iPhone 数据使用跟踪/监控 [英] iPhone Data Usage Tracking/Monitoring
问题描述
我搜索了这个主题，但发现有用的细节很少.根据这些细节，我尝试编写如下代码.
注意:在将此帖子标记为重复之前，请将此帖子中共享的详细信息与其他帖子进行比较，而不仅仅是按主题.
- (NSArray *)getDataCountersForType:(int)type {布尔成功；结构 ifaddrs *addrs = nil;const struct ifaddrs *cursor = nil;const struct sockaddr_dl *dlAddr = nil;const struct if_data *networkStatisc = nil;int dataSent = 0;int dataReceived = 0;成功 = getifaddrs(&addrs) == 0;如果(成功){游标 = 地址；而(光标！= NULL){如果(光标->ifa_addr->sa_family == AF_LINK){dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;networkStatisc = (const struct if_data *) cursor->ifa_data;如果(类型== WiFi){dataSent += networkStatisc->ifi_opackets;dataReceived += networkStatisc->ifi_ipackets;}否则如果(类型== WWAN){dataSent += networkStatisc->ifi_obytes;dataReceived += networkStatisc->ifi_ibytes;}}cursor = cursor->ifa_next;}freeifaddrs(地址)；}返回 [NSArray arrayWithObjects:[NSNumber numberWithInt:dataSent], [NSNumber numberWithInt:dataReceived], nil];}此代码收集 iPhone 设备(而不是我的应用程序)的互联网使用信息.
现在，如果我通过 WiFi 或 3G 使用互联网，我只能在 ifi_obytes(发送)和 ifi_ibytes(接收)中获取数据(字节)，但我认为我应该在 ifi_opackets 和 ifi_ipackets 中使用 WiFi.
还想补充一点，如果我已连接到 WiFi 网络，但不使用互联网，我仍然可以为 ifi_obytes 和 ifi_ibytes 添加价值.
可能是我在实施或理解上有误.需要有人帮助我.
<小时>我尝试了 AF_INET(sockaddr_in 而不是 sockaddr_dl)而不是 AF_LINK.这会导致应用程序崩溃.
pdp_ip0是接口之一，所有pdpXXX都是WWAN代码>专用于不同功能的接口、语音邮件、通用网络接口.
我在苹果论坛上读到:操作系统不会逐个进程地保留网络统计信息.因此，这个问题没有确切的解决方案.但是，您可以获取每个网络接口的网络统计信息.
一般来说，en0 是您的 Wi-Fi 接口，pdp_ip0 是您的 WWAN 接口.
没有什么好方法可以获取信息 wifi/蜂窝网络数据，因为特定的日期时间！
数据统计信息(ifa_data->ifi_obytes 和 ifa_data->ifi_ibytes)是从之前的设备重启中存储的.
我不知道为什么，但是 ifi_opackets 和 ifi_ipackets 仅针对 lo0 显示(我认为是它的主界面).
是的.然后设备通过 WiFi 连接并且不使用互联网 if_iobytes 值仍然存在，因为此方法提供网络字节交换而不仅仅是互联网.

I've searched over this topic but found very few details which were helpful. With these details I've tried to cook some code as follows.
Note: Please compare the details shared in this post with other posts before marking this as DUPLICATE, and not just by the subject.
- (NSArray *)getDataCountersForType:(int)type {
BOOL success;
struct ifaddrs *addrs = nil;
const struct ifaddrs *cursor = nil;
const struct sockaddr_dl *dlAddr = nil;
const struct if_data *networkStatisc = nil;
int dataSent = 0;
int dataReceived = 0;
success = getifaddrs(&addrs) == 0;
if (success) {
cursor = addrs;
while (cursor != NULL) {
if (cursor->ifa_addr->sa_family == AF_LINK) {
dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
networkStatisc = (const struct if_data *) cursor->ifa_data;
if (type == WiFi) {
dataSent += networkStatisc->ifi_opackets;
dataReceived += networkStatisc->ifi_ipackets;
}
else if (type == WWAN) {
dataSent += networkStatisc->ifi_obytes;
dataReceived += networkStatisc->ifi_ibytes;
}
}
cursor = cursor->ifa_next;
}
freeifaddrs(addrs);
}
return [NSArray arrayWithObjects:[NSNumber numberWithInt:dataSent], [NSNumber numberWithInt:dataReceived], nil];
}
This code collects information of internet usage of an iPhone device (and not my application alone).
Now, if I use internet through WiFi or through 3G, I get the the data (bytes) only in ifi_obytes (sent) and ifi_ibytes (received) but I think I should get WiFi usage in ifi_opackets and ifi_ipackets.
Also wanted to add that if I'm connected to a WiFi network, but am not using internet, I still get value added to ifi_obytes and ifi_ibytes.
May be I'm wrong in the implementation or understanding. Need someone to help me out.
Edit: Instead of AF_LINK I tried AF_INET (sockaddr_in instead of sockaddr_dl). This crashes the application.
The thing is that pdp_ip0 is one of interfaces, all pdpXXX are WWAN interfaces dedicated to different functions, voicemail, general networking interface.
I read in Apple forum that : The OS does not keep network statistics on a process-by-process basis. As such, there's no exact solution to this problem. You can, however, get network statistics for each network interface.
In general en0 is your Wi-Fi interface and pdp_ip0 is your WWAN interface.
There is no good way to get information wifi/cellular network data since, particular date-time!
Data statistic (ifa_data->ifi_obytes and ifa_data->ifi_ibytes) are stored from previous device reboot.
I don't know why, but ifi_opackets and ifi_ipackets are shown just for lo0 (I think its main interface ).
Yes. Then device is connected via WiFi and doesn't use internet if_iobytes values still come because this method provides network bytes exchanges and not just internet.
