Ios iap tutorial

1. Create an application

First go to iTunes connect and then press manage your applications

Next, click Add new application to create an application.

2. Create an IAP in the Application

After the application is created, click the application icon in the Manage Your applications to enter the application

Click Manage in app purchases to go to The IAP management screen.

Note the bundle ID on the left. In the xcode project, the settings in info. plist must be the same as those in this bundle.

(This bundle ID will be filled in when the application is created)

This is the IAP management screen. You only need to press the create new button to create an IAP.

In this figure, three IAP instances have been created.

Pay attention to the product ID. You only need to use the product ID to request information and transactions of the IAP.

Consumable

Consumable, paid for each download

Non-consumable

One-time payment, usually used to upgrade the Pro version or remove advertisements.

Auto-renewable subscriptions

Auto Update Subscription

Free subdomains

Free Subscription

Non-renewing subgraphs

Non-automatic Update Subscription

3. How to Create a sandbox test user

Go to iTunes connect and Click Manage Users.

In this screen, click test user

Press add new user. Email address is the username used to log on to the sandbox for testing.

You can create the password when adding a new user.

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

Because transactions are permanently valid, we recommend that you listen to addtransactionobserver after the application is started, rather than when users want to buy things.

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

The transaction result is displayed here.

It may take some time for Apple to prepare a sandbox test environment. If you can obtain information after creating an IAP, but the transaction fails, you have to wait a moment.

In addition, if the simulator can be purchased, but the real machine purchase fails, you can do hard reset. Keep holding the Home Key and power key for hard reset.

After you press and hold it down, the screen will be shut down, ignore it, and wait until the white apple appears, you can open it and wait until it is restarted before testing.
