app中总会用到客户端下载量数据统计,一般都是用的设备的唯一码作为标示,以下是获取mac地址的代码片段,记录备份。
android 获取mac地址
1. <uses-permission android:name="android.permission.ACCESS_WIFI_STATE">
2. private String getLocalMacAddress(){
WifiManager wifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo info = wifi.getConnectionInfo();
return info.getMacAddress();
}
android 获取IMEI数据
public static String getIMEI(Context context) {
return ((TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();
}
ios 获得mac地址
+(NSString *)getLocalMacAddress
{
int mib[6];
size_t len;
char *buf;
unsigned char *ptr;
struct if_msghdr *ifm;
struct sockaddr_dl *sdl;
mib[0] = CTL_NET;
mib[1] = AF_ROUTE;
mib[2] = 0;
mib[3] = AF_LINK;
mib[4] = NET_RT_IFLIST;
if ((mib[5] = if_nametoindex("en0")) == 0) {
//printf("Error: if_nametoindex error/n");
return NULL;
}
if (sysctl(mib, 6, NULL, &len, NULL, 0) < 0) {
//printf("Error: sysctl, take 1/n");
return NULL;
}
if ((buf = malloc(len)) == NULL) {
//printf("Could not allocate memory. error!/n");
return NULL;
}
if (sysctl(mib, 6, buf, &len, NULL, 0) < 0) {
//printf("Error: sysctl, take 2");
return NULL;
}
ifm = (struct if_msghdr *)buf;
sdl = (struct sockaddr_dl *)(ifm + 1);
ptr = (unsigned char *)LLADDR(sdl);
// NSString *outstring = [NSString stringWithFormat:@"%02x:%02x:%02x:%02x:%02x:%02x", *ptr, *(ptr+1), *(ptr+2), *(ptr+3), *(ptr+4), *(ptr+5)];

free(buf);
return [outstring uppercaseString];

在这儿有两个概念UUID与UDID.
UUID是Universally Unique Identifier 通用唯一标识码
UDID是Unique Device Identifier 设备唯一标识码
UDID只是UUID的一个子集而已。
- -(NSString*)uuid
- {
- CFUUIDRef puuid = CFUUIDCreate( nil );
- CFStringRef uuidString = CFUUIDCreateString( nil, puuid );
- NSString * result = (NSString *)CFStringCreateCopy( NULL, uuidString);
- CFRelease(puuid);
- CFRelease(uuidString);
- return [result autorelease];
- }
- (NSString *)uuid
{
CFUUIDReftheUUID = CFUUIDCreate(NULL);
CFStringRefstring = CFUUIDCreateString(NULL, theUUID);
NSMakeCollectable(theUUID);
return(NSString *)string;
