2018iOS內(nèi)購詳細(xì)教程&iOS內(nèi)購我踩過的坑(出現(xiàn)的問題以及優(yōu)化方案&一些細(xì)節(jié)處理)

首先,在我上一次發(fā)的這篇文章里http://www.reibang.com/p/d2b3f297ba9e 存在幾個(gè)容易出現(xiàn)問題的點(diǎn)吃度，在實(shí)際的運(yùn)營中確實(shí)也出現(xiàn)過匹涮，所以針對出現(xiàn)的問題也做了一下優(yōu)化，希望對大家有幫助。

問題一

在前一篇內(nèi)購的代碼中坞生，在實(shí)際運(yùn)營中仔役，出現(xiàn)過獲取不到平臺訂單號，也就是applicationUsername為nil的情況恨胚，這種情況是因?yàn)樘O果返回參數(shù)為nil導(dǎo)致的漏單骂因，所以說這個(gè)參數(shù)并不是完全的可靠。所以赃泡，有必要在這個(gè)參數(shù)返回為nil 的時(shí)候做一下處理寒波。首先有兩種方案：

一、可以在本地進(jìn)行存儲升熊，先去判斷蘋果返回的這個(gè)applicationUsername是否為nil 如果為nil,去判斷傳入的這個(gè)平臺訂單號是否有值俄烁，如果有，直接使用這個(gè)值（一般走購買流程级野，這個(gè)值都是有的即可页屠，如果是走的漏單流程，applicationUsername 為nil 且此時(shí)是不傳入平臺訂單號的蓖柔，這時(shí)候就應(yīng)該在發(fā)起購買的之后存儲這個(gè)訂單號辰企，具體存儲可以將拉起購買傳進(jìn)來的平臺order作為值，然后transaction.transactionIdentifier作為key（注：實(shí)測當(dāng)憑證為key 存儲的話况鸣，在有訂閱類型商品的收會(huì)出現(xiàn)同一個(gè)商品不同時(shí)段憑證不一樣的情況牢贸，導(dǎo)致取不到存儲的order,因此通過transaction.transactionIdentifier（唯一事務(wù)id）來進(jìn)行存儲,這個(gè)實(shí)測確保是唯一的）存儲到某個(gè)目錄下,文件名可以用：平臺訂單號.plist的格式保存。所以在下次走漏單的流程時(shí)候蘋果返回applicatonUsername為nil 的镐捧，可以去遍歷存儲的plist,然后將鍵為該憑證的值取出來潜索，這就是與購買憑證匹配的平臺訂單號了。

二懂酱、第二種方法需要跟服務(wù)端交互竹习，也就是在拉起內(nèi)購的時(shí)候，在獲取到憑證的時(shí)候列牺，將憑證和傳進(jìn)來的平臺訂單號一起post到你們家后臺整陌，當(dāng)在獲取蘋果返回的applicationUsername為nil 的時(shí)候，通過憑證去后臺將這個(gè)平臺訂單號取回來就可以了瞎领。第二種方法需要進(jìn)行兩部交互有點(diǎn)繁瑣蔓榄。

問題二

在此前的文章中的這一段代碼，在實(shí)際運(yùn)營中出現(xiàn)過因?yàn)橛唵翁枮閚il 而無法刪除已經(jīng)成功的憑證默刚，不停向服務(wù)器發(fā)起訪問的問題，部分代碼如下：

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

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = nil;
NSArray *cacheFileNameArray = [fileManager contentsOfDirectoryAtPath:[SandBoxHelper iapReceiptPath] error:&error];

if (error == nil) {
    
    for (NSString *name in cacheFileNameArray) {
        
        if ([name hasSuffix:@".plist"]){
            //如果有plist后綴的文件逃魄，說明就是存儲的購買憑證
            NSString *filePath = [NSString stringWithFormat:@"%@/%@", [SandBoxHelper iapReceiptPath], name];
            
