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

为所有单元格添加背景(使用Maciej的答案):

for (int section = 0; section < [self.tableView numberOfSections]; section++) {
        for (int row = 0; row < [self.tableView numberOfRowsInSection:section]; row++) {
            NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
            UITableViewCell* cell = [self.tableView cellForRowAtIndexPath:cellPath];

            //stuff to do with each cell
            UIView *bgColorView = [[UIView alloc] init];
            bgColorView.backgroundColor = [UIColor redColor];
            [cell setSelectedBackgroundView:bgColorView];
        }
    } 

Swift 3:对我来说，当你把它放在cellForRowAtIndexPath:方法中时，它就工作了

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

我想指出的是，XIB编辑器为您提供了以下标准选项:

部分:蓝色/灰色/没有

(右边有选项的列，第4个标签，第一组“表格视图单元格”，第4个子组，3个项目中的第一个读为“选择”)

也许你想做的事情可以通过选择正确的标准选项来实现。

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。
