Question

在我的应用程序中，我想获得移动网络信号强度和网络提供商名称，在下面的代码中，它返回信号强度，但我感觉不准确，因为当强度值达到60％时，信号棒也显示为满。并且网络提供商名称作为carrier.i'm返回每2秒调用一次这个方法。

-(void)UpdateLabelWithSignal{
   int str = CTGetSignalStrength();
   NSLog(@"SignalStrength:%d",str);
   NSLog(@"SignalStrength:%@",[NSString stringWithFormat:@"%d",str]);
   SignalLabel.text = [NSString stringWithFormat:@"%d",str];

}

//获取网络提供商名称的代码

    CTTelephonyNetworkInfo *netinfo = [[CTTelephonyNetworkInfo alloc] init];
    CTCarrier *carrier = [netinfo subscriberCellularProvider];
    NSLog(@"MY NAME:%@",carrier.carrierName);

如果你想让它每隔几秒准确更新一次。那就是代码。

 - (void)viewDidLoad
 {
  [super viewDidLoad];

  printf("signal strength: %d\n", CTGetSignalStrength());
 slimeDeathAnimTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selector:@selector(UpdateLabelWithSignal) userInfo:nil repeats:YES];
  CTTelephonyNetworkInfo *netinfo = [[CTTelephonyNetworkInfo alloc] init];
  CTCarrier *carrier = [netinfo subscriberCellularProvider];
  NSLog(@"MY NAME:%@",carrier.carrierName);

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

  }

-(void)UpdateLabelWithSignal{

int str = CTGetSignalStrength();
NSLog(@"SignalStrength:%d",str);
  NSLog(@"SignalStrength:%@",[NSString stringWithFormat:@"%d",str]);
SignalLabel.text = [NSString stringWithFormat:@"%d",str];

}

如何找到准确的移动信号强度和服务提供商名称？
