更改分组表视图中的选定单元格

Question

我创建了一个具有分组样式的静态单元格表​​视图

从上图中可以看出，我的问题是当我单击任何不对应于白色背景的单元格时会看到附件和不透明。有人可以帮我解决这个问题吗？

这是我实现部分圆角的代码。

 override func viewDidLoad() {
        self.tableView.separatorColor = UIColor.clearColor()
    }



    override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

        if (cell.respondsToSelector(Selector("tintColor"))){

            if (tableView == self.tableView) {

                let cornerRadius : CGFloat = 12.0
                cell.backgroundColor = UIColor.clearColor()
                let layer: CAShapeLayer = CAShapeLayer()
                let pathRef:CGMutablePathRef = CGPathCreateMutable()
                let bounds: CGRect = CGRectInset(cell.bounds, 25, 0)
                var addLine: Bool = false

                if (indexPath.row == 0 && indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1) {
                    CGPathAddRoundedRect(pathRef, nil, bounds, cornerRadius, cornerRadius)
                } else if (indexPath.row == 0) {
                    CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds))
                    CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds), CGRectGetMidX(bounds), CGRectGetMinY(bounds), cornerRadius)
                    CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius)
                    CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds))
                    addLine = true

                } else if (indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1) {
                    CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds))
                    CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds), CGRectGetMidX(bounds), CGRectGetMaxY(bounds), cornerRadius)
                    CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMaxY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius)
                    CGPathAddLineToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds))

                } else {
                    CGPathAddRect(pathRef, nil, bounds)
                    addLine = true

                }

                layer.path = pathRef
                layer.fillColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 0.8).CGColor

                if (addLine == true) {
                    let lineLayer: CALayer = CALayer()
                    let lineHeight: CGFloat = (1.0 / UIScreen.mainScreen().scale)
                    lineLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-lineHeight, bounds.size.width-10, lineHeight)
                    lineLayer.backgroundColor = tableView.separatorColor!.CGColor
                    layer.addSublayer(lineLayer)
                }

                let testView: UIView = UIView(frame: bounds)
                testView.layer.insertSublayer(layer, atIndex: 0)
                testView.backgroundColor = UIColor.clearColor()
                cell.backgroundView = testView
            }
        }

Answer 1

如果你只想改变单元格的选定颜色，你可以这样做：

目标-C：

UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor whiteColor];
[cell setSelectedBackgroundView:bgColorView];

斯威夫特：

var bgColorView = UIView()
bgColorView.backgroundColor = UIColor.whiteColor()
cell.selectedBackgroundView = bgColorView

对于单元格角轮：

cell.contentView.layer.cornerRadius = 5
cell.contentView.layer.masksToBounds = true 

Answer 2

你好洛佩兹，你所要做的就是禁用 UITableViewCell 上的选择样式

1) iOS cell.selectionStyle = UITableViewCellSelectionStyleNone; or [cell setAlpha:0.5];

2 斯威夫特 另一种方法可能是

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
carTableView?.deselectRowAtIndexPath(indexPath, animated: true)

}

快乐编程

随着您的实现，UITableViewCell 还有一个selectedBackgroundView 属性，因此您可以在方法末尾添加此代码。

我刚刚使用您创建的路径副本创建了另一个带有另一个 shapeLayer 的视图，更改了 fillColor 以指示选择。

        let selectedLayer = CAShapeLayer()
        selectedLayer.path = CGPathCreateCopy(pathRef)
        selectedLayer.fillColor = UIColor(white: 0.75, alpha: 0.8).CGColor
        let selectedView = UIView(frame: bounds)
        selectedView.layer.insertSublayer(selectedLayer, atIndex: 0)
        selectedView.backgroundColor = UIColor.clearColor()
        cell.selectedBackgroundView = selectedView
