3-Token+界面切换副本

  • AFN添加网络指示器
  • 设置缓存大小 NSURLCache
    只缓存get datatask
  • 发送用户名密码后 返回用户token、过期日期 创建模型接收
    发送accesstoken和uid 获取用户列表
 //2.是回调地址,截取code
    //query是回调URL 问号后面的所有字符串
    if let query = request.URL!.query where query.hasPrefix("code=") {
        let code = query.substringFromIndex("code=".endIndex)
        print(code)
        //发送请求 获取accesstoken
        NetworkingTools.sharedTools.loadAccessToken(code).subscribeNext({ (result) -> Void in
            print(result)
            //成功获得accesstoken 和uid
            //通过accesstoken和uid 获取用户数据列表
            NetworkingTools.sharedTools.loadUserInfo(result["access_token"]as!String, uid: result["uid"]as!String).subscribeNext({ (result) -> Void in
                //获得了用户信息 建立用户模型
                print(result)
                }, error: { (error) -> Void in
                    print(error)
            })
            }, error: { (error) -> Void in
                print(error)
            })
  • 设置过期日期
    didset

  • 通过uid获取用户头像(avatar)、昵称 并把属性加入用户模型中
    loaduserinfo

  • description

  • 用户模型归档
    遵守NSCoding

    func saveAccount(){
      let path = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).last
      NSKeyedArchiver.archiveRootObject(self, toFile: path!)
    }
    func encodeWithCoder(aCoder: NSCoder) {
      aCoder.encodeObject(access_token, forKey: "access_token")
      aCoder.encodeObject(uid, forKey: "uid")
      aCoder.encodeObject(name, forKey: "name")
      aCoder.encodeObject(avatar_large, forKey: "avatar_large")
    }
    required init?(coder aDecoder: NSCoder) {
      access_token = aDecoder.decodeObjectForKey("access_token")as?String
      uid = aDecoder.decodeObjectForKey("uid")as?String
      name = aDecoder.decodeObjectForKey("name")as?String
      avatar_large = aDecoder.decodeObjectForKey("avatar_large")as?String
    }
    
  • MVVM封装网络
    以前我们获取网络数据 都是在viewcontroller中进行,在MVVM中,viewcontroller不能直接访问模型数据,需要通过Viewmodel

  • 加载用户信息 判断过期
    在accountViewModel创建类方法 从沙盒中获取用户PLIST,判断是否有accesstoken

    private static var account:UserAccount?
    class func loadAccount()->UserAccount? {
      if account == nil{
          let path = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).last!.stringByAppendingString("/account.plist")
         account = NSKeyedUnarchiver.unarchiveObjectWithFile(path)as?UserAccount
          
      }
      return account
    }
    
  • 新特性
    创建nwefeatureController继承collectionViewController
    1.init 流水布局

    init(){
      super.init(collectionViewLayout: UICollectionViewFlowLayout())
    
    }
    

2.collectionView代理

  override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 4
  }
  override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier(DVCollectionCell, forIndexPath: indexPath)as!newFeatureCell
    
  //        cell.frame = view.bounds
    cell.imageIndex = indexPath.item
    cell.backgroundColor = (indexPath.row % 2==0) ? UIColor.redColor() : UIColor.grayColor()
    
    return cell
  }

3.注册cell

  private func setupUI(){
    let layout = collectionView?.collectionViewLayout as! UICollectionViewFlowLayout
    layout.itemSize = view.bounds.size
    layout.minimumInteritemSpacing = 0
    layout.minimumLineSpacing = 0
    layout.scrollDirection = UICollectionViewScrollDirection.Horizontal
    
    collectionView?.pagingEnabled = true
    collectionView?.bounces = false
    collectionView?.showsHorizontalScrollIndicator = false
  }
  • 自定义cell

    private class newFeatureCell : UICollectionViewCell{
    
     var imageIndex = 0{
     didSet{
         imageView.image = UIImage(named: "new_feature_\(imageIndex+1)")
         }
       }
       lazy var  imageView = UIImageView()
       override init(frame: CGRect) {
       super.init(frame: frame)
       addSubview(imageView)
       imageView.frame = bounds
     
     }
    
  • 显示登入按钮

    func showBTN(){
      button.hidden = false
      button.userInteractionEnabled = false
      button.transform = CGAffineTransformMakeScale(0, 0)
      
      UIView.animateWithDuration(1.2, delay: 0, usingSpringWithDamping: 0.8, initialSpringVelocity: 8, options: [], animations: { () -> Void in
          self.button.transform = CGAffineTransformIdentity
          }) { (_) -> Void in
       button.userInteractionEnabled = true
      }
    }
