通讯录

通讯录(按照两种不同的cell,按性别区分)

在ViewController.swift中键入:

在Main.storyboard中Editor->Embed in->Navigation Controller添加导航栏

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

import UIKit

class WomanTableViewCell: UITableViewCell {

        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state

}

command+n 创建一个Cocoa Touch Class 名为ManTableViewCell.swift

创建第二个ViewController名为SecondViewController

    //如果是更新传递过来一个对象
    var person:Person!=nil

    // 更新的闭包  1. p  2. 多少组,多少行
    var UpdateBlock: ((Person,IndexPath)->Void)? = nil
    
    // 添加的闭包 1. p
    var AddPersonBlock:((Person)->Void)? = nil

        self.btn?.addTarget(self, action: #selector(btnAction), for: .touchUpInside)
        self.btn?.setTitle("保存", for: .normal)
        self.view.addSubview(self.btn!)

        self.view.addSubview(self.groupTextField!)
        //判断更新还是添加
        if self.operate == .Add { // 添加操作
            self.btn.setTitle("添加", for:.normal)
        } else { // 更新操作, 需要给textfield赋值
            self.btn.setTitle("更新", for: .normal)
            self.nameTextField.text = person.name
            self.phoneTextField.text = person.phoneNumber
            var str = ""
            str.append(person.group)
            self.groupTextField.text = str
            self.img.text = person.img
            // 性别
            if person.gender == .Girl {
                self.genderTextField.text = "女"
            } else {
                self.genderTextField.text = "男"
            }
            
        }
        
    }

    func btnAction(){

        p.img = "person"
        
        if self.operate == .Add { // 添加
            self.AddPersonBlock!(p)
