Here is a common method of retriving the device model. There are no NS methods for this, so you gotta use c

#include 
#include 

- (NSString *)machine {
    NSString *machine;
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *name = malloc(size);
    sysctlbyname("hw.machine", name, &size, NULL, 0);
    machine = [NSString stringWithUTF8String:name];
    free(name);
    return machine;
}
