IOS客户端内购(IAP)简单总结

近期需要用到所以稍微研究,整理了一下,囧

需要注意的几点: 

1.导入StoreKit框架 

2.确保product ID惟一且与IITUNNES CONNECT中的一致

3.请确保plist文件中的Bundle identifier与ITunes Connet中的Bundle ID一致

4.虚拟机好像跑不起来

5.iTunes Connect 中product ID 的分配上限为10W个

6.内购不分区域,可以在任何地方购买,即使应用在不分区域没上架

7.越狱设备可能无法使用(我的机子就没通过,囧)

8.沙盒测试的话,请使用iTunes Connect Test User的账号

下面是个流程图(闲话:这张图从别而网站扒下来的，不过不记得是从哪个网站扒下来的了)

以下涉及到的分别有

(1)框架

       <StoreKit/StoreKit.h>

(2)1个类和3个Delegate

         Class:SKProductsRequest

      Delegate:<SKPaymentTransactionObserver,SKProductsRequestDelegate,SKRequestDelegate]]]]>

下面上几段核心代码

.h中

#import <StoreKit/StoreKit.h>@interface IAPUnity : NSObject<SKPaymentTransactionObserver,SKProductsRequestDelegate,SKRequestDelegate>@property(retain,nonatomic)NSArray* products;       //产品列表@property(retain,nonatomic)NSSet* productIdf;       //产品标记符@property(retain,nonatomic)SKProductsRequest* request;  //用于请求相关信息///获取商店信息-(void)requestStart;///初始化- (id)initProductIdf:(NSSet*)productIdf;///购买-(void)buyProduct;///恢复交易-(void)restorer;@end

.m

#import "IAPUnity.h"@interface IAPUnity ()@property(retain,nonatomic)SKProduct* product;@end@implementation IAPUnity- (id)initProductIdf:(NSSet*)productIdf{    self = [super init];    if (self) {        self.productIdf=productIdf;        [self getProducts];    }    return self;}-(void)getProducts{    _request=[[SKProductsRequest alloc]initWithProductIdentifiers:_productIdf];}-(void)requestStart{    [_request setDelegate:self];    ///请求数据    [_request start];}#pragma SKProductsRequestDelegate - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{    ///判断用户是否禁用内购功能    if ([SKPaymentQueue canMakePayments]) {        NSLog(@"%@",response.products);        //得到产品列表        self.products=response.products;        }        ///获取成功列表成功,并且取到第0个的相关信息    if ([response.products count]>0) {        self.product=[response.products objectAtIndex:0];        NSLog(@"产品本地标题:%@",[self.product localizedTitle]);        NSLog(@"产品描述:%@",self.product.localizedDescription);        NSLog(@"产品价格:%@",self.product.price);        NSLog(@"产品标识:%@",self.product.productIdentifier);    }            ///发生错误的时候输出错误信息    for (NSString *invalidProductId in response.invalidProductIdentifiers)    {        NSLog(@"Invalid product id: %@" , invalidProductId);    }}-(void)buyProduct{    if (self.product) {                if ([SKPaymentQueue canMakePayments]) {            SKPayment* payment=[SKPayment paymentWithProduct:self.product];            ///为支付队列增加一个观察者            [[SKPaymentQueue defaultQueue]addTransactionObserver:self];            ///增加了一个观察者到付款队列中            [[SKPaymentQueue defaultQueue]addPayment:payment];        }    }}-(void)restorer{        [[SKPaymentQueue defaultQueue]restoreCompletedTransactions];}// Sent when the transaction array has changed (additions or state changes).  Client should check state of transactions and finish as appropriate.- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{    for (SKPaymentTransaction* transaction in transactions) {        switch (transaction.transactionState) {            case SKPaymentTransactionStatePurchasing:            {                NSLog(@"购买中");            }                break;            case SKPaymentTransactionStatePurchased:            {                NSLog(@"SKPaymentTransactionStatePurchased");                NSLog(@"%@",[[NSString alloc]initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding]);                NSString* temp=[[NSString alloc]initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding];                UIAlertView* alertView=[[UIAlertView alloc]initWithTitle:@"提示" message:@"内购成功" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];                [alertView show];                NSLog(@"BASE64:%@",[self encode:temp.UTF8String length:temp.length]);                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];            }                break;            case SKPaymentTransactionStateFailed:            {                if (transaction.error.code!=SKErrorPaymentCancelled) {                    NSLog(@"Failed....%d",transaction.error.code);                    NSLog(@"%@",transaction.error.localizedDescription);                }                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];                        }                break;            case SKPaymentTransactionStateRestored:            {                [[SKPaymentQueue defaultQueue]finishTransaction:transaction];            }                break;            default:                break;        }    }}@end

之前的BASE64函数有点问题，所以删掉了,换了一个

下面是 transaction.transactionState的几种状态

     SKPaymentTransactionStatePurchasing,    // 这一个是应用商店是正在处理交易的状态     SKPaymentTransactionStatePurchased,     // 这一个是应用商店成功处理付款的状态     SKPaymentTransactionStateFailed,        // 这儿是应用商店处理失败的状态     SKPaymentTransactionStateRestored       // 这个是应用商店恢复之前的状态

中间遇到的问题

(1)问题:使用SKPayment的paymentWithProductIdentifier无法连接上APP STORE导致无法进行购买（网络不好也可能出现连接不上的情况）

     解决方法:改用SKPayment的paymentWithProduct方法

(2)问题:购买时，登陆成功后提示 [environment:sandbox] ,导致无法成功购买

     解决方案:我在这,就是回到ITUNESCONNETION中重新Add了1个账号(美国地区的,中国的试了几个都不行),回到设备上注销掉之前的账号和关掉APP STORE,重新登陆即可

(3)问题:-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response 中 response.invalidProductIdentifiers count>0的情况。

     解决方案:我换了一台非越狱设备,就正常了
