问题描述

我有一个小问题，我想像下面的图片一样更改单元格的拐角半径

I have small problem , I want to change cell corner radius like below image

推荐答案

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath)
{
if (tableView == self.orderDetailsTableView)
{
    //Top Left Right Corners
    let maskPathTop = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.TopLeft, .TopRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
    let shapeLayerTop = CAShapeLayer()
    shapeLayerTop.frame = cell.bounds
    shapeLayerTop.path = maskPathTop.CGPath

    //Bottom Left Right Corners
    let maskPathBottom = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.BottomLeft, .BottomRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
    let shapeLayerBottom = CAShapeLayer()
    shapeLayerBottom.frame = cell.bounds
    shapeLayerBottom.path = maskPathBottom.CGPath

    //All Corners
    let maskPathAll = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.TopLeft, .TopRight, .BottomRight, .BottomLeft], cornerRadii: CGSize(width: 5.0, height: 5.0))
    let shapeLayerAll = CAShapeLayer()
    shapeLayerAll.frame = cell.bounds
    shapeLayerAll.path = maskPathAll.CGPath

    if (indexPath.row == 0 && indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1)
    {
        cell.layer.mask = shapeLayerAll
    }
 else if (indexPath.row == 0)
    {
    cell.layer.mask = shapeLayerTop
    }
    else if (indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1)
    {
        cell.layer.mask = shapeLayerBottom
    }
}
}

实际上，我们要做的是，如果节只有一行，那么我们在所有面上都做，如果节有多行，那么我们将它放在第一行的顶部，最后一行的底部...属性BottomLeft，BottomRight，topLeft，TopRight的类型应为rect corner(键入时来自xcode的建议...还有另一个具有相同名称的属性内容corner ..因此请检查)

what actually we are doing is if section has only one row then we do it on all sides, if section has multiple rows then we do it top on first row and bottom at last row... the properties BottomLeft, BottomRight, topLeft, TopRight should be of type rect corner(Suggestions from xcode when you are typing... there is another property content corner with same name.. so check that )
