Instead of reloading the entire UITableView you could try just using insertRowsAtIndexPaths. It doesn't reload all the cells and gives you a nice animation on top of it.

For example:

-(void)addData:(NSString *)text{

    //provided your self.greekLetter is NSMutableArray 

    [self.greekLetter addObject:text]

    NSIndexPath *index = [NSIndexPath indexPathForRow:(self.greekLetter.count - 1) inSection:0];

    [self.tableview insertRowsAtIndexPaths:@[index] withRowAnimation:UITableViewRowAnimationRight];
}

Assuming that your greekLetter is NSMutableArray:

-(void) addDataToGreekLetter {
    [self.greekLetter addObject:@"TestObject"];
    [self.tableView reloadData];
}

Assuming that your greekLetter is NSArray:

-(void) addDataToGreekLetter {
    NSMutableArray *temp = [NSMutableArray arrayWithArray: self.greekLetter];
    [temp addObject:@"TestObject"];
    self.greekLetter = [NSArray arrayWithArray:temp];
    [self.tableView reloadData];
}
