這邊文章對(duì)于注冊流程和注意事項(xiàng)說的非常的詳細(xì)了但是里面還是有很多的坑，我自己封了一個(gè)類用于針對(duì)自己項(xiàng)目的使用地址如下
個(gè)人demo里面有個(gè)
屏幕快照 2019-03-25 上午10.28.18.png
里面需要注意的幾個(gè)點(diǎn)：
#pragma mark - SKPaymentTransactionObserver // 監(jiān)聽購買結(jié)果
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions{
[CXLoadingHud dismissHud];
for (SKPaymentTransaction *tran in transactions) {
//NSLog(@"%ld====",(long)tran.transactionState);
switch (tran.transactionState) {
case SKPaymentTransactionStatePurchased: //交易完成
//訂閱特殊處理
if(tran.originalTransaction){
//如果是自動(dòng)續(xù)費(fèi)的訂單originalTransaction會(huì)有內(nèi)容
NSLog(@"自動(dòng)續(xù)費(fèi)的訂單,originalTransaction = %@",tran.originalTransaction.transactionIdentifier);
//tran.originalTransaction.transactionIdentifier

//[self verifyPurchaseWithPaymentTransaction:tran isTestServer:NO];
}else{
//普通購買，以及 第一次購買 自動(dòng)訂閱 第一次自動(dòng)訂閱一定會(huì)走這個(gè)方法，如果訂購成功后一定會(huì)走上面的判斷

如果tran.error 打印報(bào)錯(cuò)的話，沙盒測試的時(shí)候總是報(bào)無法連接itunes ，再確保你自己的前期準(zhǔn)備工作是ok的話，大概率都是蘋果自己的沙盒測試服務(wù)器自己gg了，經(jīng)歷過一次，坑爹的玩意，咋都找不出來，最后是蘋果自己的問題
NSLog(@"%@====",tran.error);
//SKErrorUnknown
[self failedTransaction:tran];
break;
default:
break;
}
}
}
// 交易結(jié)束

// Your application should implement these two methods.
// 票據(jù)的校驗(yàn)是保證內(nèi)購安全完成的非常關(guān)鍵的一步，一般有三種方式：
// 1、服務(wù)器驗(yàn)證，獲取票據(jù)信息后上傳至信任的服務(wù)器，由服務(wù)器完成與App Store的驗(yàn)證（提倡使用此方法，比較安全）我選擇的這種，但是會(huì)丟單，不過我暫時(shí)沒有處理，準(zhǔn)備用一個(gè)plist文件存儲(chǔ)下在app再次啟動(dòng)的時(shí)候請求下后臺(tái)，不過這個(gè)只是減少了丟單率而且，蘋果的支付做得很垃圾
// 2、本地票據(jù)校驗(yàn)
// 3、本地App Store請求驗(yàn)證
// NSString * productIdentifier = transaction.payment.productIdentifier;
// NSString * receipt = [transaction.transactionReceipt base64EncodedString];
// if ([productIdentifier length] > 0) {
//
// }
NSURL *recepitURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:recepitURL];
// 向自己的服務(wù)器驗(yàn)證購買憑證
//NSError *error;
//轉(zhuǎn)化為base64字符串
NSString *receiptString=[receipt base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
//網(wǎng)上轉(zhuǎn)換成base64后后臺(tái)一直解析不了需要如下處理除去receiptdata中的特殊字符
NSString *receipt1=[receiptString stringByReplacingOccurrencesOfString:@"\n" withString:@""];
NSString *receipt2=[receipt1 stringByReplacingOccurrencesOfString:@"\r" withString:@""];
NSString *receipt3=[receipt2 stringByReplacingOccurrencesOfString:@"+" withString:@"%2B"];
//最終將這個(gè)receipt3的發(fā)送給服務(wù)器去驗(yàn)證就沒問題啦！
//自動(dòng)訂閱（自動(dòng)續(xù)費(fèi)月卡）需要多加一個(gè)參數(shù)

#希望各位處理的時(shí)候能將 transaction_id 和 receipt都傳給后臺(tái)因?yàn)樘O果的receipt解析后里面有很多數(shù)據(jù)，transaction_id能夠幫助后臺(tái)迅速定位最新的訂單，因?yàn)闇y試的時(shí)候發(fā)現(xiàn)receipt里面有個(gè)數(shù)組，一般是最后一條數(shù)據(jù)是最新的，但是坑爹的蘋果總是變，有時(shí)候是數(shù)組的第一條，所以transaction_id至關(guān)重要，而且在自動(dòng)訂閱和消耗性兩類中，自動(dòng)訂閱的 transaction_id2和transaction_id在第一次請求的時(shí)候是一致的，后面的話，要區(qū)分只能transaction_id所以這個(gè)傳給后臺(tái)至關(guān)重要
