控制器:
-主视图控制器(TabBarViewController)
-访客视图控制器(UITableViewController)
-欢迎视图控制器(UIViewController)
-OAthen授权视图控制器(UIViewController)
-子视图控制器(UITableViewController)
逻辑关系:
未登录状态下打开App--->访客视图
访客视图点击登录按钮-->OAthen授权界面
OAthen授权后-->欢迎视图控制器(dismiss OAthen控制器时发布通知,切换根控制器)
欢迎视图控制器结束-->主控制器(动画结束后欢迎视图控制器再次发布通知,切换根控制器)
主控制器下的子控制器继承自访客视图控制器,访客视图控制器通过是否登录标识判断显示登录或未登录视图界面
AppDelegate中代码示例:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//设置主题颜色
setThemeColor()
//设置window
window = UIWindow(frame: UIScreen.mainScreen().bounds)
//设置背景色
window?.backgroundColor = UIColor.whiteColor()
//设置根控制器
setupRootViewController()
//设置主窗口并显示
window?.makeKeyAndVisible()
//监听通知
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(changeRootViewController(_:)), name: "changeTootViewControllerNotification", object: nil)
return true
}
//设置根控制器
func setupRootViewController() -> Void {
if JSUserAccountTools.sharedTools.isLogin {
//如果用户已登录,根控制器是欢迎界面
window?.rootViewController = JSWelcomeViewController()
}else {
//如果用户未登录,根控制器是访客界面
window?.rootViewController = JSTabBarController()
}
}
//切换根控制器
func changeRootViewController(notic: NSNotification) -> Void {
if notic.object == nil {
window?.rootViewController = JSWelcomeViewController()
}else {
window?.rootViewController = JSTabBarController()
}
}
private func setThemeColor() -> Void{
UITabBar.appearance().tintColor = THEMECOLOR
UINavigationBar.appearance().tintColor = THEMECOLOR
}
deinit{
//移除监听对象
NSNotificationCenter.defaultCenter().removeObserver(self)
}
欢迎视图控制器代码:

img.clipsToBounds = true
img.sd_setImageWithURL(NSURL(string: JSUserAccountTools.sharedTools.userAccount?.avatar_large ?? ""), placeholderImage: UIImage(named: "avatar_default_big"))
return img
}()
private lazy var messageLabel: UILabel = {
let lab = UILabel()
lab.alpha = 0.01
lab.text = "欢迎回来"
lab.font = UIFont.systemFontOfSize(18)
lab.textColor = UIColor.grayColor()
lab.textAlignment = NSTextAlignment.Center
return lab

OAthen视图控制器代码:

import SVProgressHUD
import AFNetworking
class JSOAuthViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
//设置导航栏按钮
setupNav()
}
// MARK: - 设置导航栏按钮

//请求数据

访客视图控制器:
class JSVistorTableViewController: UITableViewController {
//标识用户是否登录
let isLogin: Bool = JSUserAccountTools.sharedTools.isLogin
//VistorView
var vistorView: JSVistorView?
override func loadView() {
if isLogin {
//已登录
super.loadView()
}else{
//未登录
setupVistorView()
}
}
// MARK: - 设置导航栏
private func setupNav()-> Void{
navigationItem.leftBarButtonItem = UIBarButtonItem(title: "登录", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(loginClick))
navigationItem.rightBarButtonItem = UIBarButtonItem(title: "注册", style: UIBarButtonItemStyle.Plain, target: self, action: #selector(loginClick))
}
// MARK: - 导航栏按钮点击事件
@objc private func loginClick() -> Void {
let oauthVc = JSOAuthViewController()
let naVC = JSNavigationController(rootViewController: oauthVc)
presentViewController(naVC, animated: true, completion: nil)
}
// MARK: - 设置访客视图
private func setupVistorView() -> Void {
vistorView = JSVistorView()
view = vistorView
vistorView?.closure = {[weak self] in
self?.loginClick()
}
//设置导航栏按钮
setupNav()
}
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
将访客视图UI搭建抽取为单独一个类,并提供对外修改UI的方法
// MARK: - 供外界调用的方法,修改视图信息
func setupVistorViewInfo(imgName: String?,title: String?) -> Void {
if let img = imgName,let tit = title {
//非主页
centerImageView.image = UIImage(named: img)
messageLabel.text = tit
feedImageView.removeFromSuperview()
}else{
//主页:设置动画
setupAnim()
}
}
将OAthen授权获得的数据,存放到一个单例类中,同时做本地化处理,并存放是否登录的标识,防止每一次使用信息都对沙盒进行操作
class JSUserAccountTools: NSObject {
//全局访问点
static let sharedTools: JSUserAccountTools = JSUserAccountTools()
var userAccount: JSUserAccountModel?
var accessToken: String?{
if userAccount?.access_token == nil {
//如果访问令牌为nil,代表未登录,返回nil
return nil
}else {
if userAccount?.expires_Date?.compare(NSDate()) == NSComparisonResult.OrderedDescending {
//访问令牌不为nil,与当前时间比较为降序,未过期,代表登录
return userAccount?.access_token
}else {
//如果访问令牌不为nil,但是时间过期,代表未登录
return nil
}
}
}
//判断用户是否登录标识
var isLogin: Bool {
//如果access_token为nil,代表没登录(如果accessToken为nil,代表isLogin = false)
return accessToken != nil
}
override init() {
super.init()
userAccount = getUserAccount()
}
let path = (NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true).last! as NSString).stringByAppendingPathComponent("userAccount.archiver")
//保存对象
func saveUserAccount(userAccount userAcc: JSUserAccountModel) -> Void {
self.userAccount = userAcc
//归档
NSKeyedArchiver.archiveRootObject(userAcc, toFile: path)
}
//获取对象
func getUserAccount() -> JSUserAccountModel? {
//解档
let userAccount = NSKeyedUnarchiver.unarchiveObjectWithFile(path) as? JSUserAccountModel
return userAccount
}
}
