Apple in-purchase notes

In-Apple purchases include 4 types: 1. Consumption, 2. Non-expendable; 3. Auto-renew subscription; 4. Non-renewal subscription.

First of all, there is a itunesconnect on the agreement, tax and Banking module has a bank card binding while complying with the various Apple Protocol Development Account, (how to apply for filling online Baidu a bunch)

Then remember to add the protocol before the Code

<SKPaymentTransactionObserver,SKProductsRequestDelegate,SKRequestDelegate>

The basic code required for purchase is as above;

1. Consumable type

The macro definition (or from the server to see the demand) gets the ID of the purchased product (the product ID requested on itunesconnect), and the code in the above

ProductID Replace with the ID of the purchased product

The return message is then sent to the server for processing

Then the server side and Apple make a purchase verification, confirm the purchase success, return to the client to purchase the product successfully

The client displays the appropriate purchase content.

2. Non-consumable type

With the consumption type, the only difference is to repeat the purchase, Apple will prompt you can not repeat the purchase. It has nothing to do with the client or the server.

3. Automatic subscription Renewal

Purchase process with consumption type, more than a recovery purchase, while the display must be reminded that the user is currently subscribed to automatic renewal of the text description, or the Apple audit may be rejected

When the process is resumed, the user clicks Restore purchase and executes

Restoreclick method

If the recovery process is normal (not normal, you need to check the contents of the product request, sandbox test account problems, etc. before the steps are wrong)

Restoretransaction method

After acquiring the user's purchase information, the client transmits to the server, the server side and Apple perform data validation, and the client displays the product content that the client should restore after verifying the error.

4. Non-renewal subscriptions

Purchase process and consumption type;

The recovery process needs to go to the page and click Restore to execute

Restoreclick method

At the same time execute the following code to obtain the user purchase record data, continue to obtain until the user or cancel recovery.

    Nsurlrequest *urlrequest = [nsurlrequest requestwithurl:[[nsbundle mainbundle] appstorereceipturl]];    Nserror *error = nil;    NSData *iapdata  = [nsurlconnection sendsynchronousrequest:urlrequest returningresponse:nil error:&error];        NSString *transactionreceiptstring = [Iapdata base64encodedstringwithoptions: Nsdatabase64encodingendlinewithlinefeed];

If the user has entered the AppleID, and the recovery operation is done;

At this point, the acquired user purchase record and the current recovery product ID are sent to the server, the server and Apple for purchase confirmation. If the product has already been purchased, the recovery success information is returned to the client. The client shows what needs to be restored to the presentation.
