如题，实现此效果需要重写cell的点击和高亮方法来保持子控件的背景颜色
代码如下：
colorViews：记录需要保持背景颜色的views，可在子控件初始化后添加

NSArray *colorViews;         ///< cell高亮或点击状态时需要保持背景颜色的views

- (void)setSelected:(BOOL)selected animated:(BOOL)animated{
    
    if (self.colorViews && self.colorViews.count > 0) {
        NSMutableArray *colors = [NSMutableArray array];
        NSMutableArray *views = [NSMutableArray array];
        
        for (UIView *view in self.colorViews) {
            if (view.backgroundColor && ![view.backgroundColor isEqual:[UIColor clearColor]]) {
                [colors addObject:view.backgroundColor];
                [views addObject:view];
            }
        }
        
        [super setSelected:selected animated:animated];
        
        for (NSInteger i = 0; i < colors.count; i ++) {
            UIView *view = [views objectAtIndex:i];
            UIColor *color = [colors objectAtIndex:i];
            
            [view setBackgroundColor:color];
        }
    }else{
        
        [super setSelected:selected animated:animated];
    }
    
}

- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated{
    
    
    if (self.colorViews && self.colorViews.count > 0) {
        NSMutableArray *colors = [NSMutableArray array];
        NSMutableArray *views = [NSMutableArray array];
        
        for (UIView *view in self.colorViews) {
            if (view.backgroundColor && ![view.backgroundColor isEqual:[UIColor clearColor]]) {
                [colors addObject:view.backgroundColor];
                [views addObject:view];
            }
        }
        
        [super setHighlighted:highlighted animated:animated];
        
        for (NSInteger i = 0; i < colors.count; i ++) {
            UIView *view = [views objectAtIndex:i];
            UIColor *color = [colors objectAtIndex:i];
            
            [view setBackgroundColor:color];
        }
    }else{
        [super setHighlighted:highlighted animated:animated];
    }
}
