学如逆水行舟，不进则退。
今天和大家来聊聊iOS内购即In-App Purchase，内购分为消耗型、非消耗型、自动订阅、非自动订阅型。
内购流程
配置App内购买项目（可以参考苹果官方文档）
- 在iTC后台接收付费协议
- 创建App内购买项目
- 创建沙盒账号，用于测试
代码实现
- 从苹果请求商品详情
- (void)requestIAPProducts:(NSSet<NSString *> *)productIds
{
SKProductsRequest *productReq = [[SKProductsRequest alloc] initWithProductIdentifiers:productIds];
productReq.delegate = self;// SKProductsRequestDelegate
[productReq start];
}
- 实现SKProductsRequestDelegate代理，如果获取到商品的话就执行购买行为
#pragma mark SKProductsRequestDelegate
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
[response.products enumerateObjectsUsingBlock:^(SKProduct * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
}];
[response.invalidProductIdentifiers enumerateObjectsUsingBlock:^(NSString * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
}];
// 开始购买
if (response.products.count > 0) {
SKProduct *product = response.products.firstObject;
SKMutablePayment *payment = [[SKMutablePayment alloc] init];
payment.applicationUsername = @"uid";
payment.productIdentifier = product.productIdentifier;
payment.quantity = 1;
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
}
- (void)requestDidFinish:(SKRequest *)request
{
}
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error
{
}
- 监听商品支付结果：SKPaymentTransactionObserver
#pragma mark SKPaymentTransactionObserver
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions
{
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
// 1、购买成功
// 2、购买成功，但是你没有finish掉，没有消耗
case SKPaymentTransactionStatePurchased: {
//自动订阅订单抛出，只有自动订阅订单originalTransaction才会有值
if (transaction.originalTransaction) {
} else {
}
// 对于成功的订单需要先到后台校验 成功后才可以消单
// [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
case SKPaymentTransactionStateFailed: {
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
case SKPaymentTransactionStateRestored: {
// [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
case SKPaymentTransactionStatePurchasing: {
break;
}
case SKPaymentTransactionStateDeferred: {
break;
}
default: {
break;
}
}
}
}
- 后台校验订单

正式订单校验：https://buy.itunes.apple.com/verifyReceipt

发布上线
代码实现开发完成后，可以跟着版本一起发布，也可以单独审核内购，看具体需求
内购常见错误
- 获取不到商品信息：检查itc商品审核以及下线情况，检查设备知否支持内购
- 无法连接: 网络问题，切记沙盒环境下不可开vpn或者网络代理
- 21000 App Store无法读取你提供的JSON数据
- 21002 收据数据不符合格式
- 21003 收据无法被验证
- 21004 你提供的共享密钥和账户的共享密钥不一致
- 21005 收据服务器当前不可用
- 21006 收据是有效的，但订阅服务已经过期。当收到这个信息时，解码后的收据信息也包含在返回内容中
- 21007 收据信息是测试用（sandbox），但却被发送到产品环境中验证
- 21008 收据信息是产品环境中使用，但却被发送到测试环境中验证
