Detect carrier connection type (3G / EDGE / GPRS)
提问by elp
How can i get the type of connection of a carrier network?
如何获取运营商网络的连接类型？
- I'm able to get if connection is WIFI or WWAN using
Reachabilityclass I'm able to get network flags
Reachability Flag Status: WR t------ localWiFiStatusForFlags
I'm able to get WIFI SSID using
CaptiveNetwork
- 如果连接是 WIFI 或 WWAN，我可以使用
Reachability类获得 我能够获得网络标志
可达标志状态：WR t------ localWiFiStatusForFlags
我可以使用 WIFI SSID
CaptiveNetwork
Supported interfaces: ( en0 )
支持的接口：（EN0）
en0 => {
BSSID = "xx:xx:xx:xx:xx:xx";
SSID = MyWifiNetwork;
SSIDDATA = <x1x1x1x1 x1x1x1x1 x1>;
}
But i'm not able to differenziate 3G, EDGE or GPRS connection.
但我无法区分 3G、EDGE 或 GPRS 连接。
Any idea also using iOS private API?
任何想法也使用iOS私有API？
thanks.
谢谢。

From iOS 7 on you can use:
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);
}];
I have also found this to detect a slow or fast connection:
我还发现这可以检测慢速或快速连接：
- (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;
}

Here the OLDsolution, using private API, in particular SoftwareUpdateServices.framework
这里的OLD解决方案，特别是使用私有 APISoftwareUpdateServices.framework
Class NetworkMonitor = NSClassFromString(@"SUNetworkMonitor");
NSLog(@"TYPE: %d", [NetworkMonitor currentNetworkType]);
It returns:
它返回：
0: NO DATA
1: WIFI
2: GPRS/EDGE
3: 3G
0：无数据
1：WIFI
2：GPRS/EDGE
3：3G
hope this helps community.
希望这有助于社区。

The accepted answer isn't working on iOS 10. I found a workaround and setup a timer in AppDelegate which is checking the property currentRadioAccessTechnology every 5 seconds. Therefore we also need a function to check if WIFI connection is available instead of radio access technology.
接受的答案不适用于 iOS 10。我找到了一种解决方法并在 AppDelegate 中设置了一个计时器，它每 5 秒检查一次属性 currentRadioAccessTechnology。因此，我们还需要一个功能来检查 WIFI 连接是否可用，而不是无线电接入技术。
Check if WIFI Connection is available:
检查WIFI连接是否可用：
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) {
Timer.scheduledTimer(timeInterval: TimeInterval.seconds(5.0), target: self, selector:
#selector(showNetworkMessage), userInfo: nil, repeats: true)
.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
}
Setup the timer like this:
像这样设置计时器：
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
Selector which is called every 5 seconds:
每 5 秒调用一次的选择器：
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];

I am working on an iPhone application that requires the ability to recognize which type of internet connection is currently being used (Wifi, 3G, Edge, etc). I found a simple way to check by using Apples Reachability sample code. There seems to be a shortage of information about this online, I hope this can help someone.
我正在开发一个 iPhone 应用程序，它需要能够识别当前使用的互联网连接类型（Wifi、3G、Edge 等）。我找到了一种使用 Apples Reachability 示例代码进行检查的简单方法。网上好像缺少这方面的资料，希望可以帮到大家。
First copy Reachability.m/.h into your project and include #include "Reachability.h" into your class.
首先Reachability.m / .H复制到您的项目，包括的#include“Reachability.h”到类。
##代码##This code may not be the best way to accomplish this, but it appears to be the most simple approach.
此代码可能不是实现此目的的最佳方法，但它似乎是最简单的方法。
