CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
CTCarrier *carrier = [info subscriberCellularProvider];
if( carrier ==nil)
{
return(@"0");
}
NSString *code = [carrier mobileNetworkCode];
if([code isEqualToString:@""])
{
return(@"0");
}
if( [code isEqualToString:@"00"] || [code isEqualToString:@"02"] || [code isEqualToString:@"07"] )
{
ret =@"移动";
}
if( [code isEqualToString:@"01"] || [code isEqualToString:@"06"] )
