推荐答案

您有两个选择:

1. 在故事板中创建您的 UIView
2. 以编程方式创建

选项 2

1. 创建您的 UIView.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? 
    let headerView = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.width, height: 30.0))        

    // Button1
    let button1 = UIButton(frame: CGRect(x: 15.0, y: 0, width: 100, height: 28.0)
    button1.setTitle("Button 1", for: .normal)
    button1.addTarget(self, action: #selector(selectorButton1), for: .touchUpInside)

    // Button2
    let button2 = UIButton(frame: CGRect(x: tableView.frame.width-150, y: 0, width: 150, height: 30.0))
    button2.setTitle("Button2", for: .normal)
    button2.addTarget(self, action: #selector(selectorButton2), for: .touchUpInside)
    button2.semanticContentAttribute = UIApplication.shared
        .userInterfaceLayoutDirection == .rightToLeft ? .forceLeftToRight : .forceRightToLeft

    headerView.addSubview(button1)
    headerView.addSubview(button2)
    return headerView 
}


    @objc func selectorButton1(_ sender : Any) {

    }

    @objc func selectorButton2(_ sender : Any) {

    }

在这种情况下，您必须在创建UIView(frame: CGRect())和时正确设置y和x位置UIButton(frame: CGRect())

In this case, you must set correctely y and x positions when create UIView(frame: CGRect()) and UIButton(frame: CGRect())

编辑

从您的代码中，您只需要添加目标:

From your code, you just need add the targets:

selectAllBtn.addTarget(self, action: #selector(selectorAllBtn), for: .touchUpInside)
sendButton.addTarget(self, action: #selector(selectorSendButton), for: .touchUpInside)

@objc func selectorAllBtn(_ sender : Any) {

}

@objc func selectorSendButton(_ sender : Any) {

}
