title: Signal strength in ios 8.3
body: <p>Apple has restricted API to fetch signal strength but there is a way to get this i found <a href="https://stackoverflow.com/questions/29795817/get-cellid-mcc-mnc-lac-signal-strength-quality-and-network-in-ios-8-3">here</a>.Is it a correct way to get signal strength. I am developing for iTunes store submission. Will apple reject my app? Solution provided by @Mateusz Mirkowski as follow :</p>
  
  <pre><code>UIApplication *app = [UIApplication sharedApplication];
  NSArray *subviews = [[[app valueForKey:@"statusBar"]     valueForKey:@"foregroundView"] subviews];
  NSString *dataNetworkItemView = nil;
  
  
       for (id subview in subviews) {
     if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarSignalStrengthItemView") class]])
     {
          dataNetworkItemView = subview;
          break;
      }
   }
  int signalStrength = [[dataNetworkItemView valueForKey:@"signalStrengthRaw"] intValue];
  
  NSLog(@"signal %d", signalStrength);
  </code></pre>
