ios - 选择单元格时，UITableView 所有组件都更改了背景颜色

Question

我正在自定义 tableview 的单元格。该单元包含 2 个按钮(一个是红色的，另一个是蓝色的)。但是当我选择单元格时，2 个按钮的背景颜色更改为突出显示的单元格颜色。我希望它们在单元格突出显示时保持颜色。我的解决方案是捕获 tableview 的突出显示委托(delegate)并更改按钮的背景。

谁能给我另一种解决方案？

谢谢

您必须在 UITableViewCell 子类中重写 setHighlighted 和 setSelected

objective-c

-(void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated
{
    UIColor *someViewColor = self.someView.backgroundColor;
    [super setHighlighted:highlighted animated:animated];
    self.someView.backgroundColor = someViewColor;
}

-(void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    UIColor *someViewColor = self.someView.backgroundColor;
    [super setSelected:selected animated:animated];
    self.someView.backgroundColor = someViewColor;
}

swift

override func setHighlighted(highlighted: Bool, animated: Bool) {

    let someViewColor = someView.backgroundColor        
    super.setHighlighted(highlighted, animated: animated)
    someView.backgroundColor = someViewColor
}

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

    let someViewColor = someView.backgroundColor        
    super.setSelected(selected, animated: animated)
    someView.backgroundColor = someViewColor
}
