) return @"iPad 3 (Cellular Verizon)";
if ([platform isEqualToString:@"iPad4,1"]) return @"iPad 4 WiFi";
if ([platform isEqualToString:@"iPad4,2"]) return @"iPad 4 GSM";
if ([platform isEqualToString:@"iPad4,3"]) return @"iPad 4 CDMA";
if ([platform isEqualToString:@"i386"]) return @"Simulator";
if ([platform isEqualToString:@"x86_64"]) return @"Simulator";
return [NSString stringWithFormat:@"Unknown: %@", platform];
}
Does Apple have some statement about this somewhere?
Or an explorous person with a decent research somewhere?
Fo clarification, I'm using this code under the hood:
-(NSString*)getSysInfoByName:(char*) typeSpecifier
{
size_t size;
sysctlbyname(typeSpecifier, NULL, &size, NULL, 0);
char *answer = malloc(size);
sysctlbyname(typeSpecifier, answer, &size, NULL, 0);
NSString *results = [NSString stringWithCString:answer encoding: NSUTF8StringEncoding];
free(answer);
return results;
}
-(NSString*)platform
{ return [self getSysInfoByName:"hw.machine"]; }

Some non-official source I've found so far:
Models - The iPhone Wiki
iClarified - iPhone - Where To Download iPhone Firmware Files From
iClarified - iPad - Where To Download iPad Firmware Files From
iClarified - iPod touch - Where to Download iPod touch Firmware Files From
Still looking for a more official source, though.
Just extracted from iPhone Wiki (up till iPhone 5S, iPad Air):

It is now part of eppz!kit on GitHub along with the rest of the code. Implemented in EPPZDevice.h class.

iOS devices are asking following Apple page for update packages:
http://mesu.apple.com/assets/com_apple_MobileAsset_SoftwareUpdate/com_apple_MobileAsset_SoftwareUpdate.xml
This XML contains "SupportedDevices" key with identifier values like "iPhone6,1", "iPhone5,3". "Model" key is printed on the back side of the iOS device or you can find them on apple webpages e.g.:
http://www.apple.com/legal/rfexposure/iphone5,4/cs/
Apple is also updating its support page with all models: http://support.apple.com/kb/ht3939
