学习笔记---Swift通讯录

1. AppDelegate.swift

加个导航控制器

window?.rootViewController = UINavigationController(rootViewController: ViewController())

2.ViewContr0ller.swift

2.1懒加载BarButton

  lazy var addBtn:UIBarButtonItem = {
        let btn = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Add, target: self, action: "action")
        return btn
    }()

2.2懒加载TableView

    lazy var tab:UITableView = {
    let tv = UITableView(frame: UIScreen.mainScreen().bounds, style: UITableViewStyle.Plain)
        tv.delegate = self
        tv.dataSource = self
        return tv
    }()

2.3在ViewDidLoad中先添加几个联系人

 for i in 0..<10
        {
            let contact = Contact(name: "Iphone\(i)", age: "9.\(i)", gender: "♀", phone: "110-911\(i)")
            ContactManager.shareContactManager.addContact(contact)
        }

2.4设置属性

        view.backgroundColor = UIColor.whiteColor()
//注册cell
        tab.registerNib(UINib(nibName: "ContactCell", bundle:   NSBundle.mainBundle()), forCellReuseIdentifier: "ss")
        view.addSubview(tab)        
        navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Add, target: self, action: "addAction")
//实现方法
  func addAction(){
        let add = addViewController()
        add.closure = {
            ()->()
            in
            self.tab.reloadData()
            }
      navigationController?.pushViewController(add, animated: true)
    }

2.5将协议写在类的延展里

//extension 本类名:协议名{ }
extension ViewController:UITableViewDelegate,UITableViewDataSource{    
         func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) ->  UITableViewCell {
        let cell = tab.dequeueReusableCellWithIdentifier("ss", forIndexPath: indexPath) as! ContactCell//强转
         let contact = ContactManager.shareContactManager.contactArray[indexPath.row]
         cell.cellWithContact(contact)
         return cell
    }
    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
           return ContactManager.shareContactManager.contactArray.count
    }
     func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        return 110
    }
      func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {      
//     let storyBoard = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
//     let detailVC = storyBoard.instantiateViewControllerWithIdentifier("") as! MyViewController        
        let vc = MyViewController()
        let contact = ContactManager.shareContactManager.contactArray[indexPath.row]
        vc.creat(contact)
        navigationController?.pushViewController(vc, animated: true)
    }    
        func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) ->   Bool {
           return true
          }
        func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == .Delete{
        ContactManager.shareContactManager.removeContactByIndexPath(indexPath)
         tab.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Top)
        }
 }

3.添加页面addViewController.swift

3.1声明闭包和关联四个控件

    var closure:(()->())?
    @IBOutlet var nameLabel: UITextField!  
    @IBOutlet var genderLabel: UITextField!
    @IBOutlet var ageLabel: UITextField!  
    @IBOutlet var phoneLabel: UITextField!

3.2实现添加联系人

@IBAction func BtnAction(sender: UIButton) {
 let contact = Contact(name: nameLabel.text!, age: ageLabel.text!, gender: phoneLabel.text!,  phone: phoneLabel.text!)     
ContactManager.shareContactManager.contactArray.append(contact)
 closure!()    
navigationController?.popViewControllerAnimated(true)        
 }

4 自定义ContactCell.swift

    @IBOutlet var nameLabel: UILabel!  
    @IBOutlet var ageLabel: UILabel!
    @IBOutlet var genderLabel: UILabel!
    @IBOutlet var phoneLabel: UILabel!
    //根据contact给cell里面的标签赋值
    func cellWithContact(contact:Contact){
        nameLabel.text = contact.name
        ageLabel.text = contact.age
        genderLabel.text = contact.gender
        phoneLabel.text = contact.phone
    }

5.详情页面MyViewController.swift

//拖四个lab控件
    @IBOutlet var nameLabel: UILabel!    
    @IBOutlet var genderLabel: UILabel!
    @IBOutlet var ageLabel: UILabel!
    @IBOutlet var phoneLabel: UILabel!
//声明四个属性
    var name:String?
    var age:String?
    var gender:String?
    var phone:String?
//定义个model函数方便传值
    func creat(contact:Contact){
        name = contact.name
        age = contact.age
        gender = contact.gender
        phone = contact.phone
}
//  在ViewDidload里面进行赋值
        nameLabel.text = name
        genderLabel.text = gender
        ageLabel.text = age
        phoneLabel.text = phone

6.创建单例类ContactManager.swift

6.1 将联系人管理类声明为单例类,管理所有联系人的操作,增删改查

   static let shareContactManager:ContactManager = {
        let contactManager = ContactManager()
        return contactManager
    }()

6.2 所有联系人的数组

    var contactArray:[Contact] = [Contact]()
    func addContact(contact:Contact){
          contactArray.append(contact)
    }

6.3 移除联系人

    func removeContactByIndexPath(indexpath:NSIndexPath){
        contactArray.removeAtIndex(indexpath.row)
    }
