1.在AppDelegate檔案中新增如下程式碼
import UIKit @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { window=UIWindow(frame:UIScreen.main.bounds) window?.rootViewController = RedViewController() //通過修改這句話決定程式第一次停留的頁面,此處為紅色頁面(.storyboard) //window?.rootViewController = BlueViewController(nibName:"BlueViewController",bundle:nil) //通過修改這句話決定程式第一次停留的頁面,此處為藍色頁面(.xib) window?.makeKeyAndVisible() return true } }
