Question

我想找出所有点击我广告的移动设备列表。基于我想重新定位的细节

所以我需要捕获他们的标识符（ios中的UDID和android手机中的Android id）以识别它们。

任何人都可以建议我使用好的方法或者更喜欢任何更好的方法来实现上述目标。

Answer 1

对于Android，你应该检查这个帖子：

Will TelephonyManger.getDeviceId() return device id for Tablets like Galaxy Tab...?

Jorgesys的回答似乎很干净。

Answer 2

ANDROID：我正在使用它，似乎工作正常。

public static String getDeviceAndroidID(Context context)
{
    String android_id = Secure.getString(context.getContentResolver(), Secure.ANDROID_ID);
    if(android_id != null)
        return android_id;
    else
        return "";
}

的iOS：对于小于7的iOS版本，我使用的是设备的MAC地址。从iOS版本7开始，apple为此提供了一个唯一的ID。

(NSString *)getMacAddress
{
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
{
    NSString *strUID = nil;
    if(strUID == nil) strUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    return strUID;
}


int                 mgmtInfoBase[6];
char                *msgBuffer = NULL;
size_t              length;
unsigned char       macAddress[6];
struct if_msghdr    *interfaceMsgStruct;
struct sockaddr_dl  *socketStruct;
NSString            *errorFlag = nil;


// Setup the management Information Base (mib)
mgmtInfoBase[0] = CTL_NET;        // Request network subsystem
mgmtInfoBase[1] = AF_ROUTE;       // Routing table info
mgmtInfoBase[2] = 0;
mgmtInfoBase[3] = AF_LINK;        // Request link layer information
mgmtInfoBase[4] = NET_RT_IFLIST;  // Request all configured interfaces


// With all configured interfaces requested, get handle index
if ((mgmtInfoBase[5] = if_nametoindex("en0")) == 0)
    errorFlag = @"if_nametoindex failure";
else
{
    // Get the size of the data available (store in len)
    if (sysctl(mgmtInfoBase, 6, NULL, &length, NULL, 0) < 0)
        errorFlag = @"sysctl mgmtInfoBase failure";
    else
    {
        // Alloc memory based on above call
        if ((msgBuffer = malloc(length)) == NULL)
            errorFlag = @"buffer allocation failure";
        else
        {
            // Get system information, store in buffer
            if (sysctl(mgmtInfoBase, 6, msgBuffer, &length, NULL, 0) < 0)
                errorFlag = @"sysctl msgBuffer failure";
        }
    }
}
// Befor going any further...
if (errorFlag != nil)
{
    free(msgBuffer);
    if(ENABLE_LOG) DLog(@"Error: %@", errorFlag);
    return errorFlag;
}
// Map msgbuffer to interface message structure
interfaceMsgStruct = (struct if_msghdr *) msgBuffer;
// Map to link-level socket structure
socketStruct = (struct sockaddr_dl *) (interfaceMsgStruct + 1);
// Copy link layer address data in socket structure to an array
memcpy(&macAddress, socketStruct->sdl_data + socketStruct->sdl_nlen, 6);
// Read from char array into a string object, into traditional Mac address format
NSString *macAddressString = [NSString stringWithFormat:@"%02X:%02X:%02X:%02X:%02X:%02X",
                              macAddress[0], macAddress[1], macAddress[2],
                              macAddress[3], macAddress[4], macAddress[5]];
//if(ENABLE_LOG) DLog(@"Mac Address: %@", macAddressString);  
// Release the buffer memory
free(msgBuffer);
return macAddressString;
}

查找移动设备标识符（UDID或Android ID）
