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
}
}
}
实际上我们正在做的是如果section只有一行然后我们在所有方面都这样做,如果section有多行,那么我们在第一行顶部和最后一行底部执行...属性BottomLeft,BottomRight, topLeft,TopRight应该是rect corner类型(当您输入时来自xcode的建议......还有另一个具有相同名称的属性内容角..所以检查一下)

您可以在swift 2.0中使用以下代码
将此代码放在cellForRowAtIndexpath方法中:
cell!.layer.cornerRadius=10 //set corner radius here
cell!.layer.borderColor = UIColor.blackColor().CGColor // set cell border color here
cell!.layer.borderWidth = 2 // set border width here
以下是我的代码的输出
答案 2 :(得分:3)
您的tableView似乎包含UIView
,因此只需在cellForRowAtIndexPath
中添加这些行即可。如果没有添加UIView并将半径添加到UIView,只需将该视图添加到您的单元格(cell.addSubView(YOURVIEW)
)。
cell.contentView.layer.cornerRadius = 10
cell.contentView.layer.masksToBounds = true
要自定义边框
cell.layer.borderColor = UIColor.grayColor().CGColor
cell.layer.borderWidth = 5
<强>更新强>
要在viewForHeaderInSection
中添加此内容
创建一个视图,让view = UIView()并将半径添加到视图中
view.layer.cornerRadius = 10
view.layer.masksToBounds = true
添加您需要的其他属性并返回该视图。
