流量統計

1 首先統計的流量爲 開機到如今 系統的全部流量 注： 此處說的流量不爲單獨的app －－－－－－－－－wifi - (NSString *)getInterfaceBytes { struct ifaddrs *ifa_list = 0, *ifa; if (getifaddrs(&ifa_list) == -1) { return 0; } uint32_t iBytes = 0; uint32_t oBytes = 0; for (ifa = ifa_list; ifa; ifa = ifa->ifa_next) { if (AF_LINK != ifa->ifa_addr->sa_family) continue; if (!(ifa->ifa_flags & IFF_UP) && !(ifa->ifa_flags & IFF_RUNNING)) continue; if (ifa->ifa_data == 0) continue; //Wifi if (strncmp(ifa->ifa_name, "lo", 2)) { struct if_data *if_data = (struct if_data *)ifa->ifa_data; iBytes += if_data->ifi_ibytes; oBytes += if_data->ifi_obytes; NSLog(@"%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes); } } freeifaddrs(ifa_list); uint32_t bytes = 0; bytes = iBytes+oBytes; NSLog(@"%d",bytes); //將bytes單位轉換 if(bytes < 1024) // B { NSLog(@"%@",[NSString stringWithFormat:@"%dB", bytes]); return [NSString stringWithFormat:@"%dB", bytes]; } else if(bytes >= 1024 && bytes < 1024 * 1024) // KB { NSLog(@"%@",[NSString stringWithFormat:@"%.1fKB", (double)bytes / 1024]); return [NSString stringWithFormat:@"%.1fKB", (double)bytes / 1024]; } else if(bytes >= 1024 * 1024 && bytes < 1024 * 1024 * 1024) // MB { NSLog(@"%@",[NSString stringWithFormat:@"%.2fMB", (double)bytes / (1024 * 1024)]); return [NSString stringWithFormat:@"%.2fMB", (double)bytes / (1024 * 1024)]; } else // GB { NSLog(@"%@",[NSString stringWithFormat:@"%.3fGB", (double)bytes / (1024 * 1024 * 1024)]); return [NSString stringWithFormat:@"%.3fGB", (double)bytes / (1024 * 1024 * 1024)]; } } －－－－－－－－－－－gps -(NSString *)getGprs3GFlowIOBytes { struct ifaddrs *ifa_list = 0, *ifa; if (getifaddrs(&ifa_list) == -1) { return 0; } uint32_t iBytes = 0; uint32_t oBytes = 0; for (ifa = ifa_list; ifa; ifa = ifa->ifa_next) { if (AF_LINK != ifa->ifa_addr->sa_family) continue; if (!(ifa->ifa_flags & IFF_UP) && !(ifa->ifa_flags & IFF_RUNNING)) continue; if (ifa->ifa_data == 0) continue; //3G或者GPRS if (!strcmp(ifa->ifa_name, "pdp_ip0")) { struct if_data *if_data = (struct if_data *)ifa->ifa_data; iBytes += if_data->ifi_ibytes; oBytes += if_data->ifi_obytes; NSLog(@"%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes); } } freeifaddrs(ifa_list); uint32_t bytes = 0; bytes = iBytes + oBytes; //將bytes單位轉換 if(bytes < 1024) // B { return [NSString stringWithFormat:@"%dB", bytes]; } else if(bytes >= 1024 && bytes < 1024 * 1024) // KB { return [NSString stringWithFormat:@"%.1fKB", (double)bytes / 1024]; } else if(bytes >= 1024 * 1024 && bytes < 1024 * 1024 * 1024) // MB { return [NSString stringWithFormat:@"%.2fMB", (double)bytes / (1024 * 1024)]; } else // GB { return [NSString stringWithFormat:@"%.3fGB", (double)bytes / (1024 * 1024 * 1024)]; } }
