如何判断iOS设备硬件型号

方法1：

#include <sys/sysctl.h>

- (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 = [NSStringstringWithCString:machineencoding:NSUTF8StringEncoding];  
    free(machine);  
    return platform;  
}

方法2：

#import <sys/utsname.h>

NSString*machineName()

{

struct utsname systemInfo;

uname(&systemInfo);

return [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];

}

逗号后面数字解释：(i386是指模拟器)
