專案裡面要接蘋果支付，結果我研究了一個小時的apple pay，結果經理說是蘋果內購，當時就感覺被耍了！好了，那就說說In-App Purchase這個吧，前面所有的準備工作經理做完了，我只是碼程式碼，結果購買的回撥都執行，就是介面啥反應都沒有，不知道是前期的工作沒做好，還是我的程式碼有問題？上程式碼：

第一步，匯入標頭檔案籤協議

// 在需要購買的介面裡面匯入，前提是你要將StoreKit框架新增到你的工程裡面
#import <StoreKit/StoreKit.h>
// 簽訂內購需要的兩個協議
@interface VIPViewController ()<SKPaymentTransactionObserver
 
,SKProductsRequestDelegate>
{

        NSInteger _index;// 購買的那件商品
}

第二步，選擇需要購買的商品，並請求商品資訊

// push到支付介面
- (void)pushApplePay:(NSInteger)index{

    _index = index;
    //判斷能不能購買
    // 裡面儲存的是本地化的商品資訊
    VipDataHandle *handle = [VipDataHandle sharedInstence];

    if([SKPaymentQueue canMakePayments]){
        [self
 
 requestProductData:handle.products[index]];
    }else{
        NSLog(@"不允許程式內付費");
    }
}

//請求商品
- (void)requestProductData:(NSString *)type{

    NSLog(@"-------------請求對應的產品資訊----------------");
    NSArray *product = [[NSArray alloc] initWithObjects:type,nil];

    NSSet *nsset = [NSSet setWithArray:product];
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:nsset];
    request.delegate
 
 = self;
    [request start];

}
//收到產品返回資訊
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{

    NSLog(@"--------------收到產品反饋訊息---------------------");
    NSArray *product = response.products;
    if([product count] == 0){
        NSLog(@"--------------沒有商品------------------");
        return;
    }
    NSLog(@"productID:%@", response.invalidProductIdentifiers);
    NSLog(@"產品付費數量:%ld",[product count]);

    SKProduct *p = nil;
    for (SKProduct *pro in product) {

        NSLog(@"description：%@", [pro description]);
        NSLog(@"localizedTitle：%@", [pro localizedTitle]);
        NSLog(@"localizedDescription：%@", [pro localizedDescription]);
        NSLog(@"price：%@", [pro price]);
        NSLog(@"productIdentifier：%@", [pro productIdentifier]);

        if([pro.productIdentifier isEqualToString:[VipDataHandle sharedInstence].products[_index]]){

            p = pro;
        }
    }

    SKPayment *payment = [SKPayment paymentWithProduct:p];

    NSLog(@"傳送購買請求");
    [[SKPaymentQueue defaultQueue] addPayment:payment];

}

//請求失敗
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error{

    NSLog(@"------------------錯誤-----------------:%@", error);
}

//資訊結束
- (void)requestDidFinish:(SKRequest *)request{

    NSLog(@"------------反饋資訊結束-----------------");
}

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

    NSLog(@"-----PurchasedTransaction----");
    NSArray *transactions =[[NSArray alloc] initWithObjects:transaction, nil];
    [self paymentQueue:[SKPaymentQueue defaultQueue] updatedTransactions:transactions];
}

第三步，監聽購買狀態

//監聽購買結果
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {

    for (SKPaymentTransaction *transaction in transactions){

        switch (transaction.transactionState){

            case SKPaymentTransactionStatePurchased://交易完成

                NSLog(@"transactionIdentifier = %@", transaction.transactionIdentifier);
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed://交易失敗

                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored://已經購買過該商品

                [self restoreTransaction:transaction];
                break;
            case SKPaymentTransactionStatePurchasing:      //商品新增進列表

                NSLog(@"商品新增進列表");
                break;
            default:
                break;
        }
    }
}
- (void)completeTransaction:(SKPaymentTransaction *)transaction {

    // Your application should implement these two methods.
    NSString * productIdentifier = transaction.payment.productIdentifier;

    if ([productIdentifier length] > 0) {
        // 向自己的伺服器驗證購買憑證

        NSLog(@"驗證購買");
    }
    // Remove the transaction from the payment queue.
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];

}
- (void)failedTransaction:(SKPaymentTransaction *)transaction {

    if(transaction.error.code != SKErrorPaymentCancelled) {
        NSLog(@"購買失敗");
    } else {
        NSLog(@"使用者取消交易");
    }
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction {
    // 對於已購商品，處理恢復購買的邏輯
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}

第四步，拿到蘋果返回來的票據去請求自己的伺服器，校驗是否正確

// 校驗支付真確性的方法
- (void)checkPay:(NSNotification *)note{

    [self appRequest:note.userInfo[@"appleData"]];
}

// 請求伺服器
- (void)appRequest:(NSString *)appleData{

    InAppPayStore *store = [[InAppPayStore alloc]init];
    store.delegate = self;
    store.uid = userId;
    store.appleData = appleData;
    [store request];
}
- (void)success{

    NSLog(@"支付成功");
}
- (void)failure:(NSString *)error{

    NSLog(@"支付失敗");
}

程式碼就是按照上面做的，請求返回的商品id也有，新增購買後，狀態就是新增購買，始終在介面上啥都不顯示，我也是醉了！當然了後面的票據校驗還沒做，前面的還沒通後面沒法做的，換了部手機就可以跳出支付介面，現在還在找原因

大神路過看看哈，請教
