第一部分：在Apple后臺(tái)添加一個(gè)內(nèi)購(gòu)產(chǎn)品

1蜡饵、登錄appStoreConnect,如下圖所示，添加一個(gè)商品

增加內(nèi)購(gòu).png

IAP類(lèi)型類(lèi)型主要有4種：

1、Consumable products 適用于可多次購(gòu)買(mǎi)的消耗型項(xiàng)目，如游戲道具胸蛛、虛擬幣等。

2樱报、Non-consumable products 適用于一次購(gòu)買(mǎi)永久有效的項(xiàng)目葬项，如電子書(shū)、游戲關(guān)卡等迹蛤。該類(lèi)型項(xiàng)目支持跨設(shè)備同步和本地restore民珍，比如說(shuō)，用戶(hù)在某個(gè)App中購(gòu)買(mǎi)了一本書(shū)盗飒，可在所有相同Apple ID設(shè)備的App中免費(fèi)獲取這本書(shū)嚷量。

3、Auto-renewable subscriptions 適用于自動(dòng)續(xù)費(fèi)的訂閱項(xiàng)目逆趣，如Apple Music的按月訂閱蝶溶，用戶(hù)購(gòu)買(mǎi)后會(huì)每月自動(dòng)續(xù)費(fèi)，直到用戶(hù)手動(dòng)取消或者開(kāi)發(fā)者下架IAP項(xiàng)目宣渗。

4抖所、Non-renewable subscriptions 適用于固定有效期的非自動(dòng)續(xù)費(fèi)項(xiàng)目，如云音樂(lè)的會(huì)員和一些視頻App的會(huì)員痕囱。

由于我們是充值虛擬幣學(xué)點(diǎn)田轧，所以選擇了Consumable類(lèi)型。

2咐蝇、填寫(xiě)商品名稱(chēng)涯鲁、Product ID（Product ID一旦創(chuàng)建不可修改），選擇價(jià)格有序，然后拉到最下面添加商品購(gòu)買(mǎi)時(shí)的截圖抹腿，最后保存

創(chuàng)建一個(gè)學(xué)點(diǎn).jpeg

點(diǎn)擊④，會(huì)進(jìn)入價(jià)格列表旭寿，對(duì)照下圖中的價(jià)格警绩，選擇商品想要賣(mài)的價(jià)格在③中進(jìn)行選擇

價(jià)格參考.jpg

3、記住要添加截圖盅称，不然狀態(tài)會(huì)變成Miss Metadata肩祥，添加截圖數(shù)據(jù)沒(méi)有問(wèn)題后會(huì)變成Ready to Submit狀態(tài)

MissMetaData.jpeg

4、在App提交審核時(shí)缩膝，把App當(dāng)前版本用到的內(nèi)購(gòu)商品添加到App中混狠，不添加的話，蘋(píng)果審核會(huì)被拒絕疾层，報(bào)你有一個(gè)或多個(gè)內(nèi)購(gòu)商品沒(méi)有提交審核的Issue

添加內(nèi)購(gòu)商品.png

第二部分：蘋(píng)果支付流程

支付流程簡(jiǎn)單來(lái)講就是在App中點(diǎn)擊購(gòu)買(mǎi)商品按鈕的時(shí)候,把在Apple后臺(tái)設(shè)置的Product ID通過(guò)SKProductsRequest傳給Apple后臺(tái)将饺，Apple后臺(tái)會(huì)把商品對(duì)象SKProduct回調(diào)給App，然后再把SKProduct加到支付隊(duì)列中，這個(gè)時(shí)候就會(huì)有彈框顯示支付金額讓你輸密碼了予弧，支付成功后蘋(píng)果會(huì)把交易憑證返回刮吧，拿著憑證去公司服務(wù)器驗(yàn)證，驗(yàn)證為有效憑證發(fā)學(xué)點(diǎn)掖蛤，交易完成

1.點(diǎn)擊購(gòu)買(mǎi)商品按鈕時(shí)傳入在Apple后臺(tái)的In-App Purchases中設(shè)置的相應(yīng)的Product ID

2杀捻、傳入Product ID參數(shù)，通過(guò)SKProductsRequest發(fā)起請(qǐng)求蚓庭，監(jiān)聽(tīng)回調(diào)結(jié)果

