二：代码部分
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"购买页面";
self.navigationItem.rightBarButtonItem = [self rightBarButtonWithName:NSLocalizedString(@"07-restore", nil) target:self action:@selector(restonreProduct)];
[self BuildUI];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
}
#pragma mark -- 购买按钮事件
-(void)buycommodity {
if ([SKPaymentQueue canMakePayments]) {
[self RequestProductData];
// NSLog(@"允许程序内付费购买");
}
else
{
// NSLog(@"不允许程序内付费购买");
[self MarkToViewString:NSLocalizedString(@"09-noOpenApplications", nil)];
}
}
-(void)RequestProductData
{
// NSLog(@"---------请求对应的产品信息------------");
NSArray *product = nil;
product=[[NSArray alloc] initWithObjects:ProductID,nil];
NSSet *nsset = [NSSet setWithArray:product];
SKProductsRequest *request=[[SKProductsRequest alloc] initWithProductIdentifiers: nsset];
request.delegate=self;
[request start];
}
//<SKProductsRequestDelegate> 请求协议
//收到的产品信息
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
// NSLog(@"-----------收到产品反馈信息--------------");
NSArray *myProduct = response.products;
if([myProduct count] == 0){
[SVProgressHUD dismiss];
// NSLog(@"--------------没有商品------------------");
return;
}
SKProduct *P = nil;
for(SKProduct *product in myProduct){
// NSLog(@"product info");
// NSLog(@"SKProduct 描述信息%@", [product description]);
// NSLog(@"产品标题 %@" , product.localizedTitle);
// NSLog(@"产品描述信息: %@" , product.localizedDescription);
// NSLog(@"价格: %@" , product.price);
// NSLog(@"Product id: %@" , product.productIdentifier);
if ([product.productIdentifier isEqualToString:ProductID]) {
P = product;
}
}
SKPayment *payment = nil;
payment = [SKPayment paymentWithProduct:P];
// NSLog(@"---------发送购买请求------------");
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
//监听购买结果
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transaction{
for(SKPaymentTransaction *tran in transaction){
switch (tran.transactionState) {
case SKPaymentTransactionStatePurchased:{
// NSLog(@"交易完成");
[self checkTransaction:tran];//去验证
}
break;
case SKPaymentTransactionStatePurchasing:
// NSLog(@"商品添加进列表");
break;
case SKPaymentTransactionStateRestored:{
// NSLog(@"已经购买过商品");
[self restoreTransaction:tran];
}
break;
case SKPaymentTransactionStateFailed:{
// NSLog(@"交易失败");
[[SKPaymentQueue defaultQueue] finishTransaction:tran];
[SVProgressHUD showErrorWithStatus:@"购买失败"];
}
break;
default:
break;
}
}
}
验证前检查看看是否有未完成订单
#pragma mark --检查本次支付信息，并与本地缓存信息对比，查看是否是未完成订单
- (void)checkTransaction:(SKPaymentTransaction *)transaction{
NSDictionary *saveDic = [[NSDictionary alloc]init];
saveDic = [DDKeychain keyChainLoad];
if (saveDic != nil) {
//取自支付队列未完成的商品ID去缓存中拿对应的信息.有就去验证
[self connetServerWithTransactionandPayInfo:transaction];
return;
}else{
//全新的支付
NSDictionary *newPayInfoDic = @{@"product_id":ProductID,
@"apple_orderid":transaction.transactionIdentifier};
/** 已Keychain将数据存起来 */
[self setOrderData:newPayInfoDic key:ProductID];
/** 服务器验证 */
[self connetServerWithTransactionandPayInfo:transaction];
}
}
#pragma mark -- server验证
- (void)connetServerWithTransactionandPayInfo:(SKPaymentTransaction *)transaction{
//从沙盒中获取交易凭证并且拼接成请求体数据
NSURL *receiptUrl=[[NSBundle mainBundle] appStoreReceiptURL];
NSData *receiptData=[NSData dataWithContentsOfURL:receiptUrl];
NSString *receiptString=[receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];//交易凭证转化为base64字符串
// /** 商品id 订单号 苹果的订单号 传给 后台（看你们后台要求）*/
/*
1.调用服务器接口验证成功一定要删除keyChain存储的数据
2. [[SKPaymentQueue defaultQueue]finishTransaction:transaction];
*/
}
非消耗商品苹果需要提供恢复购买按钮，在已经购买过商品调用恢复购买处理
#pragma mark -- 恢复购买
- (void)restonreProduct{
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
NSLog(@" 交易恢复处理");
[self checkTransaction:transaction];//去验证
}
内购基本完成，我项目审核已通过！
