Swift3 从后台返回后强制启动应用程序。斯威夫特3

当我打开应用程序，转到后台，最后返回前台时，我的界面出现了一些问题。所以当我从后台回来时，我想强制我的应用程序始终启动应用程序。 我看到皇家冲锋队的比赛就是这样的。

我正在使用swift 3开发我不知道您从后台返回后希望加载的主页是什么样子，但您应该能够使用AppDelegate中的函数，以便能够在从后台返回时根据需要设置值和加载场景或视图，或者能够设置所需的当应用程序关闭时查看

下面是已内置到AppDelegate中的函数列表

func applicationWillResignActive(_ application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}

func applicationDidEnterBackground(_ application: UIApplication) {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(_ application: UIApplication) {
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(_ application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

func applicationWillTerminate(_ application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

由于某些原因，applicationWillResignActive未格式化为代码。很抱歉，谢谢你修好了@LeoDabus。由于某种原因，它不接受我的编辑。你试过了吗？
