1. 创建应用

首先进入iTunes Connect然后按下 Manage Your Applications

接下来按下Add New Applicationbutton创建应用

2. 在应用中创建IAP

创建应用之后，在Manage Your Applications中点应用的图示，进入应用

就会看到上图画面点击Manage In App Purchases就能够进入IAP的管理画面

在这边要注意左边的Bundle ID，在Xcode项目中，info.plist中的设定需与此Bundle同样

(此Bundle ID会在创建应用时填入)

此为IAP的管理画面，仅仅要按下Create Newbutton就可创建IAP

在本图中我已经创建好三个IAP

而当中要注意的是Product ID，仅仅要用Product ID就能够请求IAP的相关讯息及交易

Consumable

Non-Consumable

一次性付费，通经常使用在升级pro版或是移除广告等

Auto-Renewable Subscriptions

Free Subscription

Non-Renewing Subscription

3. 怎样创建沙盒測试用户

进入iTunes Connect，点击Manage Users

在这个画面中点下Test User

按下Add New User就能够了，Email Address就是登入沙盒測试的username

password的部份在Add New User时可自行创建

苹果准备沙盒測试环境需一段时间，若是创建IAP后能够取得资讯，却无法交易成功，要稍待一下

另外若是模拟器能够购买，但真机购买却失败的话，做Hard Reset就能够了，一直按住Home键跟电源键就能够做Hard Reset

按住后会出现关机画面，不要理会它，继续等，直到等到白苹果出现后，就能够放开等它重开机完成后再測试
