iOS内购

内购的前提:

有个人开发者账号;开通了银行业务;在开发者后台添加了内购产品;创建了相应的Bundle id 和证书;

第一,添加StoreKit.framework 框架;图1

图1

第二,配置相应的Bundile Indentfier 和证书;图2

图2

第三,#import <StoreKit/StoreKit.h>,添加协议SKPaymentTransactionObserver,SKProductsRequestDelegate

根据内购产品的id查询可以购买的产品:

NSSet * nsset = [NSSet setWithArray:arrProduct];

SKProductsRequest * request = [[SKProductsRequest alloc]initWithProductIdentifiers:nsset];

request.delegate = self;

[request start];

协议回调:

#pragma mark -- SKProductsRequestDelegate delegate

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{

NSArray * product = response.products;

if (product.count == 0) {//没有购买内购产品

[self.payDelegate onGetFail:non_Products];

}else{//返回内购产品

[self.payDelegate onGetSuccess:product];

}

}

-(void)request:(SKRequest *)request didFailWithError:(NSError *)error{

[self.payDelegate onGetFail:fail_Products];//获取有错

}

-(void)requestDidFinish:(SKRequest *)request{

//请求完成

}

第四,购买产品,product是 SKProduct 类型

-(void)getAppStorePay:(id)product{

[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

SKPayment * payment = [SKPayment paymentWithProduct:product];

[[SKPaymentQueue defaultQueue] addPayment:payment];

}

购买成功或者失败的回调:

#pragma mark -- SKPaymentTransactionObserver delegate//监听购买结果-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray*)transactions{

for(SKPaymentTransaction * tran in transactions){

//            NSLog(@"购买状态%ld",(long)tran.transactionState);

if (tran.transactionState == SKPaymentTransactionStatePurchased) {

//            NSLog(@"购买成功");

NSURL * receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];

// 从沙盒中获取到购买凭据

NSData * receiptData = [NSData dataWithContentsOfURL:receiptURL];

NSString * encodeStr = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];

[self.payDelegate onAppStorePaySuccess:encodeStr];

[[SKPaymentQueue defaultQueue] finishTransaction:tran];

}else if (tran.transactionState == SKPaymentTransactionStateRestored){

//            NSLog(@"重新购买");

[[SKPaymentQueue defaultQueue] finishTransaction:tran];

}else if (tran.transactionState == SKPaymentTransactionStateFailed){

//            NSLog(@"购买失败");

[self.payDelegate onAppStorePayFail];

[[SKPaymentQueue defaultQueue] finishTransaction:tran];

}

else if (tran.transactionState == SKPaymentTransactionStatePurchasing){

//            NSLog(@"正在购买");

}else{

//            NSLog(@"排队中");

}

}

}

//交易结束

- (void)completeTransaction:(SKPaymentTransaction *)transaction{

//    NSLog(@"交易完成");

[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}

- (void)dealloc{

[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];

}

获取到的购买凭证一般是放在后台进行验证:

#define ITMS_PROD_VERIFY_RECEIPT_URL        @"https://buy.itunes.apple.com/verifyReceipt"//验证上架的

#define ITMS_SANDBOX_VERIFY_RECEIPT_URL    @"https://sandbox.itunes.apple.com/verifyReceipt"//验证沙盒测试的

前端实例:

/*

验证购买凭证一般都是在服务端进行验证

*/

// 发送网络POST请求，对购买凭据进行验证

NSURL *url = [NSURL URLWithString:ITMS_SANDBOX_VERIFY_RECEIPT_URL];

// 国内访问苹果服务器比较慢，timeoutInterval需要长一点

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0f];

request.HTTPMethod = @"POST";

NSString *payload = [NSString stringWithFormat:@"{\"receipt-data\" : \"%@\"}", receiptData];

NSData *payloadData = [payload dataUsingEncoding:NSUTF8StringEncoding];

request.HTTPBody = payloadData;

// 提交验证请求，并获得官方的验证JSON结果

NSData *result = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

// 官方验证结果为空

if (result == nil) {

NSLog(@"验证失败");

}

NSDictionary * dict = [NSJSONSerialization JSONObjectWithData:result options:NSJSONReadingAllowFragments error:nil];

if (dict != nil) {

NSLog(@"验证成功");

}
