IOS IAP Tutorials

1. Create an app

First go to itunes Connect and press Manage Your applications

Next press Add New Applicationbutton to create the app

2. Create an IAP in your app

After creating the app, in the Manage Your Applications app icon, go to the app

You will see the screen click Manage in App purchases to access the IAP management screen

Notice the bundle ID on the left side, and in the Xcode project, the settings in Info.plist need to be the same as this bundle

(This bundle ID will be populated when the app is created)

This is the management screen for IAP, just press create Newbutton to create an IAP

In this image I've created three IAP.

The Product ID is the only product ID that can be used to request information about the IAP and the transaction

since the transaction is permanently valid, it is recommended thatthe Addtrans actionobserver this to be monitored when the app is started, rather than listening when the user wants to buy something .

The trading results are shown here

Apple to prepare sandbox test environment for a period of time, if you create an IAP to get information, but can not be successful trading, you have to wait a moment

In addition, if the simulator can buy, but the real machine purchase failed, do hard reset will be able to, always hold the home button and the power button to be able to do hard reset

Press and hold will appear the shutdown screen, do not ignore it, continue to wait until the white Apple appears, you can release and so on when it re-boot completed and then test
