內(nèi)購流程：
內(nèi)購流程圖.png
用戶先拿到購買產(chǎn)品的單子举塔，
拿著單子去蘋果那里交錢输玷，交完錢讓蘋果在單子上蓋個(gè)章
3.拿著蓋了章的單子傳給自己的服務(wù)器來驗(yàn)證是否真的支付成功,服務(wù)器是跟蘋果驗(yàn)證（我們客戶端也是可以跟蘋果驗(yàn)證的车柠，只是這樣安全性不高）
4.根據(jù)服務(wù)器返回的信息做具體的處理
先上代碼干貨
- 設(shè)置這個(gè)監(jiān)聽對(duì)象立砸，會(huì)在該界面時(shí)時(shí)監(jiān)測(cè)支付的狀態(tài)變化

- 下面這個(gè)方法就功能很多了
- 如果內(nèi)購流程中的蘋果支付完成妈拌，但是由于某些原因，沒有結(jié)束該交易，蘋果是會(huì)在頁面出現(xiàn)的時(shí)候尘分，回調(diào)這個(gè)交易的票據(jù)數(shù)據(jù)的猜惋，所以要有一個(gè)變量，標(biāo)志SKPaymentTransactionStatePurchased是充值的時(shí)候培愁，還是頁面啟動(dòng)的時(shí)候回調(diào)的_isBuying

我們可以看到谍咆，使用數(shù)據(jù)庫了原因是
- 在蘋果返回票據(jù)，支付成功的時(shí)候私股，之后的流程摹察，我們走的是自己的服務(wù)器去驗(yàn)證，這樣的話倡鲸，中間流程一旦中斷供嚎，這個(gè)交易就可能沒有結(jié)束，然后呢旦签，蘋果的監(jiān)聽查坪，就會(huì)給回調(diào)回來之前支付成功但是并未結(jié)束交易的票據(jù)數(shù)組。
- 但是并不能直接調(diào)用充值接口宁炫，因?yàn)槲抑Ц冻晒Τナ铮ⅠR殺掉進(jìn)程，重新啟動(dòng)羔巢，換個(gè)賬號(hào)望忆，進(jìn)入充值界面的話，就會(huì)充值給另一個(gè)用戶竿秆，所以需要判斷這個(gè)交易的用戶屬性启摄，采用了數(shù)據(jù)庫保存，發(fā)起的訂單幽钢，當(dāng)然成功的單子就刪除了【當(dāng)然也有個(gè)問題歉备，及時(shí)極限操作，蘋果的支付票據(jù)還沒回來匪燕，我就殺掉app蕾羊，自然也就不能本地保存了，雖然沒人這么做帽驯，所以存了一下龟再，發(fā)起交易的人的uid，方便處理漏掉的單子的時(shí)候尼变，不要給另外的人存了錢利凑，自然最后剩余的情況就讓找客服吧，無解了】
- 這是條分割線
// 蘋果內(nèi)購支付成功
- (void)buyAppleStoreProductSucceedWithPaymentTransactionp:(SKPaymentTransaction *)paymentTransactionp {
NSString * productIdentifier = paymentTransactionp.payment.productIdentifier;
DebugLog(@"productIdentifier Product id：%@", productIdentifier);

//系統(tǒng)IOS7.0以上獲取支付驗(yàn)證憑證的方式應(yīng)該改變，切驗(yàn)證返回的數(shù)據(jù)結(jié)構(gòu)也不一樣了哀澈。
NSString *version = [UIDevice currentDevice].systemVersion;
if([version intValue] >= 7.0){
// 驗(yàn)證憑據(jù)牌借，獲取到蘋果返回的交易憑據(jù)
// appStoreReceiptURL iOS7.0增加的，購買交易完成后日丹，會(huì)將憑據(jù)存放在該地址
NSURLRequest * appstoreRequest = [NSURLRequest requestWithURL:[[NSBundle mainBundle]appStoreReceiptURL]];
NSError *error = nil;
NSData * receiptData = [NSURLConnection sendSynchronousRequest:appstoreRequest returningResponse:nil error:&error];
transactionReceiptString = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
}else{
NSData * receiptData = paymentTransactionp.transactionReceipt;
// transactionReceiptString = [receiptData base64EncodedString];
transactionReceiptString = [receiptData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
}
// 去驗(yàn)證是否真正的支付成功了
[self checkAppStorePayResultWithBase64String:transactionReceiptString WithPaymentTransactionp:paymentTransactionp];
}
下面方法走哺，接口調(diào)用成功的話，因?yàn)闋顟B(tài)值是0的話哲虾，原因是已經(jīng)充值成功，或者票據(jù)不對(duì)择示，這兩種情況也必須直接結(jié)束交易束凑，所以只要接口調(diào)用成功，一樣結(jié)束交易
接口調(diào)用失敗的話栅盲，再次調(diào)用汪诉，直到成功
