iOS我无法获得我的运营商名称 [英] iOS I can't get my carrier name

问题描述

如此处所述 - > 以编程方式从iPhone检索运营商名称

as explained here -> Retrieving Carrier Name from iPhone Programmatically

我正在尝试获取我的运营商名称，我正在使用此代码

i'm trying to get my carrier's name, i'm using this code

CTTelephonyNetworkInfo *netinfo = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [netinfo subscriberCellularProvider];
NSLog(@"Carrier Name: %@", [carrier carrierName]);
[netinfo release];

但我收到 [carrier carrierName] ：未找到实例方法'-carrierName'

but i receive a warning on [carrier carrierName]: Instance method '-carrierName' not found

我已经添加了框架coretelephony到我的项目但是当我执行我的应用程序时它崩溃了！

i've added and the framework coretelephony to my project but when i execute my app it crashes!

感谢所有人！

推荐答案

您是否明确导入了CTCarrier？

Did you explicitly import CTCarrier?

#import <CoreTelephony/CTCarrier.h>
