command+n 创建一个Cocoa Touch Class 名为WomanTableViewCell.swift
import UIKit

self.btn = UIButton(type: .system)
self.btn?.frame = CGRect(x: 100, y: 500, width: 40, height: 30)
self.btn?.addTarget(self, action: #selector(btnAction), for: .touchUpInside)
self.btn?.setTitle("保存", for: .normal)
self.view.addSubview(self.btn!)

//判断更新还是添加
if self.operate == .Add { // 添加操作

// 性别
if person.gender == .Girl {
self.genderTextField.text = "女"
} else {

}
}
}
func btnAction(){
// 不管添加还是更新， 都需要根据textfield创建一个对象传递到第一个界面
let p = Person()
p.name = self.nameTextField.text

} else {

}

p.img = "person"
if self.operate == .Add { // 添加
self.AddPersonBlock!(p)
} else { //更新
self.UpdateBlock!(p,indexP!)
}
}
}
***运行结果如下图