-(void)starBuyToAppStoreWithGoodsId:(NSString *)goodsID cannotPayment:(void(^)(void))cannotPayment{
    //判斷app是否允許apple支付
    if (![SKPaymentQueue canMakePayments]) {
        if (cannotPayment) {
            cannotPayment();
        }
        return;
    }
    //1.點(diǎn)擊購(gòu)買(mǎi)商品時(shí)傳入在Apple后臺(tái)的In-App Purchases中設(shè)置的相應(yīng)的Product ID
    //goodsID 就是在蘋(píng)果后臺(tái)設(shè)置的商品ID
    self.goodsId = goodsID; //比如Product ID可以是 com.example.example_LevelA
    NSArray *product = [[NSArray alloc] initWithObjects:goodsID,nil];
    NSSet *nsset = [NSSet setWithArray:product];
    
    //2致讥、傳入Product ID參數(shù)，通過(guò)SKProductsRequest發(fā)起請(qǐng)求器赞，監(jiān)聽(tīng)回調(diào)結(jié)果
    SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:nsset];
    request.delegate = self;
    [request start];
}

3拄踪、在需要監(jiān)聽(tīng)商品請(qǐng)求回調(diào)的地方,實(shí)現(xiàn)SKProductsRequestDelegate,確保Apple后臺(tái)返回的Product ID與步驟2中請(qǐng)求的一樣

4、把SKProduct加到支付隊(duì)列之前拳魁，創(chuàng)建一個(gè)訂單持久化到本地惶桐，用戶(hù)可以查看訂單狀態(tài)，在支付流程中會(huì)遇到各種情況導(dǎo)致支付失敗潘懊，至少可以列舉5種可能的狀態(tài)：0=待充值姚糊，1=充值完成，2=充值中授舟，3=充值取消救恨，4=充值失敗，可以根據(jù)各種狀態(tài)去更新訂單狀態(tài)

5释树、把SKProduct加入到支付隊(duì)列中肠槽，并給SKMutablePayment對(duì)象添加唯一標(biāo)識(shí)用于交易結(jié)束后獲取相應(yīng)的訂單改變訂單狀態(tài)，當(dāng)被成功添加到支付隊(duì)列后這個(gè)時(shí)候就會(huì)有彈框了

#pragma mark -SKProductsRequestDelegate
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    NSArray *products = response.products;
    
    if([products count] == 0){
        if (self.delegate && [self.delegate respondsToSelector:@selector(appStorePayFailed)]) {
            [self.delegate appStorePayFailed];
        }
        return;
    }
    
    //3奢啥、在需要監(jiān)聽(tīng)商品請(qǐng)求回調(diào)的地方,實(shí)現(xiàn)SKProductsRequestDelegate,確保Apple后臺(tái)返回的Product ID與步驟2中請(qǐng)求的一樣
    SKProduct *requestProduct = nil;
    for (SKProduct *product in products) {
        if([product.productIdentifier isEqualToString:self.goodsId]){
            requestProduct = product;
            break;
        }
    }
    
    if (!requestProduct) {
        return;
    }
    
//4秸仙、把SKProduct加到支付隊(duì)列之前，創(chuàng)建一個(gè)訂單持久化到本地桩盲，用戶(hù)可以查看訂單狀態(tài)寂纪，在支付流程中會(huì)遇到各種情況導(dǎo)致支付失敗，至少可以列舉5種可能的狀態(tài)：0=待充值赌结，1=充值完成捞蛋，2=充值中，3=充值取消柬姚，4=充值失敗拟杉，可以根據(jù)各種狀態(tài)去更新訂單狀態(tài)
    NSString *startTime = [NSString stringWithFormat:@"%.0f", [NSDate date].timeIntervalSince1970];
    NSString *applicationUsername = [NSString stringWithFormat:@"%@/%@/%@",[ZGAppInfoUtil appID], startTime, requestProduct.price];
    NSDictionary *dict = @{
        @"price" : requestProduct.price,
        @"startTime" : startTime,
        @"status" : @(InAppPurchaseStatusPrepare),
        @"receiptData" : @"",
        @"transactionID" : @"",
        @"applicationUserName" : applicationUsername
    };
    [self.chargeManager makeLearnPointOrderWithInfo:dict];
    
    
    //5、把SKProduct加入到支付隊(duì)列中量承，并給SKMutablePayment對(duì)象添加唯一標(biāo)識(shí)用于交易結(jié)束后獲取相應(yīng)的訂單改變訂單狀態(tài)搬设，當(dāng)被成功添加到支付隊(duì)列后這個(gè)時(shí)候就會(huì)有彈框了
    SKMutablePayment *payment = [SKMutablePayment paymentWithProduct:requestProduct];
    payment.applicationUsername = applicationUsername;
    [[SKPaymentQueue defaultQueue] addPayment:payment];//將票據(jù)加入到交易隊(duì)列
}

