ios-无法在已终止的应用程序中接收json推送通知

Question

但是当我通过两次点击home按钮并滑动应用程序来终止应用程序时，就不会收到json通知。（换句话说，方法“应用程序：DidReceiverEmoteNotification：”未调用）。

我使用NSLog代码来检查通知接收和监视设备CONSOL。

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo{
      NSLog(@"Receive notification in didReceiveRemoteNotification %@", userInfo);
}

我在stackoverflow的帖子中看到了所有类似的问题，但没有找到答案。

当你的应用程序在后台远程通知接收，但“Application：DidReceiverEmoteNotification：”没有调用对吗？

启用后台模式(&P)

在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                         categories:nil];
[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];
  // Extract the notification data
NSDictionary *notificationPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
}
