贊和評論按鈕，然後保存它來解析

Question

有誰知道如何在tableview腳本下實現這些按鈕，然後保存它和retreive解析？

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section 
{ 
    NSString *cellidentifier=@"footer"; 
    UITableViewCell *footer = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    UIView* FView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 100.0)]; 
    UIButton *like = (UIButton *)[footer viewWithTag:1]; 
    [button addTarget:self action:@selector(buttonwastapped:) forControlEvents:UIControlEventTouchUpInside]; 
    [FView addSubview:self.like]; 
    return [FView autorelease]; 
} 

- (void)buttonwastapped:(UIButton*)sender 
    { 

    PFUser *user = [PFUser currentUser]; 
    PFRelation *relation = [user relationForKey:@"likes"]; 
    [relation addObject:post]; 
    [user saveInBackground]; 

} //i try to use that but nothing happened

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section 
{ 

    UIView* FView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 100.0)]; 
    UIButton *likeBtn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    likeBtn.frame = CGRectMake(0, 0, 30, 40); // set your btn frame 
    [likeBtn addTarget:self action:@selector(buttonwastapped:) forControlEvents:UIControlEventTouchUpInside]; 
    [FView addSubView:likeBtn]; 

    return [FView autorelease]; 
}
