关闭后自动重启 nativescript 8 angular 应用程序 - 退出或完成 - 该应用程序更改应用程序语言

Question

我正在我的 nativescript 8 angular 应用程序中实现 EddyVerbruggen/nativescript-localize 插件，我想知道是否有办法在 [=19] 退出后自动重启应用程序=] 或 android 中的结尾用于更改应用程序语言。

更准确地说，在 NS 官方文档 (https://docs.nativescript.org/plugins/localize.html#how-to-change-the-language-dynamically-at-runtime ) 中，我找到了这段代码（请参阅下面的警告...）我希望完成 ?????? （请参阅下面的代码）使用一种方法（如果可能的话）在关闭后重新启动应用程序。

import { Application } from '@nativescript/core'
import { overrideLocale } from '@nativescript/localize'

alert({
  title: 'Switch Language',
  message: 'The application needs to be restarted to change language',
  okButtonText: 'Quit!'
}).then(() => {
  L.localize.overrideLocale(selectedLang)
  if (isAndroid) {
    ;(
      Application.android.foregroundActivity || Application.android.startActivity
    ).finish()
    
    // Here I need a method to RESTART the app automatically after finsih
    ?????
  } else {
    exit(0)
    // Here I need a method to RESTART the app automatically after exit
    ?????
  }
})

要在 nativescript android 中重启应用程序，请使用：

if (isAndroid) {
    const Intent = android.content.Intent;
    type Intent = android.content.Intent;
    
    const IntentCompat = androidx.core.content.IntentCompat;
    type IntentCompat = androidx.core.content.IntentCompat;

    const ctx: android.content.Context = application.android.context;

    const mainIntent: Intent = IntentCompat.makeMainSelectorActivity(Intent.ACTION_MAIN, Intent.CATEGORY_LAUNCHER);
    mainIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    ctx.getApplicationContext().startActivity(mainIntent);
    (
        Application.android.foregroundActivity ||
        Application.android.startActivity
    ).finish();
}

对于iOS，您似乎无法重新启动应用程序，Apple 的建议甚至是不要使用exit() 以编程方式退出应用程序，您可以阅读here：

Warning: Do not call the exit function. Applications calling exit will appear to the user to have crashed, rather than performing a graceful termination and animating back to the Home screen.

但是，如果您仍想调用退出函数，则有重新启动应用程序的解决方法，例如安排在应用程序退出后显示本地通知（如 here). To do this using nativescript you can use NativeScript Local Notifications Plugin 使用以下代码所示：

import {
    LocalNotifications,
    NotificationAction
} from 'nativescript-local-notifications';

// inside your class:
private scheduleNotification() {
    var scheduledTime = new Date();
    scheduledTime.setSeconds(scheduledTime.getSeconds() + 30);
    
    const actionStartSession: NotificationAction = {
        id: 'startSession',
        type: 'button',
        title: 'Restart App',
        launch: true,
        choices: ['Restart']
    };

    // Check if we have permission on iOS
    LocalNotifications.hasPermission().then(granted => {
        if (granted) {
            console.log('We have permission to schedule notifications.');
        } else {
            LocalNotifications.requestPermission().then(granted => {
                alert(`This app needs permission to schedule notifications. Please go to iOS settings > hmapp > Notifications, and allow notifications.`);
            });
        }
    });

    LocalNotifications.schedule([
        {
            id: new Date().getTime(),
            title: 'App restart required',
            body: 'Tap to reopen the application',
            at: scheduledTime,
            actions: [actionStartSession]
        }
    ]).then(
        () => {
            console.log('Notification scheduled');
        },
        error => {
            console.log('Scheduling error: ' + error);
        }
    );
}
