我正在寻找完成/维护此方法的最官方来源：
-(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];
}
Apple在某个地方有这方面的陈述吗？
或者是一个在某个地方进行过体面研究的骄傲的人？
澄清，我正在使用此代码：
-(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"]; }

到目前为止，我发现了一些非官方消息来源：
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
仍在寻找更官方的消息来源。
刚从iPhone Wiki中提取（直到iPhone 5S，iPad Air）：

它现在是eppz!kit on GitHub的一部分以及其余的代码。在EPPZDevice.h类中实现。

iOS设备要求关注Apple页面以获取更新包：
此XML包含“SupportedDevices”键，其标识符值为“iPhone6,1”，“iPhone5,3”。 “模型”键印在iOS设备的背面，或者您可以在苹果网页上找到它们，例如：
http://www.apple.com/legal/rfexposure/iphone5,4/cs/
Apple也在使用所有型号更新其支持页面： http://support.apple.com/kb/ht3939
