丰富的推送通知不适用于 IOS 中的 FCM

Question

我在我的项目中添加了UNNotificationServiceExtension 和UNNotificationContentExtension 用于丰富的推送通知。
请参考下面我添加的相同代码。

代码：

#import "NotificationService.h"

@interface NotificationService ()

@property (nonatomic, strong) void (^contentHandler)(UNNotificationContent *contentToDeliver);
@property (nonatomic, strong) UNMutableNotificationContent *bestAttemptContent;

@end

@implementation NotificationService {
    NSURLSession *session;
}

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {

    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];
    NSDictionary *userInfo = request.content.userInfo;
    if (userInfo == nil) {
        [self contentComplete];
        return;
    }

    if ([userInfo objectForKey:@"pic_url"]) {
        [self loadAttachmentForUrlString:[userInfo objectForKey:@"pic_url"]
                       completionHandler: ^(UNNotificationAttachment *attachment) {
                           self.bestAttemptContent.attachments = [NSArray arrayWithObjects:attachment, nil];
                       }];
    }
}

- (void)loadAttachmentForUrlString:(NSString *)urlString
                 completionHandler:(void (^)(UNNotificationAttachment *))completionHandler
{
    __block UNNotificationAttachment *attachment = nil;
    __block NSURL *attachmentURL = [NSURL URLWithString:urlString];

    NSString *fileExt = [@"." stringByAppendingString:[urlString pathExtension]];


    session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

    NSURLSessionDownloadTask *task = [session downloadTaskWithURL:attachmentURL
                                                completionHandler: ^(NSURL *temporaryFileLocation, NSURLResponse *response, NSError *error) {
                                                    if (error != nil)
                                                    {
                                                        NSLog(@"%@", error.localizedDescription);
                                                    }
                                                    else
                                                    {
                                                        NSFileManager *fileManager = [NSFileManager defaultManager];
                                                        NSURL *localURL = [NSURL fileURLWithPath:[temporaryFileLocation.path
                                                                                                  stringByAppendingString:fileExt]];
                                                        [fileManager moveItemAtURL:temporaryFileLocation
                                                                             toURL:localURL
                                                                             error:&error];

                                                        NSError *attachmentError = nil;
                                                        attachment = [UNNotificationAttachment attachmentWithIdentifier:[attachmentURL lastPathComponent]
                                                                                                                    URL:localURL
                                                                                                                options:nil
                                                                                                                  error:&attachmentError];
                                                        if (attachmentError)
                                                        {
                                                            NSLog(@"%@", attachmentError.localizedDescription);
                                                        }
                                                    }
                                                    completionHandler(attachment);
                                                }];

    [task resume];
}

- (void)serviceExtensionTimeWillExpire {
    // Called just before the extension will be terminated by the system.
    // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
    [self contentComplete];
}

- (void)contentComplete
{
    [session invalidateAndCancel];
    self.contentHandler(self.bestAttemptContent);
}

@end

我正在使用以下有效负载

    {
   "to": "9yJUWBA",
   "mutable_content": true,
   "category": "myNotificationCategory",
   "notification":
   {                                               
      "title":"Realtime Custom Push Notifications",
       "subtitle":"Now with iOS 10 support!",
       "body":"Add multimedia content to your notifications"
   }
}

问题是我没有收到通知。我使用以下教程来实现丰富的推送通知。我检查了可用的不同答案，但没有一个对我有用。我还尝试通过附加扩展进程来调试 didReceiveNotificationRequest 方法，但没有触发断点。

Answer 1

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{

    //Called when a notification is delivered to a foreground app.
    NSLog(@"Userinfo willPresentNotification%@",notification.request.content.userInfo);

    // Print message ID.
    /*
     NSDictionary *userInfo = notification.request.content.userInfo;
     if (userInfo[kGCMMessageIDKey]) {
     NSLog(@"Message ID: %@", userInfo[kGCMMessageIDKey]);
     }
     */


    completionHandler(UNNotificationPresentationOptionAlert);

}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{

    //Called to let your app know which action was selected by the user for a given notification.
    NSLog(@"Userinfo didReceiveNotificationResponse%@",response.notification.request.content.userInfo);

    // Print message ID.
    /*
     NSDictionary *userInfo = notification.request.content.userInfo;
     if (userInfo[kGCMMessageIDKey]) {
     NSLog(@"Message ID: %@", userInfo[kGCMMessageIDKey]);
     }
     */


}

使用上述方法，这些方法适用于 iOS 10 及更高版本。 如需调试通知服务扩展，请访问以下链接

Debug Notification Extensions

如果您从 iOS 9 开始支持您的应用程序，那么您必须将以下两种方法都用于 iOS 10 以上，并且您还在问题中写道

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{

    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // [[FIRMessaging messaging] appDidReceiveMessage:userInfo];
    /*
     // Print message ID.
     if (userInfo[kGCMMessageIDKey]) {
     NSLog(@"Message ID: %@", userInfo[kGCMMessageIDKey]);
     }
     */
    // Print full message.
    NSLog(@"Userinfo didReceiveRemoteNotification 1 %@",userInfo);


}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

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

    /*
     // Print message ID.
     if (userInfo[kGCMMessageIDKey]) {
     NSLog(@"Message ID: %@", userInfo[kGCMMessageIDKey]);
     }
     */
    // Print full message.

    NSLog(@"Userinfo didReceiveRemoteNotification 2 %@",userInfo);


    completionHandler(UIBackgroundFetchResultNewData);
}

如果您有任何疑问，请告诉我。
