1、获取设备的常用信息

NSLog(@"name: %@", [[UIDevice currentDevice] name]);
NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
NSLog(@"model: %@", [[UIDevice currentDevice] model]);
NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

name: i6+
systemName: iPhone OS
systemVersion: 9.1
model:iPhone
localizedModel: iPhone

2、如果要获取手机具体型号

include <sys/sysctl.h>

//获得设备型号

+ (NSString *)GetCurrentDeviceModel

{

int mib[2];

size_t len;

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 = [NSString stringWithCString:machineencoding:NSASCIIStringEncoding];

free(machine);
