我已经创建了一个自定义UITableViewCell。表视图很好地显示了数据。我陷入的是当用户触摸tableview的单元格时,然后我想显示单元格的背景颜色,而不是默认的[蓝色]值,以突出显示单元格的选择。 我使用这段代码,但什么都没有发生:

cell.selectedBackgroundView.backgroundColor=[UIColor blackColor];

试试下面的代码。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[cellIdArray objectAtIndex:indexPath.row] forIndexPath:indexPath];

    // Configure the cell...
    cell.backgroundView =
    [[UIImageView alloc] init] ;
    cell.selectedBackgroundView =[[UIImageView alloc] init];

    UIImage *rowBackground;
    UIImage *selectionBackground;


    rowBackground = [UIImage imageNamed:@"cellBackgroundDarkGrey.png"];
    selectionBackground = [UIImage imageNamed:@"selectedMenu.png"];

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



    return cell;
}

/ /快速版:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        let cell = tableView.dequeueReusableCell(withIdentifier: "cell")! as UITableViewCell


        cell.selectedBackgroundView = UIImageView()
        cell.backgroundView=UIImageView()

        let selectedBackground : UIImageView = cell.selectedBackgroundView as! UIImageView
        selectedBackground.image = UIImage.init(named:"selected.png");

        let backGround : UIImageView = cell.backgroundView as! UIImageView
        backGround.image = UIImage.init(named:"defaultimage.png");

        return cell


    } 

其他回答

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIView *view = [[UIView alloc] init];
    [view setBackgroundColor:[UIColor redColor]];
    [cell setSelectedBackgroundView:view];
}

我们需要在这个方法中设置所选的背景视图。

我使用下面的方法,对我来说很好,

class MyTableViewCell : UITableViewCell {

                var defaultStateColor:UIColor?
                var hitStateColor:UIColor?

                 override func awakeFromNib(){
                     super.awakeFromNib()
                     self.selectionStyle = .None
                 }

// if you are overriding init you should set selectionStyle = .None

                override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let hitColor = hitStateColor {
                        self.contentView.backgroundColor = hitColor
                    }
                }

                override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }

                override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
                    if let defaultColor = defaultStateColor {
                        self.contentView.backgroundColor = defaultColor
                    }
                }
            }

1-添加一个视图到单元格的内容视图。 2-右击你的单元格。 3-使添加的视图为“selectedBackgroundView”

单元格选择的背景颜色可以通过界面构建器中的Storyboard设置:

不需要自定义单元格。如果你只想改变单元格的选定颜色,你可以这样做:

objective - c:

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

迅速:

let bgColorView = UIView()
bgColorView.backgroundColor = UIColor.red
cell.selectedBackgroundView = bgColorView
