iphone - 如何给一个单独的uitableview单元格圆形边框

Question

我有一个 UIviewController，在 xib 文件中我添加了 3 个 uitableview 单元格，但我想给顶部和底部单元格提供类似于分组表外观的圆角。我该如何做到这一点，以及如何以编程方式将表格单元格添加到 uiviewcontroller？

Answer 1

这是我的方法，但要使其工作，您需要有顶部单元格、底部单元格和中间单元格的图像。这将有助于区分第一行、中间行和底部行。

    UIImage *rowBackground;
    UIImage *selectionBackground;
    NSInteger sectionRows = [tableView numberOfRowsInSection:[indexPath section]];
    if (indexPath.row == 0)
    {
        rowBackground = [UIImage imageNamed:@"topRow.png"]; //Top Rounded
        selectionBackground = [UIImage imageNamed:@"topRowSelected.png"]; //Top Rounded Selected
    }
    else if (indexPath.row == sectionRows - 1)
    {
        if (indexPath.section == 0) {
        rowBackground = [UIImage imageNamed:@"bottomRow.png"];// Bottom Rounded
        selectionBackground = [UIImage imageNamed:@"bottomRowSelected.png"]; //Bottom Rounded Selected
        } else {
            rowBackground = [UIImage imageNamed:@"bottomRowSelected.png"];
            selectionBackground = [UIImage imageNamed:@"bottomRow.png"];
        }
    }
    else
    {
        rowBackground = [UIImage imageNamed:@"middleRow.png"]; // Anything in the middle
        selectionBackground = [UIImage imageNamed:@"middleRowSelected.png"];
    }

    ((UIImageView *)cell.backgroundView).image = rowBackground;
    ((UIImageView *)cell.selectedBackgroundView).image = selectionBackground;
