[iOS개발] FCM foreground에서 앱푸시 띄우기

// AppDelegate.h

UserNotifications을 import하고 인터페이스에 UNUserNotificationCenterDelegate를 추가한다

#import <React/RCTBridgeDelegate.h>
#import <UIKit/UIKit.h>
#import <Firebase.h>
#import <UserNotifications/UserNotifications.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate> 

@property (nonatomic, strong) UIWindow *window;

@end

 

// AppDelegate.mm

파이어베이스 설정 초기화 후에 delegate를 등록하는 코드 추가

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//  [FIRApp configure];
  
  // Add me --- \/
    if ([FIRApp defaultApp] == nil) {
      [FIRApp configure];
    }
    // Add me --- /\
    
    (...)
    [self initializeRemoteNotification];

	(...)
    
 }

#pragma mark - Initialize Remote Notification
- (void)initializeRemoteNotification {
    
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        
    
}

그리고 마찬가지로 AppDelegate.mm에 아래 소스를 추가한다.

 

// Receive displayed notifications for iOS 10 devices.
// Handle incoming notification messages while app is in the foreground.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
       willPresentNotification:(UNNotification *)notification
         withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {
  NSDictionary *userInfo = notification.request.content.userInfo;

  // With swizzling disabled you must let Messaging know about the message, for Analytics
  // [[FIRMessaging messaging] appDidReceiveMessage:userInfo];

  // ...

  // Print full message.
  NSLog(@"%@", userInfo); 
  

  // Change this to your preferred presentation option
  completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound);
}

// Handle notification messages after display notification is tapped by the user.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
         withCompletionHandler:(void(^)(void))completionHandler {
  NSDictionary *userInfo = response.notification.request.content.userInfo;
  if (userInfo) {
    NSLog(@"Message ID: %@", userInfo);
  }

  // With swizzling disabled you must let Messaging know about the message, for Analytics
  // [[FIRMessaging messaging] appDidReceiveMessage:userInfo];

  // Print full message.
  NSLog(@"%@", userInfo);

  completionHandler();
}

핸들러 param에는 원하는 프레젠테이션 옵션을 넣어주면 된다 (배너,배지,사운드)

  completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound);

 

 

위와같이 코드를 추가해주면 알람을 받았을 때 앱 실행상태에서도 푸시가 표시되는 걸 확인할 수 있다.
