RN APP 打开通知权限

在React Native中，开启通知权限需要使用原生代码。以下是针对iOS和Android的示例代码。

iOS

在AppDelegate.m中添加以下代码：

#import <UserNotifications/UserNotifications.h>
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if (@available(iOS 10.0, *)) {
        [UNUserNotificationCenter requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        }];
    } else {
        // Fallback on earlier versions
    }
    return YES;
}

Android

在MainActivity.java中添加以下代码：

import android.content.Intent;
import android.os.Bundle;
import androidx.core.app.NotificationManagerCompat;
import android.widget.Toast;
 
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactInstanceManager;
 
public class MainActivity extends ReactActivity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
 
    @Override
    protected String getMainComponentName() {
        return "YourAppName";
    }
 
    @Override
    protected ReactInstanceManager createReactInstanceManager() {
        ReactInstanceManager instanceManager = super.createReactInstanceManager();
        instanceManager.addReactInstanceEventListener(instanceManager);
        return instanceManager;
    }
 
    // Check and request permissions
    public void requestNotificationPermissions() {
        if (NotificationManagerCompat.from(this).areNotificationsEnabled()) {
            // Notifications are enabled for this app
        } else {
            // Notifications are disabled for this app
            // You can either navigate the user to the settings page, or show an in-app dialog explaining why you need notifications enabled
            Intent intent = new Intent();
            intent.setAction("android.settings.APP_NOTIFICATION_SETTINGS");
            intent.putExtra("app_package", getPackageName());
            intent.
