Ios 如何在AppDelegate中扩展UNUserNotificationCenterDelegate协议？

我正在开发一个React本机应用程序，它使用两个不同的库来处理本地通知（

React本机社区/推送通知ios

）和远程推送通知（Leanplum）。Leanplum SDK使用swizzling。不幸的是，即使我禁用swizzling，建议的显示前台通知的设置也会阻止正确处理远程通知

我收到了远程通知SDK支持团队的一条反馈

您在本地级别的实现正在干扰Leanplum swizzle。您是否能够实现用户通知委托协议，并在app delegate类中进行扩展？在iOS实现中，这允许两种逻辑（LP和local）自动且平滑地进行。我们建议AppDelegate实现扩展UnuseNotificationCenterDelegate协议，特别是如果您希望保留本地推送实现

虽然我正在尽我最大的努力尽快学习Objective-C，但我不是本地的iOS开发人员，我不知道如何遵循这个建议。我已经阅读了很多关于设置推送通知的问题，但是他们都建议使用下面的设置，我还没有找到任何解决前台通知处理干扰另一个库的问题的方法

如何扩展AppDelegate中的

UNUserNotificationCenterDelegate

协议，以不干扰远程通知库的方式处理前台通知

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

  [...]
    
  // Define UNUserNotificationCenter
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  center.delegate = self; // <-- interferes with the remote notification SDK
  
  [RNSplashScreen show];
  return YES;
}

  [...]

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
    [RNCPushNotificationIOS didReceiveRemoteNotification:userInfo fetchCompletionHandler:completionHandler];
    // Needs to be called if swizzling is disabled in Info.plist otherwise it won’t affect SDK if swizzling is enabled.
    [Leanplum didReceiveRemoteNotification:userInfo

fetchCompletionHandler:completionHandler];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    // Needs to be called if swizzling is disabled in Info.plist otherwise it won’t affect SDK if swizzling is enabled.
    [RNCPushNotificationIOS didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
    [Leanplum didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    [RNCPushNotificationIOS didFailToRegisterForRemoteNotificationsWithError:error];
    // Needs to be called if swizzling is disabled in Info.plist otherwise it won’t affect SDK if swizzling is enabled.
    [Leanplum didFailToRegisterForRemoteNotificationsWithError:error];
}

// Required for localNotification event
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void (^)(void))completionHandler
{
  [RNCPushNotificationIOS didReceiveNotificationResponse:response];
}

//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
  completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge);
}

-（BOOL）应用程序：（UIApplication*）应用程序使用选项完成启动：（NSDictionary*）启动选项
{
[...]
//定义未使用的通知中心
UNUserNotificationCenter*中心=[UNUserNotificationCenter currentNotificationCenter]；
center.delegate=self；//我也遇到了同样的问题，但我发现在停用swizzling时不再调用某些深层代码

将此添加到文件的顶部

#导入

替换

-（void）用户通知中心：（UNUserNotificationCenter*）中心将使用completionHandler:（void（^）（UNNotificationPresentationOptions））completionHandler显示通知：（UNNotification*）通知
{
完成处理程序（UNNotificationPresentationOptionSound | UnnotificationPresentationOptionErt | UNNotificationPresentationOptionBadge）；
}

为此：

-（void）用户通知中心：（UNUserNotificationCenter*）中心将使用completionHandler:（void（^）（UNNotificationPresentationOptions））completionHandler显示通知：（UNNotification*）通知
{
[[LPPushNotificationsManager sharedManager].handler将显示通知：带有completionHandler:completionHandler的通知]；
}
我也面临同样的问题，但我发现在停用swizzling时不再调用某些深层代码

-（void）用户通知中心：（UNUserNotificationCenter*）中心将使用completionHandler:（void（^）（UNNotificationPresentationOptions））completionHandler显示通知：（UNNotification*）通知
{

}

为此：

-（void）用户通知中心：（UNUserNotificationCenter*）中心将使用completionHandler:（void（^）（UNNotificationPresentationOptions））completionHandler显示通知：（UNNotification*）通知
{
[[LPPushNotificationsManager sharedManager].handler将显示通知：带有completionHandler:completionHandler的通知]；
}

// Define UNUserNotificationCenter
  UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
  center.delegate = self; // <-- interferes with the remote notification SDK

...

//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler
{
  completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge);
