保存解析通知 - iOS

Question

我希望在 UITableView 中发送所有通知。 因为用户可以在不启动应用程序的情况下删除通知（在通知中心），所以我必须将所有通知存储在 Parse 数据库中。

那么，如何以编程方式将发送的通知保存在数据库中。我不想发送通知，然后在数据库中手动输入通知。

希望很清楚。谢谢

这是在发送推送通知之前将推送通知保存到解析类的代码。

    PFObject *messageActivity = [PFObject objectWithClassName:kPAPActivityClassKey];
    [messageActivity setObject:kPAPActivityTypeReceivedMessage forKey:kPAPActivityTypeKey];
    [messageActivity setObject:[PFUser currentUser] forKey:kPAPActivityFromUserKey];
    [messageActivity setObject:self.user forKey:kPAPActivityToUserKey];
    [messageActivity setObject:textField.text forKey:kPAPActivityContentKey];

    PFACL *messageACL = [PFACL ACLWithUser:[PFUser currentUser]];
    [messageACL setPublicReadAccess:YES];
    [messageACL setWriteAccess:YES forUser:self.user];
    messageActivity.ACL = messageACL;

    // If more than 5 seconds pass since we post a comment, stop waiting for the server to respond
    NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:5.0f target:self selector:@selector(handleCommentTimeout:) userInfo:@{@"message": messageActivity} repeats:NO];

    [messageActivity save];
    [timer invalidate];

    PFObject *sentMessageActivity = [PFObject objectWithClassName:kPAPActivityClassKey];
    [sentMessageActivity setObject:kPAPActivityTypeSentMessage forKey:kPAPActivityTypeKey];
    [sentMessageActivity setObject:self.user forKey:kPAPActivityFromUserKey];
    [sentMessageActivity setObject:[PFUser currentUser] forKey:kPAPActivityToUserKey];
    [sentMessageActivity setObject:textField.text forKey:kPAPActivityContentKey];

    PFACL *sentMessageACL = [PFACL ACLWithUser:[PFUser currentUser]];
    [sentMessageACL setPublicReadAccess:YES];
    [sentMessageACL setWriteAccess:YES forUser:[PFUser currentUser]];
    sentMessageActivity.ACL = sentMessageACL;

    [sentMessageActivity save];


    //even if the message is not saved to log, still send the message
    //ideally should just add this text message activity to the log and the rest of the notification system should send out a notification but since we don't have a centralized place to insert to activity/log, we have to duplicate code here
    // Create our Installation query
    PFQuery *pushQuery = [PFInstallation query];
    [pushQuery whereKey:@"UserObjectId" equalTo:self.user.objectId];
    // Send push notification to query
    [PFPush sendPushMessageToQueryInBackground:pushQuery
                                   withMessage:[[[@"From " stringByAppendingString:[[PFUser currentUser] objectForKey:@"displayName"]] stringByAppendingString:@": " ] stringByAppendingString:textField.text]
     ];
