代号一个本地通知不适用于ios

Question

I have added a local notifications so when my app gets a push while opening there is still a popup and a sound. It's working fine on Android, but on iOS the local notification doesn't appear at all.

The push notifications are working fine on both platforms.

This is my code in the push callback that should trigger the notification (if the app is open):

if(Display.getInstance().getCurrent() != null) {
    LocalNotification n = new LocalNotification();
    n.setId(value);
    n.setAlertBody(value);
    n.setAlertTitle({app name});
    n.setBadgeNumber(1);
    Display.getInstance().scheduleLocalNotification(n, System.currentTimeMillis() + 1000, LocalNotification.REPEAT_NONE);
}

Answer 1

Local notifications don't fire while the app is open in the foreground. You should use a different mechanism to make a sound while the app is running. Eg Display.vibrate()

Answer 2

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

[[NSNotificationCenter defaultCenter] postNotificationName:@"DriverNotification" object:nil userInfo:userInfo];
//    [[NSNotificationCenter defaultCenter] postNotificationName:@"UserNotification" object:nil userInfo:userInfo];
       NSLog(@"%@",userInfo);
}

Put This Code in Your View Controller

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(receiveNotification:) name:@"DriverNotification" object:nil
 ];

Did you call registerUserNotificationSettings to register the fact that your app uses local notifications? If you don't do that, your request to post a local notification will be ignored.

See this text from the description of that method:

If your app displays alerts, play sounds, or badges its icon, you must call this method during your launch cycle to request permission to alert the user in these ways. (You must also make this request if you want to set the applicationIconBadgeNumber property directly.) Typically, you make this request if your app uses local or remote notifications to alert the user to new information involving your app. The first time your app launches and calls this method, the system asks the user whether your app should be allowed to deliver notifications and stores the response. Thereafter, the system uses the stored response to determine the actual types of notifications you may use.

After calling this method, the app calls the application:didRegisterUserNotificationSettings: method of its app delegate to report the results. You can use that method to determine if your request was granted or denied by the user.

It is recommended that you call this method before you schedule any local notifications or register with the push notification service. Calling this method with a new user settings object replaces the previous settings request. Apps that support custom actions must include all of their supported actions in the notificationSettings object.

you need to add below code in didFinishLaunchingWithOptions method of AppDelegate.m file for register local notification

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
        if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)])
        {
            [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        }
        else
        {
            [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
             (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
        }
}
