ios - 当应用程序未运行时处理 JSON 推送通知解析

Question

我在处理使用 parse.com 发送的推送消息时遇到问题，当应用程序运行时，我可以处理 json 并使用以下命令构造消息:

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

但是当应用程序处于后台或被杀死时，此消息会被处理并直接发送到通知栏。我试图在这个函数中处理:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
....
 UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (localNotif) {

        [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 99];
        UIAlertView *BOOM = [[UIAlertView alloc] initWithTitle:@"BOOM"
                                                       message:@"app was INACTIVE"
                                                      delegate:self
                                             cancelButtonTitle:@"a-ha!"
                                             otherButtonTitles:nil];
        [BOOM show];
        NSLog(@"App was NOT ACTIVE");
    }
.....

est 这个响应，但我无法处理推送消息:

Handling Push Notifications when App is NOT running

Can't handle push notifications when app is running background

Handling push notifications when app is not running (App is Killed)

how can I handle push notification when my app is not running

有什么帮助吗？谢谢。

当应用程序未运行或在后台时，我无法处理通知，我改变了分辨率的焦点，我正在像 android 应用程序那样做，但我 iOS 用“消息控制”处理消息，我没有找到处理的“方法”这。

我开始使用 channel 订阅消息的推送通知取决于用户设置。我通过 channel 和应用订阅 channel 发送到 Parse 消息。

您可以通过 POST 发送通知:

  curl -X POST \
  -H "X-Parse-Application-Id: {APP-KEY}" \
  -H "X-Parse-REST-API-Key:   {REST-API-KEY}" \
  -H "Content-Type: application/json" \
  -d '{
        "channels": [
          "valencia",
          "sevilla"
        ],
        "data": {
          "alert": "Fin del partido Betis - Valencia 0-2",
          "sound": "gol.mp3"
        }
      }' \
  https://api.parse.com/1/push

在 App 中您可以订阅 AppDelegate 中的 channel :

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken {
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:newDeviceToken];

    NSArray * channels = @[@"channel1", @"channel2"];
    NSLog(@"Channels : %@", channels);
    currentInstallation.channels = channels;
    [currentInstallation saveInBackground];
}

您可以在任何地方更改 channel ，如下所示:

PFInstallation *currentInstallation = [PFInstallation currentInstallation];
currentInstallation.channels = @[@"channel3"];

[currentInstallation saveInBackground];

也许这可以帮助某人。
