Swift 5 - Xcode版本12.1 (12A7403)

| |第一步 将以下内容添加到AppDelegate.swift文件中

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

    let colorView = UIView()
    colorView.backgroundColor = UIColor.lightGray

    UITableViewCell.appearance().selectedBackgroundView = colorView
        
    return true
}

|第二步| 确保在属性检查器中，单元格的内容视图背景设置为“清除颜色”(而不是“默认”)。这样做是为了不与App Delegate设置冲突。

在Swift 4中，你还可以全局设置你表格单元格的背景色(从这里取):

let backgroundColorView = UIView()
backgroundColorView.backgroundColor = UIColor.red
UITableViewCell.appearance().selectedBackgroundView = backgroundColorView

以下是我在iOS 8中使用的。

我必须将选择样式设置为UITableViewCellSelectionStyleDefault，以便自定义背景色能够工作。如果有其他样式，自定义背景色将被忽略。在行为上似乎有一个变化，因为以前的答案需要将style设置为none。

单元格的完整代码如下:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"MyCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    // This is how you change the background color
    cell.selectionStyle = UITableViewCellSelectionStyleDefault;
    UIView *bgColorView = [[UIView alloc] init];
    bgColorView.backgroundColor = [UIColor redColor];
    [cell setSelectedBackgroundView:bgColorView];        
    return cell;
}

快4.倍

要改变选择背景颜色为任何颜色使用Swift扩展

创建UITableView Cell扩展，如下所示

extension UITableViewCell{

    func removeCellSelectionColour(){
        let clearView = UIView()
        clearView.backgroundColor = UIColor.clear
        UITableViewCell.appearance().selectedBackgroundView = clearView
    } 

}

然后用单元格实例调用removeCellSelectionColour()。

下面是分组表所需的代码的重要部分。当一个部分中的任何单元格被选中时，第一行将改变颜色。如果没有最初设置cellselectionstyle为none，当用户单击row0时，单元格更改为bgColorView，然后淡入并重新加载bgColorView时，会出现恼人的双重重载。祝你好运，如果有更简单的方法，请告诉我。

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

    if ([indexPath row] == 0) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIView *bgColorView = [[UIView alloc] init];
        bgColorView.layer.cornerRadius = 7;
        bgColorView.layer.masksToBounds = YES;
        [bgColorView setBackgroundColor:[UIColor colorWithRed:.85 green:0 blue:0 alpha:1]];
        [cell setSelectedBackgroundView:bgColorView];

        UIColor *backColor = [UIColor colorWithRed:0 green:0 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithWhite:1 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row0";
    }
    else if ([indexPath row] == 1) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row1";
    }
    else if ([indexPath row] == 2) 
    {
        cell.selectionStyle = UITableViewCellSelectionStyleNone;

        UIColor *backColor = [UIColor colorWithRed:1 green:1 blue:1 alpha:1];
        cell.backgroundColor = backColor;
        UIColor *foreColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1];
        cell.textLabel.textColor = foreColor;

        cell.textLabel.text = @"row2";
    }
    return cell;
}

#pragma mark Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSIndexPath *path = [NSIndexPath indexPathForRow:0 inSection:[indexPath section]];
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:path];
    [cell setSelectionStyle:UITableViewCellSelectionStyleBlue];

    [tableView selectRowAtIndexPath:path animated:YES scrollPosition:UITableViewScrollPositionNone];

}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tvStat cellForRowAtIndexPath:indexPath];
    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}

#pragma mark Table view Gestures

-(IBAction)singleTapFrom:(UIGestureRecognizer *)tapRecog
{

    CGPoint tapLoc = [tapRecog locationInView:tvStat];
    NSIndexPath *tapPath = [tvStat indexPathForRowAtPoint:tapLoc];

    NSIndexPath *seleRow = [tvStat indexPathForSelectedRow];
    if([seleRow section] != [tapPath section])
        [self tableView:tvStat didDeselectRowAtIndexPath:seleRow];
    else if (seleRow == nil )
        {}
    else if([seleRow section] == [tapPath section] || [seleRow length] != 0)
        return;

    if(!tapPath)
        [self.view endEditing:YES];

    [self tableView:tvStat didSelectRowAtIndexPath:tapPath];
}

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
