#import "sbsfirstviewcontroller.h"   @interface sbsfirstviewcontroller ()   @property (strong, nonatomic) clbeaconregion *beaconregion; @property (strong, nonatomic) cllocationmanager *locationmanager; @property  bool checkdidenterbusstop; @property (strong, nonatomic) clbeacon *selectedbeacon;  @end  @implementation sbsfirstviewcontroller   nsarray *buses; bool checkdidenterbusstop = no;  -(nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section{  if(checkdidenterbusstop == yes){     return [buses count]; } return 0;  }  -(uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:     (nsindexpath *)indexpath{  static nsstring *tableidentifier =@"buscell";   uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:tableidentifier];  if(cell==nil){      cell = [[uitableviewcell alloc]initwithstyle:uitableviewcellstyledefault reuseidentifier:tableidentifier];  }    cell.textlabel.text = [buses objectatindex:indexpath.row];    return cell;    }  - (void)viewdidload { [super viewdidload]; // additional setup after loading view, typically nib.  buses = [nsarray arraywithobjects:@"3", @"83", @"62", nil];  self.locationmanager = [[cllocationmanager alloc] init]; self.locationmanager.delegate = self;  [self initregion];  [self.locationmanager startmonitoringforregion:_beaconregion]; _beaconregion.notifyonentry = yes;  nslog(@"start monitoring");     }    -(void)initregion { nsuuid *demobusstopuuid = [[nsuuid alloc]initwithuuidstring:@"b9407f30-f5f8-466e-aff9-25556b57fe6d"];  self.beaconregion = [[clbeaconregion alloc]initwithproximityuuid:demobusstopuuid major:23118 minor:37538 identifier:@"estimoteatbusstop"];    }     -(void)locationmanager:(cllocationmanager *)manager didenterregion:(clregion *)region{  [self.locationmanager startrangingbeaconsinregion:self.beaconregion]; nslog(@"entered region");    }  -(void)locationmanager:(cllocationmanager *)manager didexitregion:(clregion *)region{  [self.locationmanager stoprangingbeaconsinregion:self.beaconregion]; }    -(void) locationmanager:(cllocationmanager *)manager didrangebeacons:(nsarray *)beacons   inregion:(clbeaconregion *)region {   checkdidenterbusstop=yes;   uilocalnotification *notification = [[uilocalnotification alloc]init]; notification.alertbody = @"you have reached bus stop"; notification.soundname = uilocalnotificationdefaultsoundname;  [[uiapplication sharedapplication] presentlocalnotificationnow:notification];  }      - (void)didreceivememorywarning { [super didreceivememorywarning]; // dispose of resources can recreated. }      @end 

can me out pointing out mistakes. thanks

you need notify tableview data has changed - call

[tableview reloaddata]  

in didrangebeacons method - call numberofrowsinsection again
