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 = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [telephonyInfo subscriberCellularProvider];
NSString *currentCountry = [carrier carrierName]; // 运营商名字
NSLog(@"[carrier isoCountryCode]==%@,[carrier allowsVOIP]=%d,[carrier mobileCountryCode=%@,[carrier mobileCountryCode]=%@",[carrier isoCountryCode],[carrier allowsVOIP],[carrier mobileCountryCode],[carrier mobileNetworkCode]);
}
2.可以用CoreTelephony监控通话信息。
CTCallCenter *center = [[CTCallCenter alloc] 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 = [AFHTTPSessionManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
[manager GET:@"http://g3.letv.cn/recommend?format=1" parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (responseObject && [responseObject isKindOfClass:[NSDictionary class]]) {
NSLog(@"%@ >> %@", responseObject, responseObject[@"desc"]);
}
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
}];
}
