iOS苹果内购代码(IAP)和问题记录(2023)

最近项目由于审核原因需要接入苹果内购，在阅读了大量文章和苹果文档后，比较顺利的完成了开发和提审（目前App Store已审核通过）。这里记录下整个开发流程中相关的代码开发和一些踩过的坑。
一、代码开发
1、引入苹果框架 StoreKit
#import <StoreKit/StoreKit.h>
2、校验设备是否支持内购支付
[SKPaymentQueue canMakePayments];
3、从苹果后台获取配置的产品是否存在
// productsId 为 App Store Connect 后台配置的产品ID
NSSet *identifiers = [NSSet setWithObjects:productsId, nil];
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:identifiers];
productsRequest.delegate = self;
[productsRequest start];
4、遵守 SKProductsRequestDelegate 协议，回调中获取可购买的产品信息
获取的信息包括：
-
response.products：可购买的产品列表。 -
response.invalidProductIdentifiers：无效的产品信息。
这个地方有个巨大深坑：如果前面没有签署付费协议、银行账户和报税表没有完成审核、配置产品的信息状态不是“准备提交”状态，只要有一条不满足，就获取不到产品信息。即使以上信息都达到要求，也有可能获取不到产品信息！！！我就遇见了这种情况，最后在阅读了大量文章后，有篇文章建议如果确认后台已经配置好产品信息，可以手动将产品信息添加到购买队列（参考下面第5步中添加产品到购买队列），执行一次购买之后，当前回调方法就可以正常获取产品信息了。
#pragma mark - SKProductsRequestDelegate
/// 获取商品信息代理回调
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
NSArray *products = [NSArray arrayWithArray:response.products];
NSArray *invalidProductIdentifiers = [NSArray arrayWithArray:response.invalidProductIdentifiers];
/// 获取可购买产品id
if (products.count > 0) {
for (SKProduct *product in products) {
NSLog(@"可购买产品id: %@", product.productIdentifier);
[self addPayment:product];
}
} else {
/// 获取不到产品则手动添加产品到购买队列（确保苹果后台已配置相应产品id）
SKMutablePayment *payment = [[SKMutablePayment alloc] init];
// payment.applicationUsername = @"_orderId12"; //透传参数。可以传你自己的订单号，后续可能用得到
payment.productIdentifier = self.productsId;
payment.quantity = 1;
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
/// 无效的产品id
[invalidProductIdentifiers enumerateObjectsUsingBlock:^(NSString *invalid, NSUInteger idx, BOOL *stop) {
NSLog(@"无效的产品id: %@", invalid);
}];
}
遵守SKRequestDelegate 协议，可以获取请求完成和失败的方法：
#pragma mark - SKRequestDelegate
- (void)requestDidFinish:(SKRequest *)request {
NSLog(@"%s",__func__);
}
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error {
NSLog(@"%s",__func__);
NSLog(@"error userInfos: ",error.userInfo);
NSLog(@"error _domain: ",error.domain);
}
5、获取到信息之后，添加产品到购买队列
/// 添加到购买队列-调起支付
- (void)addPayment:(SKProduct *)product {
SKMutablePayment *payment = [SKMutablePayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
如果未获取产品信息，则手动创建产品并添加到购买队列
/// 获取不到产品则手动添加产品到购买队列（确保苹果后台已配置相应产品id）
SKMutablePayment *payment = [[SKMutablePayment alloc] init];
/// 透传参数。可以传你自己的订单号，后续可能用得到
// payment.applicationUsername = @"_orderId12";
/// productsId 为 App Store Connect 后台配置的产品ID
payment.productIdentifier = productsId;
payment.quantity = 1;
[[SKPaymentQueue defaultQueue] addPayment:payment];
将产品添加到购买队列后，则会提示在弹窗中输入沙盒账号，输入沙盒账号之后，会将账号保存到设置- App Store -沙盒账户。此后会调起苹果支付的弹窗，点击购买或者取消弹窗，即可在流程6回调方法中获取到相应的支付结果。
6、添加观察者 SKPaymentTransactionObserver，监听后续的支付结果
/// 添加观察者
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
/// 移除观察者
- (void)dealloc {
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
NSLog(@"%s",__func__);
}
代理方法监听后续的支付结果：
#pragma mark - SKPaymentTransactionObserver
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchased: { /// 交易成功
NSLog(@"【支付结果】======= 交易成功");
[self transactionSucceed:transaction];
}
break;
case SKPaymentTransactionStateFailed: { /// 交易失败
NSLog(@"【支付结果】======= 交易失败");
[self transactionFailed:transaction];
}
break;
case SKPaymentTransactionStatePurchasing: { /// 商品添加进列表
NSLog(@"【支付结果】======= 商品添加进列表");
}
break;
case SKPaymentTransactionStateRestored: { /// 已购买过该商品
NSLog(@"【支付结果】======= 已购买过该商品");
[self transactionFailed:transaction];
}
break;
case SKPaymentTransactionStateDeferred: { /// 交易延迟
NSLog(@"【支付结果】======= 交易延迟");
[self transactionFailed:transaction];
}
break;
default:
{
[self transactionFailed:transaction];
}
break;
}
}
}
7、交易成功之后，将获取的交易凭证发送给后端，让后端去苹果服务器进行校验
/// 交易结束-成功
- (void)transactionSucceed:(SKPaymentTransaction *)transaction {
