iOS I can't get my carrier name

2019-03-16 13:05发布

as explained here -> Retrieving Carrier Name from iPhone Programmatically

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];

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

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

thanks to all!

Did you explicitly import CTCarrier?

#import <CoreTelephony/CTCarrier.h>

I have same problem too,and try to log by device:

NSLog(@"carrierName = %@",carrier.carrierName);
NSLog(@"mobileCountryCode = %@",carrier.mobileCountryCode);
NSLog(@"mobileNetworkCode = %@",carrier.mobileNetworkCode);
NSLog(@"isoCountryCode = %@",carrier.isoCountryCode);
NSLog(@"allowVOIP = %d",carrier.allowsVOIP);

result:

2012-05-29 11:48:31.466 carrierTest[357:707] mobileCountryCode = 466

2012-05-29 11:48:31.469 carrierTest[357:707] mobileNetworkCode = 97

2012-05-29 11:48:31.470 carrierTest[357:707] isoCountryCode = tw

2012-05-29 11:48:31.472 carrierTest[357:707] allowVOIP = 1

the object carrierName is "....." in run stack,actually it should be "台湾大哥大"

it seem like string encoding problem cause i can't get it? I have no idea...

you can try the other carrier SIM card.

Try

NSLog(@"Carrier Name: %@", carrier.carrierName);

instead.
