IOS實時監控上傳下載速度

在開發中要獲取網絡類型是很簡單的，導入Reachability直接獲取狀態就行了，現在我們要做一個類似下載器的那種實時把上傳下載速度顯示出來。

需要用到的頭文件 

使用Reachability

要測速度所以必須要有一個定時器，咱們為了不耗用戶的流量，取的是數據的總量，然后減去上一次的檢測的總量，得出的就是速度。網絡現在分為wifi以及wwan兩種類型。

首先頭文件.h建立一個檢測的數據類

@interface MonitorData : NSObject

@property (assign, nonatomic) float wwanSend;

@property (assign, nonatomic) float wwanReceived;

@property (assign, nonatomic) float wifiSend;

@property (assign, nonatomic) float wifiReceived;

@end

 

然后建立一個檢測類

@interface MonitorFlow : NSObject

//開始檢測

- (void)startMonitor;

//停止檢測

- (void)stopMonitor;

@end

實現文件.M

//成員變量是內部可見的

@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

直接把代碼附上，里面有注釋

@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{

// 上傳、下載

//不需要連通網絡獲取的是總的數據

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上傳速度：%@",[NSString stringWithFormat:@"%.0f KB/s",wifiSend]);

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

}

break;

case ReachableViaWWAN:

{

float wwanSend = monitor.wwanSend - self.tempWWANReceived;

float wwanReceived = monitor.wifiReceived - self.tempWWANSend;

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

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

}

break;

default:

{

NSLog(@"無網絡");

}

break;

}

[self currentFlow];

}

//賦值當前流量

- (void)currentFlow{

MonitorData *monitor = [self getMonitorDataDetail];

self.tempWifiSend = monitor.wifiSend;

self.tempWifiReceived = monitor.wifiReceived;

self.tempWWANSend = monitor.wwanSend;

self.tempWWANReceived = monitor.wwanReceived;

}

//上傳、下載總額流量

- (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;

}
