获取iPhone/iPad设备网络类型（2G,3G,4G,WIF

目前我们获取手机网络类型主要还是用的 AFNetwork

但是AFNetwork有个问题就是类型不够充分，只能四种类型

typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) {
    AFNetworkReachabilityStatusUnknown          = -1,
    AFNetworkReachabilityStatusNotReachable     = 0,
    AFNetworkReachabilityStatusReachableViaWWAN = 1,
    AFNetworkReachabilityStatusReachableViaWiFi = 2,
};

1. AFNetworkReachabilityStatusUnknown 未知网络
2. AFNetworkReachabilityStatusNotReachable 无网络
3. AFNetworkReachabilityStatusReachableViaWWAN 蜂窝移动网络
4. AFNetworkReachabilityStatusReachableViaWiFi WIFI

具体获取代码如下

/**
 监测网络类型
 */
-(void)configReachabilityStatusByAFNetwork {
    AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
    [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
        [MyAppConfigModel sharedSingleton].netWorkReachabilityStatus = status;
        switch (status) {
            case AFNetworkReachabilityStatusUnknown:
                NSLog(@"⚠️⚠️⚠️⚠️⚠️⚠️⚠️当前网络：未知");
                break;
            case AFNetworkReachabilityStatusNotReachable:
                NSLog(@"⚠️⚠️⚠️⚠️⚠️⚠️⚠️当前网络：网络无连接\n请检查网络");
                break;
            case AFNetworkReachabilityStatusReachableViaWWAN:
                NSLog(@"⚠️⚠️⚠️⚠️⚠️⚠️⚠️当前网络：3G|4G");
                break;
            case AFNetworkReachabilityStatusReachableViaWiFi:
                NSLog(@"⚠️⚠️⚠️⚠️⚠️⚠️⚠️当前网络：WiFi");
                break;
            default:
                break;
        }
    }];
}

那么 如何获取蜂窝移动网络的具体类型呢？
这里就需要用到

#import <CoreTelephony/CoreTelephonyDefines.h>
#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>

具体代码如下

+ (NSInteger)getDeviceNetWorkingStatus{
    
    NSString *state = [[NSString alloc] init];
    NSInteger stateType = 0;
    
    AFNetworkReachabilityStatus netWorkReachabilityStatus =  [MyAppConfigModel sharedSingleton].netWorkReachabilityStatus;
    switch (netWorkReachabilityStatus) {
        case AFNetworkReachabilityStatusUnknown:
            state = @"无网络";
            stateType = 5;
            break;
        case AFNetworkReachabilityStatusNotReachable:
            state = @"无网络";
            stateType = 5;
            break;
        case AFNetworkReachabilityStatusReachableViaWWAN:
        {
            NSArray *typeStrings2G = @[CTRadioAccessTechnologyEdge,
                                       CTRadioAccessTechnologyGPRS,
                                       CTRadioAccessTechnologyCDMA1x];
         
            NSArray *typeStrings3G = @[CTRadioAccessTechnologyHSDPA,
                                       CTRadioAccessTechnologyWCDMA,
                                       CTRadioAccessTechnologyHSUPA,
                                       CTRadioAccessTechnologyCDMAEVDORev0,
                                       CTRadioAccessTechnologyCDMAEVDORevA,
                                       CTRadioAccessTechnologyCDMAEVDORevB,
                                       CTRadioAccessTechnologyeHRPD];
            
            NSArray *typeStrings4G = @[CTRadioAccessTechnologyLTE];
            
            CTTelephonyNetworkInfo *teleInfo= [[CTTelephonyNetworkInfo alloc] init];
            NSString *accessString = teleInfo.currentRadioAccessTechnology;
            if ([typeStrings4G containsObject:accessString]) {
                state = @"4G";
                stateType = 2;
            } else if ([typeStrings3G containsObject:accessString]) {
                state = @"3G";
                stateType = 3;
            } else if ([typeStrings2G containsObject:accessString]) {
                state = @"2G";
                stateType = 4;
            } else {
                state = @"无网络";
                stateType = 5;
            }
        }
            break;
        case AFNetworkReachabilityStatusReachableViaWiFi:
            state = @"WIFI";
            stateType = 1;
            break;
        default:
            state = @"无网络";
            stateType = 5;
            break;
    }
    
    NSLog(@"当前网络网络状态 %@",state);
    return stateType;
}
