为UITableView设置三面边框 - IOS

Question

对于我的设计规范，我的表格视图在顶部，左侧和右侧应只有三个边框。我已经添加它使用下面的代码....

CGSize mainViewSize = menu_table.bounds.size; 
CGFloat borderWidth = 1; 
UIColor *borderColor = [UIColor lightGrayColor]; 
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, borderWidth, mainViewSize.height)]; 
UIView *rightView = [[UIView alloc] initWithFrame:CGRectMake(mainViewSize.width - borderWidth, 0, borderWidth, mainViewSize.height)]; 
UIView *topView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, mainViewSize.width, borderWidth)]; 
leftView.opaque = YES; 
rightView.opaque = YES; 
topView.opaque = YES; 
leftView.backgroundColor = borderColor; 
rightView.backgroundColor = borderColor; 
topView.backgroundColor = borderColor; 

// for bonus points, set the views' autoresizing mask so they'll stay with the edges: 
leftView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleRightMargin; 
rightView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin; 
topView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin; 

[menu_table addSubview:leftView]; 
[menu_table addSubview:rightView]; 
[menu_table addSubview:topView]; 

它工作正常，但是当我滚动表，子视图添加也向上移动。我不知道为什么子视图正在移动单元格，而是应该修复表，任何想法是什么问题，以及如何解决与表视图大小。感谢名单。

我不知道具体多少，但我能想到的最简单的方法是在你的tableview中添加3个contentviews象下面这样：

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease]; 
    //add left view 
    UIView *vwLeft=[[UIView alloc] initWithFrame:CGRectMake(X_POS, Y_POS, LINE_WIDTH, CELL_HEIGHT)]; 
    [vwLeft setBackgroundColor:[UIColor redColor]]; 
    [[cell contentView] addSubview:vwLeft]; 
    [vwLeft release]; 

    //add right view 
    UIView *vwRight=[[UIView alloc] initWithFrame:CGRectMake(X_POS, Y_POS, LINE_WIDTH, CELL_HEIGHT)]; 
    [vwRight setBackgroundColor:[UIColor blueColor]]; 
    [[cell contentView] addSubview:vwRight]; 
    [vwRight release]; 

    //add top view 
    UIView *vwTop=[[UIView alloc] initWithFrame:CGRectMake(X_POS, Y_POS, LINE_WIDTH, CELL_HEIGHT)]; 
    [vwTop setBackgroundColor:[UIColor yellowColor]]; 
    [[cell contentView] addSubview:vwTop]; 
    [vwTop release]; 

} 
return cell; 

}
