* Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSMutableArray removeObjectsAtIndexes:]: index 5 in index set beyond bounds [0 .. 4]'

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return mAryValue.count; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString * strIdent=@"id1Cell"; UITableViewCell * cell=[tableView dequeueReusableCellWithIdentifier:strIdent]; if (cell==nil) { cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strIdent]; } cell.textLabel.text=[mAryValue objectAtIndex:indexPath.row]; return cell; } - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleDelete; } -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (self.editing) { return; } [_tblView deselectRowAtIndexPath:[_tblView indexPathForSelectedRow] animated:NO]; UITableViewCell *cell = [_tblView cellForRowAtIndexPath:indexPath]; if (cell.accessoryType == UITableViewCellAccessoryNone) { cell.accessoryType = UITableViewCellAccessoryCheckmark; [mArySel addObject:indexPath]; } else if(cell.accessoryType == UITableViewCellAccessoryCheckmark) { cell.accessoryType = UITableViewCellAccessoryNone; [mArySel removeObjectIdenticalTo:indexPath]; } } -(void)getData:(NSMutableArray *)userValues { mAryValue=userValues; } - (IBAction)btnDelete:(id)sender { if (mAryValue==nil || mAryValue.count==0) { UIAlertController * alert= [UIAlertController alertControllerWithTitle:@"Alert" message:@"Please Enter Value" preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; [alert addAction:ok]; [alert addAction:cancel]; [self presentViewController:alert animated:YES completion:nil]; } else { NSMutableIndexSet *indicesToDelete = [[NSMutableIndexSet alloc] init]; for (NSIndexPath *indexPath in mArySel) { [indicesToDelete addIndex:indexPath.row]; } if (!(indicesToDelete==nil) || !(indicesToDelete.count==0)) { [mAryValue removeObjectsAtIndexes:indicesToDelete]; } [_tblView reloadData]; } }
