在我的应用程序中,我想获取移动网络信号强度和网络提供商名称, 在下面的代码中,它返回了信号强度,但我感觉它并不准确,因为当强度值达到 60% 时,信号棒也显示满了。并且网络提供商名称作为运营商返回。我是每 2 秒调用一次此方法。
-(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);
如果您希望它每隔几秒准确更新一次。这里是代码。
- (void)viewDidLoad
{
[super viewDidLoad];
printf("signal strength: %d\n", CTGetSignalStrength());
slimeDeathAnimTimer = [NSTimer scheduledTimerWithTimeInterval:0.5 target:self selectorselector(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];
}
关于iphone - 如何找到准确的移动信号强度和服务提供商名称?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/16785734/
