代理实现

EmptyDataSource

extension Test_TVc:EmptyDataSource{
    /**

     - Parameter scrollView: 目标视图
     
     - Returns: 副标题（描述）
     
     */
    func description(emptyView scrollView: UIScrollView) -> NSAttributedString? {
        var attributes: [NSAttributedStringKey:Any] = [:]
        attributes[NSAttributedStringKey.font] = UIFont.systemFont(ofSize: 17)
        attributes[NSAttributedStringKey.foregroundColor] = UIColor.red
        let paragraph = NSMutableParagraphStyle()
        paragraph.alignment = .center
        attributes[NSAttributedStringKey.paragraphStyle] = paragraph
        let attributedString =  NSMutableAttributedString(string: "商品列表数据为空啊", attributes: nil)
        let range = (attributedString.string as NSString).range(of: "列表数据")
        attributedString.addAttributes([NSAttributedStringKey.foregroundColor: #colorLiteral(red: 0, green: 0.6784313725, blue: 0.9450980392, alpha: 1)], range: range)
        return attributedString
    }
}

     func didTap(emptyView scrollView: UIScrollView, button: UIButton){
        
    }
}
