我试图跟踪每天的数据使用情况。我得到了一些跟踪数据使用情况的提示,但没有得到如何计算1天的数据使用情况。 IOS应用程序“我的数据管理器”跟踪数据使用情况并提供每日/每月的使用情况。每天跟踪iPhone数据使用情况

什么可能是背后的逻辑,让特定的时间间隔(1天/ 1个月)的数据使用情况如何?

数据使用情况的跟踪代码:

- (NSArray *)getDataCounters 
{ 
    BOOL success; 
    struct ifaddrs *addrs; 
    const struct ifaddrs *cursor; 
    const struct if_data *networkStatisc; 

    int WiFiSent = 0; 
    int WiFiReceived = 0; 
    int WWANSent = 0; 
    int WWANReceived = 0; 

    NSString *name=[[[NSString alloc]init]autorelease]; 

    success = getifaddrs(&addrs) == 0; 
    if (success) 
    { 
     cursor = addrs; 
     while (cursor != NULL) 
     { 
      name=[NSString stringWithFormat:@"%s",cursor->ifa_name]; 
      NSLog(@"ifa_name %s == %@\n", cursor->ifa_name,name); 
      // names of interfaces: en0 is WiFi ,pdp_ip0 is WWAN 

      if (cursor->ifa_addr->sa_family == AF_LINK) 
      { 
       if ([name hasPrefix:@"en"]) 
       { 
        networkStatisc = (const struct if_data *) cursor->ifa_data; 
        WiFiSent+=networkStatisc->ifi_obytes; 
        WiFiReceived+=networkStatisc->ifi_ibytes; 
        NSLog(@"WiFiSent %d ==%d",WiFiSent,networkStatisc->ifi_obytes); 
        NSLog(@"WiFiReceived %d ==%d",WiFiReceived,networkStatisc->ifi_ibytes); 
       } 

       if ([name hasPrefix:@"pdp_ip"]) 
       { 
        networkStatisc = (const struct if_data *) cursor->ifa_data; 
        WWANSent+=networkStatisc->ifi_obytes; 
        WWANReceived+=networkStatisc->ifi_ibytes; 
        NSLog(@"WWANSent %d ==%d",WWANSent,networkStatisc->ifi_obytes); 
        NSLog(@"WWANReceived %d ==%d",WWANReceived,networkStatisc->ifi_ibytes); 
       } 
      } 

      cursor = cursor->ifa_next; 
     } 

     freeifaddrs(addrs); 
    }  

    return [NSArray arrayWithObjects:[NSNumber numberWithInt:WiFiSent], [NSNumber numberWithInt:WiFiReceived],[NSNumber numberWithInt:WWANSent],[NSNumber numberWithInt:WWANReceived], nil]; 
}

这不是你自己的代码。这是从http://stackoverflow.com/questions/7946699/iphone-data-usage-tracking-monitoring/8014012#8014012确切副本。 -1为... –

据我知道有没有办法得到一段时间的信息,你只能得到当前的数据。因此,您应该跟踪数据使用情况并根据当前日期进行存储。然后你可以显示先前跟踪的信息。
