推送通知不显示

Question

I've added functionality for receiving remote notifications yet the behaviour is really weird. When the application is in a foreground, the method

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

is being called. Although when the app is in the background — nothing shows up. I do not see the banner with incoming notification's message and nothing appears in Notifications swipe down list.

One more weird thing — the application doesn't show up in device's Settings --> Notification apps list. Is it ok that I receive them at all? Even if it is only when in the background?

Has anyone faced similar issues?

Answer 1

When your app is open, the didReceiveRemoteNotification method will be called in your app delegate, but an alert will not be shown. The alert is only shown when your app is in background/inactive. You can though create a UIAlertView in your app easily enough and show it when the app is active and a push notification is received.

Solved that stuff myself finally — I didn't call registerUserNotificationSettings , so no types of notifications were allowed. Now I do this:

[application registerForRemoteNotifications];
UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[application registerUserNotificationSettings:mySettings];

Works perfectly!
