iOS检测当前设备运营商类型

导入系统库 CoreTelephony.framework，并在相关.h文件中导入，代码如下

#import <CoreTelephony/CTTelephonyNetworkInfo.h>

#import<CoreTelephony/CTCarrier.h>

- (void)check

{

CTTelephonyNetworkInfo*info = [[CTTelephonyNetworkInfoalloc]init];

CTCarrier*carrier = info.subscriberCellularProvider;

NSString*carrierName = carrier.carrierName;

NSString*mobileCountryCode = carrier.mobileCountryCode;

NSString*mobileNetworkCode = carrier.mobileNetworkCode;

NSLog(@"carrier=%@ /n carrierName=%@ /n mobileCountryCode=%@ /n networkCode = %@",carrier,carrierName,mobileCountryCode,mobileNetworkCode);

}