/// 这里的URL测试环境下为沙盒url，上线版本中应为苹果后台的URL
NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receiptData = [NSData dataWithContentsOfURL:receiptUrl];
/// 转化为base64字符串
NSString *receiptString = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
NSLog(@"交易成功 receiptUrl = %@",receiptUrl);
NSLog(@"交易成功 receiptData = %@",receiptData);
NSLog(@"交易成功 receiptString = %@",receiptString);
/// 客户端请求苹果接口进行票据校验（该操作由服务器来验证）
// NSString *SandboxUrl = @"https://sandbox.itunes.apple.com/verifyReceipt";
// NSString *url = @"https://buy.itunes.apple.com/verifyReceipt";
// [self localReceiptVerifyingWithUrl:SandboxUrl AndReceipt:receiptString AndTransaction:transaction];
// 向自己的服务器验证购买凭证（此处应该考虑将凭证本地保存,对服务器有失败重发机制）
/**
服务器要做的事情:
接收ios端发过来的购买凭证。
判断凭证是否已经存在或验证过，然后存储该凭证。
将该凭证发送到苹果的服务器验证，并将验证结果返回给客户端。
如果需要，修改用户相应的会员权限
*/
// 监听购买结果，当失败和成功时代码中要调用如下代码:
// 该方法通知苹果支付队列该交易已完成，不然就会已发起相同 ID 的商品购买就会有此项目将免费恢复的提示。
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
同时处理交易失败：
/// 交易失败
- (void)transactionFailed:(SKPaymentTransaction *)transaction {
if (transaction.error.code == SKErrorPaymentCancelled){
NSLog(@"您取消了内购操作.");
} else {
NSLog(@"内购失败，原因：%@",[transaction.error localizedDescription]);
}
NSLog(@"transactionFailed with tid: %@ and code:%li and msg:%@", transaction.transactionIdentifier,(long)transaction.error.code,transaction.error.localizedDescription);
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
备注：
1、不管交易成功还是失败，处理完逻辑一定要调用 [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; 告诉苹果已完成当前操作，不然之后再购买就会失败！
2、共享密钥 password 获取路径：App Store Connect 后台-用户和访问-共享密钥。获取共享密钥
3、这里获取到的交易凭证比较长，如果要是发给后端先调试逻辑的话一定要复制完整。大约有5000个字节（搞不懂为啥要这么长）。参考如下：

}
8、这里提供一个方法，客户端可以手动去苹果服务器进行票据校验（只是测试而已，建议交给后端去做校验）
/// 请求苹果接口进行票据校验
- (void)localReceiptVerifyingWithUrl:(NSString *)requestUrl AndReceipt:(NSString *)receiptStr AndTransaction:(SKPaymentTransaction *)transaction
{
NSDictionary *requestContents = @{@"receipt-data": receiptStr,};
NSError *error;
// 转换为 JSON 格式
NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents
options:0
error:&error];
NSString *verifyUrlString = requestUrl;
NSMutableURLRequest *storeRequest = [NSMutableURLRequest requestWithURL:[[NSURL alloc] initWithString:verifyUrlString] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0f];
[storeRequest setHTTPMethod:@"POST"];
[storeRequest setHTTPBody:requestData];
// 在后台对列中提交验证请求，并获得官方的验证JSON结果
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:storeRequest completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (error) {
NSLog(@"链接失败");
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
} else {
NSError *error;
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (!jsonResponse) {
NSLog(@"验证失败");
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
NSLog(@"验证成功");
//TODO:取这个json的数据去判断，道具是否下发
}
}];
[task resume];
}
以上就是相关代码。
二、问题记录
1、获取不到产品信息
- 协议、税务和银行业务信息是否录入正确并提交审核完成。状态为图2中的“有效”。
- App Store Connect 后台配置产品信息是否正确，产品状态是否为“准备提交”。
- Xcode中是否添加“In-App Purchase”配置项。
- 当前开发证书的bundle ID和 App Store Connect中配置了产品的 App的bundle ID是否一致。（一定要一致）
- 是否调试设备中的App 存在缓存，可卸载重装。
- 确定是真机测试且手机没有越狱。
- 以上都没问题，还获取不到，可在确保后台配置产品的情况下，先手动将产品添加到购买队列。（参考流程五中第5步）
2、代理方法中获取不到支付结果
问题：能够获取产品信息，并将产品添加购买队列中，但是在代理方法 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions 中监听不到支付结果？
解决：检查当前类在调用完成后是否直接被dealloc了，要确保将产品添加到购买队列后当前类仍然存活，不会提前被销毁。不然就接收不到代理回调，也就监听不到支付结果。可以使用单例来保证类的存活。
3、苹果应用内支付,您已购买此App内购买项目。此项目将免费恢复
问题：使用沙箱账号（TestFlight邀请的账号没问题）重复充值同一个消耗型项目时，普通包没问题，但TestFlight包却提示"苹果应用内支付,您已购买此App内购买项目。此项目将免费恢复"，表示不能重复充值？
原因：苹果的服务器对大陆访问很慢(特别在沙盒测试环境更加不好)，导致用户在购买成功后，收不到苹果的IAP支付成功通知，交易就会一直卡在那里，没有关闭掉，后面无论怎样支付都是提示 “您已购买此App内购买项目。此项目将免费恢复”。
结果：不用解决，直接审核也能通过。目前猜测：1、审核人员用的是他们自己的沙箱账号；2、服务器在美国，审核人员也在美国。可能访问比较快。：）
如果开发过程中遇见了其他无法解决的问题，建议可以大量阅读网上有关内购的文章，以及苹果官方的内购文档。有可能在读到某句话时，你的问题就瞬间迎刃而解了。
