[swift]使用Storyboard的情況下,設定App的第一頁

• 方法一:打開Storyboard移動起始指標,指到的Controller預設就會用那個ViewController為起始頁面
  

• 方法二:
  先對在Storyboard的Controller設定Storyboard ID
  

  然後找到AppDelegate.swift檔案改寫didFinishLaunchingWithOptions ```swift
  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { let storyboard = UIStoryboard(name:”Main” , bundle: nil);
  self.window? = UIWindow(frame: UIScreen.mainScreen().bounds);
  //指定Storyboard ID
  self.window?.rootViewController = storyboard.instantiateViewControllerWithIdentifier(“testa”) as? UIViewController;
  self.window?.makeKeyAndVisible();
  return true
  }
