是否可以使用iOS SDK检测LTE连接？ [英] Is it possible to detect LTE connection using iOS SDK?

问题描述

我正在使用可访问性API来检测我当前的连接，但我只能区分WIFI和3G。

I'm using the reachability API to detect my current connection, but I can only distinguish between WIFI and 3G.

我得到以下标志：

LTE： kSCNetworkReachabilityFlagsIsLocalAddress | kSCNetworkReachabilityFlagsIsWWAN | kSCNetworkReachabilityFlagsTransientConnection | kSCNetworkReachabilityFlagsReachable

WIFI ： kSCNetworkReachabilityFlagsIsDirect | kSCNetworkReachabilityFlagsReachable

问题是LTE返回与3G连接相同的标志。有没有办法确定用户目前是否有LTE或3G？

The problem is that LTE returns the same flags as a 3G connection. Is there any way to determine whether the user currently has LTE or 3G?

推荐答案

从iOS 7开始，你可以找到它使用CoreTelephony框架中 CTTelephonyNetworkInfo 的 currentRadioAccessTechnology 属性。

As of iOS 7, you can find this out using the currentRadioAccessTechnology property of CTTelephonyNetworkInfo in the CoreTelephony framework.

#import <CoreTelephony/CTTelephonyNetworkInfo.h>

CTTelephonyNetworkInfo *networkInfo = [CTTelephonyNetworkInfo new];

if ([networkInfo.currentRadioAccessTechnology isEqualToString:CTRadioAccessTechnologyLTE]) {
    // ...
}
