Question

I am working on in-app purchase. In my application we added the following code in appdelegate:

    #import "InappPurchaseAppDelegate.h"
    #import "MainController.h"
    #import "MKStoreManager.h"
    #import "MKStoreObserver.h"

    @implementation InappPurchaseAppDelegate

    @synthesize window;


    - (void)applicationDidFinishLaunching:(UIApplication *)application 
    { 
      [MKStoreManager sharedManager];


      navigationController = [[UINavigationController alloc] init];
      [window addSubview:navigationController.view];
      MainController *frontController =[[MainController alloc] init];
      [navigationController pushViewController:frontController animated:NO ];
      [frontController release];    // Override point for customization after      application launch
      [window makeKeyAndVisible];
    }

and added the following code in our controller:

    #import "MainController.h"
    #import "MKStoreManager.h"
    #import "MKStoreObserver.h"

    #import "InappPurchaseAppDelegate.h"


    @implementation MainController


    -(IBAction)InappPurchase:(id)sender
    {
      [[MKStoreManager sharedManager] buyFeatureA];

    }

I also added storekit framework but when the button is clicked nothing happens.

All you need to know is here: http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StoreKitGuide/Overview%20of%20the%20Store%20Kit%20API/OverviewoftheStoreKitAPI.html#//apple_ref/doc/uid/TP40008267-CH100-SW1

It shouldn’t take you more than half a day to implement it (maybe a bit more if the content resides on your servers and is not already in the bundle).
