The fact that NSConference was divided into Mac (first two days) and iPhone (third day) was not a best idea. Plenty of people have chosen the latter only because they were scared the former is too much “mac only”. It wasn’t. My advice to Mac Developer Network for next year: Don’t repeat this mistake. Let the people to choose session they have interest in. I have found all the sessions from both parts very valuable, although lots of topics were outside of my area of interest. I still dig through records discovering things I may need and the community driven notes (kudos to authors of great SubEthaEdit) created by attendees over network during the sessions are great. Not only helped me to recap all the details but also brought a whole new point of view on the topics:

The only regret I have is that I decided to drive from home everyday. It appears I missed a lot of fun not staying in the hotel overnight :)

Following is a list of detailed write-ups and great photos I know. If you want to contribute to this list, please do so in the comments. I will update accordingly.

Pick your fighter, pick your moves and send the challenge to a friend. He/She will pick a fighter and moves and the match will happen in turn based style. If you can predict opponent’s moves you can win.

Outline

This post is continuation of In-App Purchase: Quick Overview. This part focus on programming details. The outline of the steps to create and sell products is:

• create a test user in iTunes Connect Portal,
• define the application in the Developer Portal and enable in-app purchases,
• register new application in iTunes Connect Portal and a product (products) for it,
• develop the store within your application.

Create a test user in iTunes Connect Portal

Go to iTunes Connect Portal, (https://itunesconnect.apple.com), and click the option “Manage Users”, then choose “In App Purchase Test User” option and add a new User. Following screen shots will leave no doubts

Define the application in the Developer Portal and enable in-app purchases.

Go to Developer Program Portal (http://developer.apple.com) and select “App IDs” section. The next step will be create a new App ID. Select the top right button “New App ID”. In bundle identifier I recommend to use a string like this, “com.yourcompany.appname”.

Developer Program Portal -> App IDs -> New App ID.

3.- Create the new App on in iTunes Connect Portal, and Register a product for this App.

Now we create the app on iTunes Connect. Again go to iTunes Connect Portal and select “manage your applications”. On left top you can see the “add new application” button, click it, and follow the steps. On Pricing step, it’s very important that you select a payment application (Not free), cause the app purchases are only available on this kind of App.

iTunes Connect -> Manage your Applications -> Add new Application

Once the App has been created, you can see it on “Manage your applications”. To add In-app purchase, select the button “Manage in-app purchase”. In this page, you can create your app purchases using the top left button, “Create New”.

iTunes Connect -> Manage your Applications -> Manage in-app purchase.

* If your application is free, you can’t see this option

4.- Develop the store in your App.

This is the final step to use store kit. First of all it’s very important decide your application store model. Depending on how many items your store offers and how often you add new items, you may want to use one of two basic models: self-contained or downloadable content. In this tutorial we use a self-contained model.

In XCode, when you set up the project, make sure to link to StoreKit.framework.

Store Kit does not allow your application to patch itself or download additional code. For this the new feature must already exist in your application waiting to be unlocked

4.1.- Get the in-app purchase.

If you want to check the in-app purchase on your iphone app.

if (self = [super initWithFrame:frame]) {
[self requestProductData];
}
return self;
}
 
- (void)dealloc {
[super dealloc];
}
 
- (void) requestProductData
{
SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject: @"com.yourcompany.product "]];
request.delegate = self;
[request start];
}

SKProduct *product = [myProduct objectAtIndex:i];
NSLog(@”Name: %@ - Price: %f”,[product localizedTitle],[[product price] doubleValue]);
NSLog(@”Product identifier: %@”, [product productIdentifier]);
}
}
 
@end

4.2.- Buy a in-app purchase.

First of all you need register a transaction observer with the payment queue. For this you must create a instance class like this.

- (void) failedTransaction: (SKPaymentTransaction *)transaction;
- (void) restoreTransaction: (SKPaymentTransaction *)transaction;
- (void) completeTransaction: (SKPaymentTransaction *)transaction;

#import “CustomStoreObserver.h”
 
@implementation CustomStoreObserver
 
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
default:
break;
}
}
}
 
- (void) failedTransaction: (SKPaymentTransaction *)transaction
{
if (transaction.error.code != SKErrorPaymentCancelled)
{
// Optionally, display an error here.
}
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
 
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
//If you want to save the transaction
// [self recordTransaction: transaction];
 
//Provide the new content
// [self provideContent: transaction.originalTransaction.payment.productIdentifier];
 
//Finish the transaction
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
 
}
 
- (void) completeTransaction: (SKPaymentTransaction *)transaction
{
//If you want to save the transaction
// [self recordTransaction: transaction];
 
//Provide the new content
//[self provideContent: transaction.payment.productIdentifier];
 
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
 
}
 
@end

And in DummyView.m you can add a button with this Event Method to buy in-app purchase.

-(void) subscribe:(id) sender{
SKPayment *payment = [SKPayment paymentWithProductIdentifier:productIdentifier];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}

This is a simple tutorial to take a first look to Store Kit. I hope that it will be usefull for you.
