in app purchase - present price to User

I have two View Controllers. One of them shows the available In App Purchases. When an user selects one of them it presents a new View Controllers containing the details of the Purchase and the "Buy" button.

The way I pass my code from the first view to the second is the following: 

-(IBAction)purchase1:(id)sender{
_purchasedController = [[iPadPurchasedViewController alloc] initWithNibName:nil bundle:nil];
_purchasedController.productID = @"xxxxx.xxxxx.xxxxx";
[self presentViewController:_purchasedController animated:YES completion:NULL];
[self.purchasedController getProductID:self];
}

So when a user selects one button I pass the productID string to the second ViewController. However, I wanted to present the price to the user on the first View Controller. Can somebody help me with that? Thank you.

Edited answer to be more complete:

In your ViewController.h file there should be 

@interface ViewController : UIViewController <SKProductsRequestDelegate> {
    NSArray *allProducts; 
}

Then in ViewController.m eg. in viewDidload:

-(void) viewDidload {
    [super viewDidLoad];
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObjects:@"xxxx1",@"xxxx2",nil]];
    request.delegate=self; 
    [request start]; 
}

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    allProducts = response.products;
    NSLog(@"Fetched %d products", allProducts.count);
 }

And then it can be used as such:

-(NSString*) getPriceForProductWithID:(NSString*)productID{

   if(allProducts.count < 1) {
        NSLog(@"Did not fetch products yet");
   }
   else {

       NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];
       numberFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
       [numberFormatter setNumberStyle:NSNumberFormatterCurrencyStyle];

       for(SKProduct * product in allProducts) {

           if([product.productIdentifier isEqualToString:productID])
           {
               [numberFormatter setLocale:product.priceLocale];

               NSString *priceString= [numberFormatter stringFromNumber:product.price];

        NSLog(@"Product with ID: %@ has price: %@",product.productIdentifier, priceString);
              return priceString;
           } 
       }
    }
    return nil;
}

Get products:

SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"xxxxx"]];

If it's going to be success, the following delegate will be called:

    - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    if (response.products == nil) {
        NSLog(@"No product belonging to the app!");
    }
    if ([response.invalidProductIdentifiers count] != 0) {
        NSLog(@"The following product indentifiers are invalid: %@",response.invalidProductIdentifiers);
    }
    for (SKProduct* prod in response.products) {
        NSLog(@"Proce: %@",prod.price);
    }

I hope this hepls for you.

Important:The code is untested, I just wrote it right now...

Good luck!
