iOS|iOS OC 监听当前wifi网速 iOSOC监听当前wifi网速

思路：先获取到总的流量信息，然后用当前的总下行流量减去上一秒的下行流量得到网速！
【iOS|iOS OC 监听当前wifi网速】具体实现在以下三个方法！

//获取下行速度- (void)getByteRate {longlongintrate; longlongintcurrentBytes = [selfgetInterfaceBytes]; if(self.lastBytes) {//用上当前的下行总流量减去上一秒的下行流量达到下行速录rate = currentBytes -self.lastBytes; }else{self.isFirstRate=NO; } //保存上一秒的下行总流量 self.lastBytes= [selfgetInterfaceBytes]; //格式化一下 NSString*rateStr = [selfformatNetWork:rate]; NSLog(@"当前网速%@",rateStr); self.playerControl.LoadingView.rateLabel.text = [NSStringstringWithFormat:@"%@",rateStr]; }

//获取数据流量详情- (longlongint)getInterfaceBytes {structifaddrs*ifa_list =0, *ifa; if(getifaddrs(&ifa_list) == -1) {return 0; }uint32_tiBytes =0; //下行uint32_toBytes =0; //上行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=https://www.it610.com/article/=0)continue; if(strncmp(ifa->ifa_name,"lo",2)) {structif_data*if_data = https://www.it610.com/article/(structif_data*)ifa->ifa_data; iBytes += if_data->ifi_ibytes; oBytes += if_data->ifi_obytes; } }freeifaddrs(ifa_list); //返回下行的总流量 returniBytes; }

//格式化方法 - (NSString*)formatNetWork:(longlongint)rate {if(rate <1024) {return[NSStringstringWithFormat:@"%lldB/秒", rate]; }elseif(rate >=1024&& rate <1024*1024) {return[NSStringstringWithFormat:@"%.1fKB/秒", (double)rate /1024]; }elseif(rate >=1024*1024&& rate <1024*1024*1024){return[NSStringstringWithFormat:@"%.2fMB/秒", (double)rate / (1024*1024)]; }else{ return@"10Kb/秒"; }; }
