In-App purchase Issue : Purchase not persist

I am trying to enable a In built function through a non consumable purchase. I could retrieve my product and make a purchase but I got a issue in persisting the purchase. When I purchase the product,my button (disabled initially) in view controller has to be enabled and also I kept a label changing its name "purchased".After purchase my label text changes and button enabled, but when I stop and run back Xcode the label state only persists not my button it goes back to disabled state.

** view controller **

-(void)Purchased {
    Label.text = @"item has been purchased";
  _newview.enabled=YES;
   NSUserDefaults *saveapp = [NSUserDefaults standardUserDefaults];
   [saveapp setBool:TRUE forKey:k_Save];
    [saveapp synchronize];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSUserDefaults *saveapp = [NSUserDefaults standardUserDefaults];
    bool saved = [saveapp boolForKey:k_Save];
    if (!saved) {
        /// not save code here

    NSLog(@"wooo");
    } else {
        ///saved code here
        Label.text = @"item has been purchased";
    }
    // Do any additional setup after loading the view, typically from a nib.
}

** purchased view controller **

-(void)UnlockPurchase {

    _buyButton.enabled = NO;
    [_buyButton setTitle:@"Purchased" forState:UIControlStateDisabled];
    [_homeViewController Purchased];
}

I called this "UnlockPurchase" in updated transactions delegate function. Now the worst case here is after purchase this "_buyButton" state gets back soon to enabled.

Is this steps correct or wrong ? How to make the purchase to persist ? Please help !

try to put the same code (to enable the button) in your viewDidLoad method, too…

…

bool saved = [saveapp boolForKey:k_Save];
….
} else {
        ///saved code here
        Label.text = @"item has been purchased”;

       //Disable BuyButton
       //Enable your DesiredButton

    }

UPD

add SKPaymentTransactionStateRestored to your method:

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
    for (SKPaymentTransaction *transaction in transactions) {

...  
case SKPaymentTransactionStateRestored:[self UnlockPurchase];                
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
....
