这里是先定义一个button，然后在button里添加label视图，错开一定的位置

类似的问题都可以用类似的方法来实现

-(void)drawTitleLabel:(UITableViewCell *)cell withTitle:(NSString *)title withTag:(NSInteger)row

{  

    CLog(@"draw title ...");

    UIButton *btn = nil;

    btn =[UIButton buttonWithType:UIButtonTypeRoundedRect];

    btn.frame = CGRectMake(MARGIN_LEFT, BTN_MARGIN_HEIGHT, VIEW_WIDTH, BTN_HEIGHT);    

    btn.tag = row;

    [btn setBackgroundImage:[UIImage imageNamed:@"help_btn.png"] forState:UIControlStateNormal];

    [btn addTarget:self action:@selector(helpDataButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

    [cell addSubview:btn];

    

    UILabel *ttitleLabel = nil;

    ttitleLabel = [[[UILabel alloc]initWithFrame:CGRectMake(MARGIN_LEFT + 4, BTN_MARGIN_HEIGHT, VIEW_WIDTH - 4, BTN_HEIGHT)] autorelease];

    

    [ttitleLabel setBackgroundColor:[UIColor clearColor]];

    [ttitleLabel setFont:[UIFont systemFontOfSize:FONT_SIZE]];

    ttitleLabel.textColor = [UIColor blackColor];

    ttitleLabel.text = title;

    titleLabel.layer.borderColor = [UIColor clearColor].CGColor;

    [cell addSubview:ttitleLabel];

}
