1.在用到的地方导入头文件：#include <sys/sysctl.h>

2.将该方法粘贴到对应地方 ，调用即可：

- (NSString*)getCurrentDeviceModel:(UIViewController*)controller

{

intmib[2];

size_tlen;

char*machine;

mib[0] =CTL_HW;

mib[1] =HW_MACHINE;

sysctl(mib,2,NULL, &len,NULL,0);

machine =malloc(len);

sysctl(mib,2, machine, &len,NULL,0);

NSString*platform = [NSStringstringWithCString:machineencoding:NSASCIIStringEncoding];

free(machine);
