Notification Center gets called but value of UILabel is not updated in IOS

I am using push notifications in my code and whenever a notification comes, I want to update the value of a label in another ViewController.

My code in AppDelegate is:

- (void)addMessageFromRemoteNotification:(NSDictionary*)userInfo updateUI:(BOOL)updateUI
{
    NSLog(@"Notification arrived");
    //[mydeals setCode1_id:mydeals.code1_id withString:@"123456"];
    mydeals=[[MyDealsViewController alloc]init];
    NSDictionary* codeDetails=[[NSDictionary alloc] initWithObjectsAndKeys:@"123456",@"Code_id", nil];
    [[NSNotificationCenter defaultCenter] postNotificationName:@"CodeArrived" object:self userInfo:codeDetails];
}

then in my other view controller I have this code:

@implementation MyDealsViewController

-(id) init
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(receiveCode:)
                                                 name:@"CodeArrived"
                                               object:nil];
    return self;
}

-(void) receiveCode:(NSNotification*)notification
{
    NSLog(@"received Code: %@",notification.userInfo);
    self.code1_id.text=[NSString stringWithFormat:@"%@",[[notification userInfo] valueForKey:@"Code_id"]];
}

the log is printed correctly but when I manually go into that screen I see the default value, like the label is not updated at all. What should I do?

You might also try calling [self.code1_id setNeedsLayout];

You have to make sure that when you "manually go" to MyDealsViewController, whatever how you do it, it got to be the same instance of MyDealsViewController wich has been called receiveCode. Otherwise it's going to init with it's default values.
