在开发中要获取网络类型是很简单的，导入Reachability直接获取状态就行了，现在我们要做一个类似下载器的那种实时把上传下载速度显示出来。

需要用到的头文件

使用Reachability

要测速度所以必须要有一个定时器，咱们为了不耗用户的流量，取的是数据的总量，然后减去上一次的检测的总量，得出的就是速度。网络现在分为wifi以及wwan两种类型。

首先头文件.h建立一个检测的数据类

@interface MonitorData : NSObject

@property (assign, nonatomic) float wwanSend;

@property (assign, nonatomic) float wwanReceived;

@property (assign, nonatomic) float wifiSend;

@property (assign, nonatomic) float wifiReceived;

@end

然后建立一个检测类

@interface MonitorFlow : NSObject

//开始检测

- (void)startMonitor;

//停止检测

- (void)stopMonitor;

@end

实现文件.M

//成员变量是内部可见的

@interface MonitorFlow ()

@property (strong,nonatomic) NSTimer *timer;

@property (assign, nonatomic) float tempWWANReceived;

@property (assign, nonatomic) float tempWWANSend;

@property (assign, nonatomic) float tempWifiReceived;

@property (assign, nonatomic) float tempWifiSend;

@end

直接把代码附上，里面有注释

@implementation MonitorFlow

- (void)startMonitor {

[self currentFlow];

self.timer = [NSTimer timerWithTimeInterval:1.0 target:self selector:@selector(refreshFlow) userInfo:nil repeats:YES];

[[NSRunLoop currentRunLoop] addTimer:self.timer forMode:NSRunLoopCommonModes];

}

- (void)stopMonitor{

[self.timer invalidate];

}

- (void)refreshFlow{

// 上传、下载

//不需要连通网络获取的是总的数据

Reachability *reachability = [Reachability reachabilityWithHostName:@"Yes-Cui"];

MonitorData *monitor = [self getMonitorDataDetail];

switch (reachability.currentReachabilityStatus) {

case ReachableViaWiFi:

{

float wifiSend = monitor.wifiSend - self.tempWifiSend;

float wifiReceived = monitor.wifiReceived - self.tempWifiReceived;

NSLog(@"wifi上传速度：%@",[NSString stringWithFormat:@"%.0f KB/s",wifiSend]);

NSLog(@"wifi下载速度：%@",[NSString stringWithFormat:@"%.0f KB/s",wifiReceived]);

}

break;

case ReachableViaWWAN:

{

float wwanSend = monitor.wwanSend - self.tempWWANReceived;

float wwanReceived = monitor.wifiReceived - self.tempWWANSend;

NSLog(@"wwan上传速度：%@",[NSString stringWithFormat:@"%.0f KB/s",wwanSend]);

NSLog(@"wwan下载速度：%@",[NSString stringWithFormat:@"%.0f KB/s",wwanReceived]);

}

break;

default:

{

NSLog(@"无网络");

}

break;

}

[self currentFlow];

}

//赋值当前流量

- (void)currentFlow{

MonitorData *monitor = [self getMonitorDataDetail];

self.tempWifiSend = monitor.wifiSend;

self.tempWifiReceived = monitor.wifiReceived;

self.tempWWANSend = monitor.wwanSend;

self.tempWWANReceived = monitor.wwanReceived;

}

//上传、下载总额流量

- (MonitorData *)getMonitorDataDetail

{

BOOL success;

struct ifaddrs *addrs;

struct ifaddrs *cursor;

struct if_data *networkStatisc;

long tempWiFiSend = 0;

long tempWiFiReceived = 0;

long tempWWANSend = 0;

long tempWWANReceived = 0;

NSString *dataName;

success = getifaddrs(&addrs) == 0;

if (success)

{

cursor = addrs;

while (cursor != NULL)

{

dataName = [NSString stringWithFormat:@"%s",cursor->ifa_name];

if (cursor->ifa_addr->sa_family == AF_LINK)

{

if ([dataName hasPrefix:@"en"])

{

networkStatisc = (struct if_data *) cursor->ifa_data;

tempWiFiSend += networkStatisc->ifi_obytes;

tempWiFiReceived += networkStatisc->ifi_ibytes;

}

if ([dataName hasPrefix:@"pdp_ip"])

{

networkStatisc = (struct if_data *) cursor->ifa_data;

tempWWANSend += networkStatisc->ifi_obytes;

tempWWANReceived += networkStatisc->ifi_ibytes;

}

}

cursor = cursor->ifa_next;

}

freeifaddrs(addrs);

}

MonitorData *monitorData = [MonitorData new];

monitorData.wifiSend = tempWiFiSend/1024;

monitorData.wifiReceived = tempWiFiReceived/1024;

monitorData.wwanSend = tempWWANSend/1024;

monitorData.wwanReceived = tempWWANReceived/1024;

return monitorData;

}

粘贴的格式错乱了自己排序一下，哈哈希望对大家有帮助。
