Question

我正在尝试根据tableview的单元格向视图添加子视图..我已经完成了这段代码

  - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    VerseCell *cell = (VerseCell *)[tableView cellForRowAtIndexPath:indexPath];

    rowSelected = indexPath.row;

    CGRect  cellRect = cell.frame;

    UIView *cellView =[[UIView alloc]initWithFrame:CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70)];

  UIImageView* background =[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"FavoritePanelBackground"]];
    background.frame =CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70);
    [cellView addSubview:background];
    [cellView setBackgroundColor:[UIColor redColor] ];
    UIButton * favoritsB = [[UIButton alloc]initWithFrame:CGRectMake(cellRect.origin.x+10, cellRect.origin.y+15, 60, 40)];
    [favoritsB setBackgroundImage:[UIImage imageNamed:@"MofadalatNormalIcon.png"] forState:UIControlStateNormal];
    [favoritsB setBackgroundImage:[UIImage imageNamed:@"MofadalatTappedIcon.png"] forState:UIControlStateHighlighted];
  [favoritsB addTarget:self action:@selector(favorite) forControlEvents:UIControlEventTouchUpInside];

    [cellView addSubview:favoritsB];

    cellView=nil;

}

问题是..这个代码只在第一行中按预期工作..当点击下一个单元格时，它显示主要的UIVIew（我用红色背景标记）在预期位置，而子视图它的确走得很远......所以我在这里做错了..如果不行的话，我还在做什么呢？

你想在哪里添加这些视图？在表格视图单元格内？如果是这样，您永远不会将cellView添加为单元格的子视图。如果您正在尝试这样做，请在cellView = nil：

上方添加此行

[cell addSubview：cellView];

根据To UITableViewCell CGRect添加子视图
