iPhone 数据使用跟踪/监控

我已经搜索了这个主题，但发现很少有帮助的细节。有了这些细节，我尝试编写一些代码如下。

注意：在将其标记为重复之前，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 {
    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];    
}

此代码收集 iPhone 设备的互联网使用信息（而不仅仅是我的应用程序）。

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）中获得数据（字节），但我认为我应该在 ifi_opackets 和 {4 中获得 WiFi 使用情况}。

还想补充一点，如果我连接到 WiFi 网络，但没有使用互联网，我仍然可以为 ifi_obytes 和 ifi_ibytes 增值。

可能是我在实施或理解上错了。需要有人帮助我。

编辑：我尝试了 AF_INET 而不是 AF_LINK（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 Apple 论坛上读到：操作系统不会按进程保存网络统计信息。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。

通常，en0 是您的 Wi-Fi 界面，而 pdp_ip0 是您的 WWAN 界面。

由于特定的日期时间，没有很好的方法来获取信息 wifi/蜂窝网络数据！

数据统计信息（ifa_data->ifi_obytes 和 ifa_data->ifi_ibytes）是从上次设备重新启动时存储的。

我不知道为什么，但 ifi_opackets 和 ifi_ipackets 仅针对 lo0 显示（我认为它的主界面）。

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。

非常感谢。这段代码创造了奇迹。也感谢您解释这些东西。
你需要导入这个库：#include #include #include #include
是否可以使用此代码跟踪每个 iOS 应用程序的数据流量？
@Mat：我为企业客户设计的解决方案没有部署在 AppStore 上。
有人知道如何获取每个应用程序的数据吗？请分享代码:)

重要的是要了解这些计数器是自设备上次启动以来提供的。

因此，为了有效地利用它们，您应该为每个样本提供设备的正常运行时间（您可以使用 mach_absolute_time() - 请参阅 this 了解更多信息）

一旦你有了计数器样本+正常运行时间，你就可以对数据使用有更好的启发......

mach_absolute_time 不是正常运行时间。这大致是 CPU 处于活动状态的时间量。 mach_absolute_time 大多在设备休眠时停止计数。

要添加到已接受的答案，重要的是要意识到界面显示的数据量在每个 4 GB 之后溢出并在 0 处重新启动，特别是如果您使用此代码计算两个读数之间的差异。这是因为 ifi_obytes 和 ifi_ibytes 是 uint_32 并且它们的最大值是 4294967295。

此外，我建议对包含发送和接收数据的变量使用 unsigned int。正则 int 的最大值是无符号整数的一半，所以在加上 ifi_obytes 时，可能会导致溢出。 

unsigned int sent = 0;
sent += networkStatisc->ifi_obytes;

我将上面的源代码修复为 Swift3 版本

基于以前版本的新版本，但适用于 Swift4 和 Xcode 9

它是否显示每个应用程序或使用它的实际应用程序？
这是全球使用......它没有被应用程序分开。
该值来自上次重新启动。无法获得过去/当前月份的数据？
@斯拉夫乔。在此发布日期之前，这是不可能的。 iOS12之后我还没有对它进行新的研究。我建议你在某个地方积累 ir 以在之后恢复它。

再次抱歉相同的答案。

但是我发现 UInt32 不够用，所以当它变得太大时它会崩溃。

我刚刚将 UInt32 更改为 UInt64，它工作正常。 

struct DataUsageInfo {
    var wifiReceived: UInt64 = 0
    var wifiSent: UInt64 = 0
    var wirelessWanDataReceived: UInt64 = 0
    var wirelessWanDataSent: UInt64 = 0

    mutating func updateInfoByAdding(info: DataUsageInfo) {
        wifiSent += info.wifiSent
        wifiReceived += info.wifiReceived
        wirelessWanDataSent += info.wirelessWanDataSent
        wirelessWanDataReceived += info.wirelessWanDataReceived
    }
}

class DataUsage {

    private static let wwanInterfacePrefix = "pdp_ip"
    private static let wifiInterfacePrefix = "en"

    class func getDataUsage() -> DataUsageInfo {
        var interfaceAddresses: UnsafeMutablePointer<ifaddrs>? = nil

        var dataUsageInfo = DataUsageInfo()

        guard getifaddrs(&interfaceAddresses) == 0 else { return dataUsageInfo }

        var pointer = interfaceAddresses
        while pointer != nil {
            guard let info = getDataUsageInfo(from: pointer!) else {
                pointer = pointer!.pointee.ifa_next
                continue
            }
            dataUsageInfo.updateInfoByAdding(info: info)
            pointer = pointer!.pointee.ifa_next
        }

        freeifaddrs(interfaceAddresses)

        return dataUsageInfo
    }

    private class func getDataUsageInfo(from infoPointer: UnsafeMutablePointer<ifaddrs>) -> DataUsageInfo? {
        let pointer = infoPointer

        let name: String! = String(cString: infoPointer.pointee.ifa_name)
        let addr = pointer.pointee.ifa_addr.pointee

        return dataUsageInfo(from: pointer, name: name)

            dataUsageInfo.wifiSent += UInt64(networkData?.pointee.ifi_obytes ?? 0)
            dataUsageInfo.wifiReceived += UInt64(networkData?.pointee.ifi_ibytes ?? 0)
        } else if name.hasPrefix(wwanInterfacePrefix) {
            networkData = unsafeBitCast(pointer.pointee.ifa_data, to: UnsafeMutablePointer<if_data>.self)
            dataUsageInfo.wirelessWanDataSent += UInt64(networkData?.pointee.ifi_obytes ?? 0)
            dataUsageInfo.wirelessWanDataReceived += UInt64(networkData?.pointee.ifi_ibytes ?? 0)
