bluetooth lowenergy - ios scanning different device by counting bits -

i working on ble scanning modules scanning devices if bit 0x00 shown 10 times or more. when more 1 identical device scanned, console shows alternate 0x00 , 0x01 in nslog . since use 1 integer counter count presence of 0x00 bits, override-ed . please tell me way implement key/value data structure save uuid , count storing scannedperipheral ?

the below working

  for(nsuinteger  = 0 ; < [ _ble.scannedperipheral count ] ; ++){             deviceperiperal *device;             nsstring *uuid = [_ble.scannedperipheralkey objectatindex:i];             if (uuid)             {                 device = [_ble.scannedperipheral objectforkey:uuid];                 if([self isemptyarrayornil:[_dbman getdevicerecord:device.uuid ] ]){                      nslog(@"pair bit %@ ," ,  device.pairbit );                     const unsigned char ssss[1] = {0x00};                     nsdata* pairbi =  [nsdata datawithbytes:(const void *)ssss length:(sizeof(unsigned char) * 1)];                     const unsigned char sslow[1] = {0x01};                     nsdata* pairx =  [nsdata datawithbytes:(const void *)sslow length:(sizeof(unsigned char) * 1)];                      if ([device.pairbit  isequaltodata:pairbi ]){                          pcount++;                         if(pcount > 9){                             nslog(@"pair bit paired " );                             nslog (@"device = %@", device.uuid);                                                                                    }                     }else if([device.pairbit  isequaltodata:pairx ]){                                                     nslog(@"pair bit not matched " );                         pcount=0;                                                 }                 }else{                     // others                     nslog(@"pair bit paired before" );                     nslog (@"device = %@", device.uuid);                 }         }
