iOS local notification userInfo always null - ios

Question

I am trying to schedule a local notification with some custom data attached which I will then read when the user opens the app by clicking on the notification.
I schedule the local notification like this:
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.fireDate = [[NSDate date] dateByAddingTimeInterval:10];
notification.alertBody = #"Hello World!";
notification.userInfo = [[NSDictionary alloc] initWithObjectsAndKeys:
#"123123123123", #"beaconUUID",
[NSNumber numberWithInt:10], #"beaconMajor",
[NSNumber numberWithInt:20], #"beaconMinor",
nil];
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
Then in the code which handles the notification I do this:
- (void)onAppDidBecomeActive:(NSNotification*)notification
{
NSLog(#"Object = %#", [notification object]);
NSDictionary* userInfo = [notification userInfo];
NSLog(#"UserInfo = %#", userInfo);
NSString* beaconUUID = [userInfo objectForKey:#"beaconUUID"];
NSLog(#"Beacon UUID = %#", beaconUUID);
}
My problem is that when I try to read the userInfo it always returns null. How do I read the userInfo dictionary from a NSNotification object?
The three NSLog calls from the above code sample print the following in the console:
2015-02-04 14:11:52.690 BeaconPlugin[17050:724150] Object = <UIConcreteLocalNotification: 0x7ff1d37199a0>{
fire date = Wednesday, February 4, 2015 at 2:11:51 PM Central European Standard Time,
time zone = (null),
repeat interval = 0,
repeat count = UILocalNotificationInfiniteRepeatCount,
next fire date = (null),
user info = {
beaconMajor = 10;
beaconMinor = 20;
beaconUUID = 123123123123;
}}
2015-02-04 14:11:52.691 BeaconPlugin[17050:724150] UserInfo = (null)
2015-02-04 14:11:52.691 BeaconPlugin[17050:724150] Beacon UUID = (null)
Which does show that the dictionary values are part of the user info. Anybody got any ideas what I am doing wrong?

Answer 1

You scheduled a UILocalNotification but you are retrieving your user info from a NSNotification, this two is not the same.
you should do this:
UILocalNotification *localNotif = [notification object];
NSDictionary *userInfo = [localNotif userInfo];
NSString* beaconUUID = [userInfo objectForKey:#"beaconUUID"];

Answer 2

Its worked for when i receive from didReceiveLocalNotification protocol
in AppDelegate.m file
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
UIApplicationState state = [application applicationState];
NSLog(#"Object = %#", notification);
NSDictionary* userInfo = [notification userInfo];
NSLog(#"UserInfo = %#", userInfo);
NSString* beaconUUID = [[notification userInfo] objectForKey:#"beaconUUID"];
NSLog(#"Beacon UUID = %#", beaconUUID);
}
see below output console
2015-02-04 19:11:12.937 SampleNO[6676:907] Object = <UIConcreteLocalNotification: 0x769e780>{fire date = Wednesday, February 4, 2015, 7:11:09 PM India Standard Time, time zone = (null), repeat interval = 0, repeat count = UILocalNotificationInfiniteRepeatCount, next fire date = (null), user info = {
beaconMajor = 10;
beaconMinor = 20;
beaconUUID = 123123123123;
}}
