TableView 点击空白放弃焦点

拦截响应事件

extension UITableView {
    open override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        let view = super.hitTest(point, with: event)

        // give up first response
        if let v = view ,(v.isKind(of: UITextField.self) || v.isKind(of: UITextView.self)){
            return v
        }
        self.endEditing(true)
        
        return view
    }
}

(v.isKind(of: UITextField.self) || v.isKind(of: UITextView.self) 这句有待商榷
