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
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。
