如何在didFinishLaunchingWithOptions中調用API。並在響應後啓動所有執行

Question

我想在第一次啓動應用程序時在AppDelegate類didFinishLaunchingWithOptions中調用API，並在響應後啓動所有執行。

Answer 1

我想你想做一個網絡調用（例如檢查應用程序版本），等待一個響應，然後基於響應，從右側的視圖啓動應用程序。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    let startupVC = // Create a temporary view controller in Storyboard or XIB (can be the same as your launch view controller) 
     self.window.rootViewController = starupVC 
    self.window.makeKeyAndVisible() 

    networkCallWithReponseBlock { 
     let startingViewController = // your view controller from Storyboard, XIB or code 
      self.window.rootViewController = startingViewController 
    } 
    return true 
}