6啼染、監(jiān)聽(tīng)購(gòu)買(mǎi)結(jié)果 - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions，根據(jù)不同的交易狀態(tài)去處理相應(yīng)的邏輯

    for (SKPaymentTransaction *transaction in transactions) {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchasing:
                NSLog(@"交易已經(jīng)添加到服務(wù)隊(duì)列中");

    }
}

7阀蒂、當(dāng)交易狀態(tài)為SKPaymentTransactionStatePurchased该窗，意味著支付完成了，從沙盒中獲取交易憑證

8蚤霞、拿到交易憑證后酗失，在去后臺(tái)服務(wù)器后臺(tái)驗(yàn)證之前，需要把訂單狀態(tài)改為充值中昧绣，在持久化的訂單列表中對(duì)狀態(tài)為充值中的訂單可以發(fā)起補(bǔ)充值請(qǐng)求

第三部分：訂單狀態(tài)記錄

在發(fā)起支付的過(guò)程中會(huì)遇到各種各樣的問(wèn)題氓涣，比如用戶(hù)中途取消、用戶(hù)支付完成后拿著交易憑證去公司服務(wù)器驗(yàn)證的時(shí)候網(wǎng)絡(luò)不好或者公司服務(wù)器掛了陋气，為了防止掉單也讓用戶(hù)看到自己訂單的支付記錄劳吠，有必要在本地使用Plist持久化一個(gè)訂單列表

1、在Document目錄下創(chuàng)建一個(gè)Plist文件

- (NSString *)filePath {
    if (!_filePath) {
        NSString *document = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject;
        NSString *path = [document stringByAppendingPathComponent:@"PointCoinOrder.plist"];
        _filePath = path;
    }
    return _filePath;
}

2巩趁、創(chuàng)建訂單痒玩，更新訂單 （因?yàn)橐粭l訂單信息在支付流程的不同階段淳附，最終的狀態(tài)會(huì)發(fā)生改變(創(chuàng)建、取消蠢古、失敗奴曙、完成等)，需要要把老的訂單刪除草讶，更新訂單狀態(tài)信息之后的訂單追加進(jìn)去）

- (dispatch_queue_t)queue {
    if (!_queue) {
        _queue = dispatch_queue_create("com.example.xxxxx", DISPATCH_QUEUE_SERIAL);
    }
    return _queue;
}

- (void)makeLearnPointOrderWithInfo:(NSDictionary *)dict {
    dispatch_async(self.queue, ^{
        NSMutableArray *resultArray = [NSMutableArray arrayWithArray:[NSArray arrayWithContentsOfFile:self.filePath]];
        //因?yàn)橐粭l訂單信息在支付流程的不同階段洽糟，最終的狀態(tài)會(huì)發(fā)生改變(創(chuàng)建、取消堕战、失敗坤溃、完成等)，需要要把老的訂單刪除嘱丢，更新?tīng)顟B(tài)信息之后的訂單追加進(jìn)去
        for (NSDictionary *subDict in resultArray) {
            if ([[subDict objectForKey:@"applicationUserName"] isEqualToString:[dict objectForKey:@"applicationUserName"]]) {
                [resultArray removeObject:subDict];
                break;
            }
        }
        if (dict) {
            [resultArray addObject:dict];
        }
        [resultArray writeToFile:self.filePath atomically:YES];
    });
}

//根據(jù)訂單的ID獲取訂單
- (NSDictionary *)getLearnPointOrderWithApplicationUsername:(NSString *)applicationUsername {
    NSMutableArray *resultArray = [NSMutableArray arrayWithArray:[NSArray arrayWithContentsOfFile:self.filePath]];
    NSMutableDictionary *resultDict;
    for (NSDictionary *subDict in resultArray) {
        if ([[subDict objectForKey:@"applicationUserName"] isEqualToString:applicationUsername]) {
            resultDict = [NSMutableDictionary dictionaryWithDictionary:subDict];
            //移除舊的字典
            [resultArray removeObject:subDict];
            break;
        }
    }
    return resultDict;

}

3薪介、去公司服務(wù)器驗(yàn)證訂單

+ (void)verifyToServerWithReceipt:(NSDictionary *)receiptInfo success:(void(^)(NSDictionary *result))success fail:(void(^)(NSError *error))fail {
    
}
