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，但发现很少有些有用的细节。根据这些细节，我尝试按如下方式编写一些代码。
注意：请将此帖中分享的详细信息与其他帖子进行比较，然后再将其标记为DUPLICATE ，而不仅仅是主题。
- （NSArray *）getDataCountersForType：（int）type {
BOOL成功;
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];
}
此代码收集iPhone设备的互联网使用信息（而不是我的应用程序）单独）。
现在，如果我通过WiFi或通过3G使用互联网，我只能在 ifi_obytes （已发送）和。 ifi_ibytes （收到）但我认为我应该在 ifi_opackets 和<$ c $中获得WiFi使用c> ifi_ipackets
还想补充一点，如果我连接到WiFi网络，但我没有使用互联网，我仍然会得到值已添加到 ifi_obytes 和 ifi_ibytes 。
可能是我在实施或理解上错了。需要有人帮助我。
编辑：而不是 AF_LINK 我尝试了 AF_INET （ sockaddr_in 而不是 sockaddr_dl ）。这会使应用程序崩溃。
问题是pdp_ip0是接口之一，所有pdpXXX都是专用于不同功能的WWAN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行网络统计。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。
通常，en0是您的Wi-Fi接口，pdp_ip0是您的WWAN接口。
因为特定的日期时间，没有好的方法来获取信息wifi /蜂窝网络数据！
数据统计（ifa_data-> ifi_obytes和ifa_data-> ifi_ibytes）存储在之前的设备重启中。
我不知道为什么，但ifi_opackets和ifi_ipackets只显示为lo0（我认为它的主界面）。
是的。然后设备通过WiFi连接，不使用互联网if_iobytes值仍然来，因为这种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 .