            [self sendAppStoreRequestBuyPlist:filePath trans:transaction];
        }
    }
    
} else {
    
    [RRHUD hide];
    
 }
}



  #pragma mark -- 根據(jù)訂單號來移除本地憑證的方法
-(void)successConsumptionOfGoodsWithOrder:(NSString * )cpOrder{

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError * error;
if ([fileManager fileExistsAtPath:[SandBoxHelper iapReceiptPath]]) {
    
    NSArray * cacheFileNameArray = [fileManager contentsOfDirectoryAtPath:[SandBoxHelper iapReceiptPath] error:&error];
    
    if (error == nil) {
        
        for (NSString * name in cacheFileNameArray) {
            
            NSString * filePath = [NSString stringWithFormat:@"%@/%@", [SandBoxHelper iapReceiptPath], name];
            
            [self removeReceiptWithPlistPath:filePath ByCpOrder:cpOrder];
            
        }
    }
}

}

#pragma mark -- 根據(jù)訂單號來刪除 存儲的憑證
-(void)removeReceiptWithPlistPath:(NSString *)plistPath ByCpOrder:(NSString *)cpOrder{

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError * error;
NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithContentsOfFile:plistPath];
NSString * order = [dic objectForKey:@"order"];

if ([cpOrder isEqualToString:order]) {
    
    //移除與游戲cp訂單號一樣的plist 文件
    BOOL ifRemove =  [fileManager removeItemAtPath:plistPath error:&error];
    
    if (ifRemove) {
        
        NSLog(@"成功訂單移除成功");
        
    }else{
        
        NSLog(@"成功訂單移除失敗");
    }
    
}else{
    
    NSLog(@"本地?zé)o與之匹配的訂單");
 }
}

以上代碼的話會(huì)在獲取不到訂單號的時(shí)候刪除不了本地的已經(jīng)成功的訂單荤西。會(huì)導(dǎo)致 -(void)checkIAPFiles:(SKPaymentTransaction *)transaction這個(gè)方法始終判斷這個(gè)目錄下有文件。在購買的時(shí)候不停地向服務(wù)端發(fā)起訪問，加劇服務(wù)器壓力邪锌。

針對以上的問題勉躺，我簡化了一些流程，考慮到蘋果內(nèi)購有獨(dú)有的漏單操作觅丰。其實(shí)不必要存儲憑證也可以實(shí)現(xiàn)補(bǔ)單流程饵溅。優(yōu)化代碼我貼出來，具體關(guān)于applicationUsername為nil 的處理妇萄，大家可以根據(jù)需求從中選擇一個(gè)來進(jìn)行處理蜕企。至于文件我也會(huì)更新到github ,鏈接請看評論，有需要大家可以下載使用冠句。至于該文件中的一些block 或者你們看不懂的回調(diào)其實(shí)跟我的業(yè)務(wù)有關(guān)轻掩，因?yàn)槲沂菍慡DK給別人用的所以要回調(diào)購買的結(jié)果給研發(fā)做判斷進(jìn)行發(fā)貨操作。不關(guān)乎你們的內(nèi)購邏輯懦底。一下是優(yōu)化之后的內(nèi)購代碼 :

代碼可能粘貼不齊，細(xì)節(jié)調(diào)整之后和最新的單例類內(nèi)購文件已經(jīng)同步到GitHub 了杆查，如有需要可以去gitHud 直接下載源文件扮惦，建議自己揣摩清楚之后再參考或者引入自己的項(xiàng)目，之所謂知其所以也要知其所以然根灯。另外在-(void)getAndSaveReceipt:(SKPaymentTransaction *)transaction径缅；方法里面沒有對applicationUsername為nil 做處理，大家可以跟我說的哪兩種思路進(jìn)行解決烙肺，我在這里就不代碼演示了纳猪。大家多動(dòng)腦~ github鏈接如下：https://github.com/jiajiaailaras/ULIPAPurchase
