spritekit无法从后台状态获取打印

既然你用的是SpriteKit,我想应该是 state 你提供的电话正在 didMove(to:) GameScene.swift . 如果是这种情况,那么您没有遇到问题,而是遇到了所需的结果;当场景调用 滴漏(到:) 方法。

AppDelegate.swift :

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    print("app finished launching")
    return true
}

func applicationDidEnterBackground(_ application: UIApplication) {
    print("app in background")
}

func applicationWillEnterForeground(_ application: UIApplication) {
    print("app in foreground")
}
