IOS gets the current Apple device model (true machine test is valid, the simulator only outputs display simulator)

IOS get current Apple device model code:

-(nsstring*) Dodeviceplatform
{
size_t size;

int NR = Sysctlbyname ("Hw.machine", NULL, &size, null,0);

Char*machine = (char*) malloc (size);
NR = Sysctlbyname ("Hw.machine", Machine, &size,null, 0);

NSString *platform = [NSString stringwithcstring:machine encoding:nsutf8stringencoding];

Free (machine);
