iOS获取链接速度(路由器速度测试) [英] iOS Get Link Speed (Router Speed Test)

问题描述

我想通过iOS应用测试连接的路由器(wifi调制解调器)的速度.

I want to test speed of connected router(wifi modem) from iOS app.

我在这里找到了一些东西以编程方式获取链接速度?，但是找不到sockios.h和ethtool.h

I've found something here Get link speed programmatically? but could not found sockios.h and ethtool.h

是否可以将此代码移植到Objective-C或还有另一种方法?

Is it possible to port this code to Objective-C or is there another way?

对不起，缺少信息和我的英语不好.

Sorry for the missing info and my poor english.

我想测试ios设备和连接的wifi调制解调器之间的链接速度(传输速率).

I want to test link speed (tx rate) between ios device and connected wifi modem.

在CWInterface类中有一个名为txRate的属性.我想在Cocoa Touch中获取这些数据.

There was a property named txRate in CWInterface class. I want to get that data in Cocoa Touch.

/*!
* @property
* @abstract Current transmit rate (Mbps) of the CoreWLAN interface. 
* @discussion Dynamically queries the interface for the current transmit rate.
*/
@property(readonly) NSNumber *txRate NS_DEPRECATED_MAC(10_6, 10_7);

推荐答案

最后我找到了解决方案.

Finally I've found the solution.

#include <ifaddrs.h>
#include <net/if.h>

+ (double)getRouterLinkSpeed
{
    BOOL   success;
    struct ifaddrs *addrs;
    const struct ifaddrs *cursor;
    const struct if_data *networkStatisc;

    double linkSpeed = 0;

    NSString *name = [[NSString alloc] init];

    success = getifaddrs(&addrs) == 0;
    if (success)
    {
        cursor = addrs;
        while (cursor != NULL)
        {
            name=[NSString stringWithFormat:@"%s",cursor->ifa_name];

            if (cursor->ifa_addr->sa_family == AF_LINK)
            {
                if ([name hasPrefix:@"en"])
                {
                    networkStatisc = (const struct if_data *) cursor->ifa_data;
                    linkSpeed = networkStatisc->ifi_baudrate;
                }
            }
            cursor = cursor->ifa_next;
        }
        freeifaddrs(addrs);
    }

    return linkSpeed;
}
