控制器:
-主視圖控制器(TabBarViewController)
-訪客視圖控制器(UITableViewController)
-歡迎視圖控制器(UIViewController)
-OAthen授權(quán)視圖控制器(UIViewController)
-子視圖控制器(UITableViewController)
邏輯關(guān)系:
未登錄狀態(tài)下打開App--->訪客視圖
訪客視圖點(diǎn)擊登錄按鈕-->OAthen授權(quán)界面
OAthen授權(quán)后-->歡迎視圖控制器(dismiss OAthen控制器時(shí)發(fā)布通知,切換根控制器)
歡迎視圖控制器結(jié)束-->主控制器(動畫結(jié)束后歡迎視圖控制器再次發(fā)布通知,切換根控制器)
主控制器下的子控制器繼承自訪客視圖控制器,訪客視圖控制器通過是否登錄標(biāo)識判斷顯示登錄或未登錄視圖界面
AppDelegate中代碼示例:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//設(shè)置主題顏色

//設(shè)置window

//設(shè)置背景色
window?.backgroundColor = UIColor.whiteColor()
//設(shè)置根控制器
setupRootViewController()
//設(shè)置主窗口并顯示
window?.makeKeyAndVisible()
//監(jiān)聽通知
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(changeRootViewController(_:)), name: "changeTootViewControllerNotification", object: nil)
return true
}
//設(shè)置根控制器
func setupRootViewController() -> Void {
if JSUserAccountTools.sharedTools.isLogin {
//如果用戶已登錄,根控制器是歡迎界面
window?.rootViewController = JSWelcomeViewController()
}else {
//如果用戶未登錄,根控制器是訪客界面
window?.rootViewController = JSTabBarController()
}
}
//切換根控制器

將訪客視圖UI搭建抽取為單獨(dú)一個(gè)類,并提供對外修改UI的方法

將OAthen授權(quán)獲得的數(shù)據(jù),存放到一個(gè)單例類中,同時(shí)做本地化處理,并存放是否登錄的標(biāo)識,防止每一次使用信息都對沙盒進(jìn)行操作

//判斷用戶是否登錄標(biāo)識
