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];

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
                    }
                }
            }

其他回答

override func setSelected(selected: Bool, animated: Bool) {
    // Configure the view for the selected state

    super.setSelected(selected, animated: animated)
    let selView = UIView()

    selView.backgroundColor = UIColor( red: 5/255, green: 159/255, blue:223/255, alpha: 1.0 )
    self.selectedBackgroundView = selView
}

Swift 3.0扩展

extension UITableViewCell {
    var selectionColor: UIColor {
        set {
            let view = UIView()
            view.backgroundColor = newValue
            self.selectedBackgroundView = view
        }
        get {
            return self.selectedBackgroundView?.backgroundColor ?? UIColor.clear
        }
    }
}

细胞。selectionColor = uiccolor . formacar .blue

当表视图样式是普通的,这很容易,但在组样式,这是一个小麻烦,我解决它:

CGFloat cellHeight = [self tableView:tableView heightForRowAtIndexPath:indexPath];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, kGroupTableViewCellWidth+2, cellHeight)];
view.backgroundColor = kCommonHighlightedColor;
cell.selectedBackgroundView = view;
[view release];
UIRectCorner cornerFlag = 0;
CGSize radii = CGSizeMake(0, 0);
NSInteger theLastRow = --> (yourDataSourceArray.count - 1);
if (indexPath.row == 0) {
    cornerFlag = UIRectCornerTopLeft | UIRectCornerTopRight;
    radii = CGSizeMake(10, 10);
} else if (indexPath.row == theLastRow) {
    cornerFlag = UIRectCornerBottomLeft | UIRectCornerBottomRight;
    radii = CGSizeMake(10, 10);
}
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds byRoundingCorners:cornerFlag cornerRadii:radii];
CAShapeLayer *shapeLayer = [CAShapeLayer layer];
shapeLayer.path = maskPath.CGPath;
view.layer.mask = shapeLayer;

注意到kGroupTableViewCellWidth,我把它定义为300,这是iPhone中组表视图单元格的宽度

根据UITableView中选定单元格的自定义颜色,根据Maciej Swic的答案,很棒的解决方案

为了补充这一点,你在Cell配置中声明Swic的答案通常如下:

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

为了增加效果,您可以使用RGB值来实现自定义颜色外观,而不是系统颜色。在我的代码中,我是这样实现的:

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

} 

 static NSString *CellIdentifier = @"YourCustomCellName";
 MakanTableCell *cell = [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

// Configure the cell...

if (cell == nil) {

cell = [[[NSBundle mainBundle]loadNibNamed:@"YourCustomCellClassName" owner:self options:nil]objectAtIndex:0];
                    } 

UIView *bgColorView = [[UIView alloc] init];
bgColorView.backgroundColor = [UIColor colorWithRed:255.0/256.0 green:239.0/256.0 blue:49.0/256.0 alpha:1];
bgColorView.layer.cornerRadius = 7;
bgColorView.layer.masksToBounds = YES;
[cell setSelectedBackgroundView:bgColorView];


return cell;

}

如果这对你也有用,请告诉我。你可以在选定单元格的角落上打乱拐角半径的数值。

覆盖UITableViewCell的setSelected也可以。

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Set background color
    let view = UIView()
    view.backgroundColor = UIColor.redColor()
    selectedBackgroundView = view
}
