IOS 怎么获取外设的广播数据AdvData

(void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI{ ……}
这个方法中的advertisementData只能抓取到下面的键值
{
kCBAdvDataIsConnectable = 1;
kCBAdvDataLocalName = SimpleBLEPeripheral;
kCBAdvDataServiceUUIDs = ( FFF0 );
kCBAdvDataTxPowerLevel = 0;
}
simpleBLEPeripheral.c的 avertData数组的内容，也就是下图报文中的AdvData

NSArray *keys = [advertisementData allKeys];
NSData *dataAmb, *dataObj;
for (int i = 0; i < [keys count]; ++i) {
      id key = [keys objectAtIndex: i];
      NSString *keyName = (NSString *) key;
      NSObject *value = [advertisementData objectForKey: key];
      if ([value isKindOfClass: [NSArray class]]) {
         printf(" key: %s\n", [keyName cStringUsingEncoding: NSUTF8StringEncoding]);
         NSArray *values = (NSArray *) value;
         for (int j = 0; j < [values count]; ++j) {
            if ([[values objectAtIndex: j] isKindOfClass: [CBUUID class]]) {
                  CBUUID *uuid = [values objectAtIndex: j];
                  NSData *data = uuid.data;
                  if (j == 0) {
                     dataObj = uuid.data;
                  } else {
                     dataAmb = uuid.data;
                  }
                  printf("    uuid(%d):", j);
                  for (int j = 0; j < data.length; ++j)
                     printf(" %02X", ((UInt8 *) data.bytes)[j]);
                  printf("\n");
            } else {
                  const char *valueString = [[value description] cStringUsingEncoding: NSUTF8StringEncoding];
                  printf("    value(%d): %s\n", j, valueString);
            }
         }
      } else {
         const char *valueString = [[value description] cStringUsingEncoding: NSUTF8StringEncoding];
         printf(" key: %s, value: %s\n", [keyName cStringUsingEncoding: NSUTF8StringEncoding], valueString);
      }
}
