1.将日期选择器区域设置为中文（默认显示英文）      

datapicker.locale = NSLocale(localeIdentifier: "zh_CN") as Locale

2.

let slider = heightNumber.value

        let i = Int(slider)

        height.text = "\(i)厘米"

3.

let segmentedControl = segmentedControl.selectedSegmentIndex==0 ? "高富帅" : "白富美"

let switch = switch.isOn ? "有房" : "没房"

根据日期选择器计算年龄

        let gregorian = NSCalendar(calendarIdentifier: NSCalendar.Identifier.gregorian)

        let now = NSDate()

        let components = gregorian?.components([.year], from: age.date, to: now as Date, options: NSCalendar.Options(rawValue: 0))

        let ages = components?.year

        result.text = "姓名：\(name.text!),性别：\(segmentedControl),年龄：\(ages!)岁,身高：\(height.text!),\(switch)"

4.修改键盘的return类型（xib或者纯代码），键盘消失

name.delegate = self

func textFieldShouldReturn(_ textField: UITextField) -> Bool {

      textField.resignFirstResponder()

        return true
