CoreTelephony运营商信息

CoreTelephony是苹果提供的用来访问用户的移动服务提供商的信息，比如它的唯一标识符，以及是否允许VoIP通话。获取当前通过的id以及状态。

CoreTelephony在iOS7之前是私有API，在iOS7之后苹果公开了CoreTelephony。

1.可以用CoreTelephony获取手机运营商的信息。

- (void)getcarrierName

{

    CTTelephonyNetworkInfo *telephonyInfo = [[CTTelephonyNetworkInfoalloc] init];

    CTCarrier *carrier = [telephonyInfosubscriberCellularProvider];

    NSString *currentCountry = [carriercarrierName];   //运营商名字

    NSLog(@"[carrier isoCountryCode]==%@,[carrier allowsVOIP]=%d,[carrier mobileCountryCode=%@,[carrier mobileCountryCode]=%@",[carrierisoCountryCode],[carrierallowsVOIP],[carriermobileCountryCode],[carriermobileNetworkCode]);

}

2.可以用CoreTelephony监控通话信息。

CTCallCenter *center = [[CTCallCenteralloc] init];

center.callEventHandler = ^(CTCall *call) {

    NSString *callState = call.callState;

    NSString *callID = call.callID;

};

3.号外:获取当前使用网络的运营商的信息。

- (void)networkMobile

{

    AFHTTPSessionManager *manager = [AFHTTPSessionManagermanager];

    manager.responseSerializer = [AFJSONResponseSerializerserializer];

    manager.requestSerializer = [AFJSONRequestSerializerserializer];

    manager.responseSerializer.acceptableContentTypes = [NSSetsetWithObjects:@"application/json",@"text/json", @"text/javascript",@"text/html", nil];

    

    [manager GET:@"http://g3.letv.cn/recommend?format=1"parameters:nilprogress:nilsuccess:^(NSURLSessionDataTask *_Nonnull task, id _Nullable responseObject) {

        if (responseObject && [responseObjectisKindOfClass:[NSDictionaryclass]]) {

            NSLog(@"%@ >> %@", responseObject, responseObject[@"desc"]);

        }

    } failure:^(NSURLSessionDataTask *_Nullable task, NSError *_Nonnull error) {

        

    }];

}
