如何给单个uitableview单元舍入边框

Question

我有一个UIviewController，在xib文件中添加了3个uitableview单元格，但是我想给顶部和底部的单元格圆角，类似于分组表的外观。 如何做到这一点，以及如何通过编程将表单元格添加到uiviewcontroller？

Answer 1

这是我的方法，但是要实现此目的，您需要具有顶部单元格，底部单元格和中间单元格的图像。 这将有助于区分第一行，中间行和最后一行。

    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;
