检测运营商连接类型(3G / EDGE / GPRS)检测运营商连接类型(3G / EDGE / G

2019-06-17 09:54发布

我怎样才能承载网络的连接类型?

  • 我能够得到,如果连接是使用WIFI或WWAN Reachability
  • 我能够获得网络标志

    可达性标志状态:WR牛逼------ localWiFiStatusForFlags

  • 我能够得到WIFI SSID使用CaptiveNetwork

支持的接口:(EN0)

en0 => {  
    BSSID = "xx:xx:xx:xx:xx:xx";  
    SSID = MyWifiNetwork;  
    SSIDDATA = <x1x1x1x1 x1x1x1x1 x1>;  
}  

但我不能够differenziate 3G,EDGE或GPRS连接。

任何想法, 也使用的是iOS私有API?

谢谢。

Answer 1:

从iOS的7,你可以使用:

CTTelephonyNetworkInfo *telephonyInfo = [CTTelephonyNetworkInfo new];
NSLog(@"Current Radio Access Technology: %@", telephonyInfo.currentRadioAccessTechnology);
[NSNotificationCenter.defaultCenter addObserverForName:CTRadioAccessTechnologyDidChangeNotification 
                                                object:nil 
                                                 queue:nil 
                                            usingBlock:^(NSNotification *note) 
{
    NSLog(@"New Radio Access Technology: %@", telephonyInfo.currentRadioAccessTechnology);
}];

我还发现这个检测缓慢或快速连接:

- (BOOL)isFast:(NSString*)radioAccessTechnology {
    if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyGPRS]) {
        return NO;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyEdge]) {
        return NO;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyWCDMA]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSDPA]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyHSUPA]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMA1x]) {
        return NO;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORev0]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevA]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyCDMAEVDORevB]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyeHRPD]) {
        return YES;
    } else if ([radioAccessTechnology isEqualToString:CTRadioAccessTechnologyLTE]) {
        return YES;
    }

    return YES;
}


Answer 2:

在这里, OLD的解决方案, 使用私有API,特别是SoftwareUpdateServices.framework

Class NetworkMonitor = NSClassFromString(@"SUNetworkMonitor");
NSLog(@"TYPE: %d", [NetworkMonitor currentNetworkType]);

它返回:

0:无数据
1:WIFI
2:GPRS / EDGE
3:3G

希望这有助于社区。



Answer 3:

接受的答案是不工作在iOS 10.我发现了一个解决办法,并设置在AppDelegate中的计时器被检查房子currentRadioAccessTechnology每5秒。 因此,我们还需要一个函数来检查,如果WIFI连接可用来代替无线接入技术。

检查WIFI连接可用:

class func isConnectedToWlan() -> Bool {
    var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, 
                         sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
    zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
    zeroAddress.sin_family = sa_family_t(AF_INET)

    let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
        $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
            SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
        }
    }

    var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
    if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
        return false
    }

    //Only Working for WIFI
     let isReachable = flags == .reachable
     let needsConnection = flags == .connectionRequired

     return isReachable && !needsConnection
}

设置计时器是这样的:

Timer.scheduledTimer(timeInterval: TimeInterval.seconds(5.0), target: self, selector:      
                           #selector(showNetworkMessage), userInfo: nil, repeats: true)

选择被称为每5秒:

    guard !Reachability.isConnecteToWlan() else {
        //Connected to WLAN
        return
    }
    guard let currentRadioAccessTechnology = info.currentRadioAccessTechnology else {
        // No internet connection
        return
    }
    guard (currentRadioAccessTechnology == CTRadioAccessTechnologyGPRS 
             || currentRadioAccessTechnology == CTRadioAccessTechnologyEdge) else {
        // 3G, LTE fast radio access Technology
        return
    }

    if lastRadioAccessTechnology != nil {
        guard let lastRadioAccessTechnology = lastRadioAccessTechnology, 
            (lastInfo != currentRadioAccessTechnology || 
              lastInfo != currentRadioAccessTechnology) else {
            //Internet connection did not change
            return
        }
    }
    // Internet connection changed to Edge or GPRS
    // Store lastRadioAccessTechnology to check if internet connection changed
    lastRadioAccessTechnology = currentRadioAccessTechnology


Answer 4:

我的工作需要认识到其互联网连接的类型,目前正在使用的(WIFI,3G,Edge等)的能力的iPhone应用程序。 我发现了一个简单的方法,通过使用苹果可达示例代码进行检查。 似乎有关于这个网上信息的不足,我希望这可以帮助别人。

首页复印Reachability.m / .H到你的项目,包括的#include“Reachability.h”到类。

Reachability *reach = [[Reachability alloc]init];
if (reach.internetConnectionStatus == NotReachable) {
    NSLog(@"No Connection Found");
} else if (reach.internetConnectionStatus == ReachableViaCarrierDataNetwork) {
    NSLog(@"3G or Edge");
} else if (reach.internetConnectionStatus == ReachableViaWiFiNetwork) {
    NSLog(@"Wifi Connection");
}
[reach release];

此代码可能无法做到这一点的最好办法,但它似乎是最简单的方法。
