05-内购

1、什么样的应用需要使用内购?

需要使用内购:在APP中卖的东西是自己APP中的内容或者是只能在自己APP消费(常见的内购有:游戏中的道具、音频、视频)

不需要使用内购:常见的应用类型有:电商类、美团、饿了么

2、内购步骤

2-1:在iTunes Connect中的功能选项卡中有APP内购买项目中添加你要卖的产品(如下图:)

2-2:下面就是代码部分

2-2-1:需要导入的头文件

//内购头文件
#import 

2-2-2:内购代理方法


#pragma mark - SKProductsRequestDelegate 代理方法
/**
 * 获取可卖产品
 */
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response;

#pragma mark - SKPaymentQueue回调方法
/*
 队列中的交易发生改变时,就会调用该方法
 */
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

2-3:获取内购产品方式

2-3-1:方式一:灵活配置

    为了把内购产品在APP中展示出来,最好把我们在iTunes Connect中的  功能  选项卡中有  APP内购买项目 中添加你要卖的产品ID告诉  自己的服务器 。(优点:当想要修改产品的价格时,只需要服务器修改和iTunesConnect修改的一致就可以实现了,达到了动态修改的目的

2-3-2:方式二:配置写死

    只需要在客服端代码中把产品ID写到一个数组即可

2-4:我们的项目获取内购产品是采用的方式一

第一步:从自己的服务器获取内购产品信息列表,主要是为了显示,便于选择购买(如下图所示:)
第二步:向自己的服务器发起请求来获取,订单信息。
第三步:最后把内购添加到交易队列中
第四步:然后付款支付
第五步:监听支付结果,进行相应处理
第六步:进行支付结果验证:
1、服务器验证:优点是安全
2、客户端验证:缺点是不安全

3、内购主要代码

//1、开始内购
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
   
    //传入商品下标,来访问自己的服务器发送请求
    [self requestProductIndex:(int)indexPath.row];
    
}
#pragma mark - 传入商品下标,来访问自己的服务器发送请求
/**
 * 传入商品下标,来访问自己的服务器发送请求
 */
- (void) requestProductIndex:(int) productIndex {

    //1、获取商品模型(vipMsgs内购信息列表数组)
    BeanAsset *asset = self.vipMsgs[productIndex];
    //    RWLog(@"%@", asset);
    //2、想自己的服务器发送请求
    [self requestProductMsgBeanAsset:asset];

}
#pragma mark - 请求 商品订单信息
- (void)requestProductMsgBeanAsset:(BeanAsset *)vipAsset {
    
    NSString *priceStr = [NSString stringWithFormat:@"%@", [vipAsset getPrice]];
    
    NSString *idStr = [NSString stringWithFormat:@"%@", [vipAsset getId]];
    
    
    [BusinessInterfaceBz buyWithNSString:priceStr withNSString:idStr withHttpIResult:self];
}
//请求商品订单信息成功回调
//3、向【苹果服务器发送购买请求】
                [weakSelf showOkayCancelAlertMessage:showString indexPath:weakSelf.productIndex];
//把交易添加到队列中
//1、获取可卖商品
        [weakSelf buyProductsWithIndexPath:indexPath];
//2、
#pragma mark - 获取可卖商品
/**
 * 获取可卖商品
 */
- (void)buyProductsWithIndexPath:(int) indexPath {
    //1.1、当从 【苹果服务器】中取到了可卖商品
    if (self.products.count) {
        
        //1、取出模型(苹果代理方法中会把我们在iTunes中添加的内购商品返回来,在products数组中)
        SKProduct *product = self.products[indexPath];
        //2、购买商品
        [self buyProduct:product];
        
    }else {
        
        //1.2、当没有从【苹果服务器】中获取到可卖的商品
        //            [self productsMessageRequest];
    }
}

//3、最后把交易添加到交易队列中
#pragma mark - 购买商品
- (void)buyProduct:(SKProduct *) product {
    
    //1、创建票据
    SKPayment *payment = [SKPayment paymentWithProduct:product];
    
    //2、将票据 添加到 交易队列中
    [[SKPaymentQueue defaultQueue] addPayment:payment];
    
}

4、监听苹果的代理方法来获取内购的商品

#pragma mark - SKProductsRequestDelegate 代理方法
/**
 * 获取可卖产品
 */
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    self.products = response.products;
    //1、展示商品
    self.products = [response.products sortedArrayWithOptions:NSSortConcurrent usingComparator:^NSComparisonResult(SKProduct *obj1, SKProduct *obj2) {
        
        //返回的数组 按钮【价格排序】
        return [obj1.price compare:obj2.price];
    }];
    
}

5、监听交易返回结果

#pragma mark - SKPaymentQueue回调方法
/*
 队列中的交易发生改变时,就会调用该方法
 */
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
    
    /*
     SKPaymentTransactionStatePurchasing,    正在购买
     SKPaymentTransactionStatePurchased,     已经购买(购买成功)
     SKPaymentTransactionStateFailed,        购买失败
     SKPaymentTransactionStateRestored,      恢复购买
     SKPaymentTransactionStateDeferred       未决定
     */
    for (SKPaymentTransaction *transation in transactions) {
        switch (transation.transactionState) {
            case SKPaymentTransactionStatePurchasing:
                NSLog(@"用户正在购买");
                break;
                
            case SKPaymentTransactionStatePurchased:
                NSLog(@"购买成功,将对应的商品给用户");
                
                [self completeTransaction:transation];
                break;
                
            case SKPaymentTransactionStateFailed:
                NSLog(@"购买失败,告诉用户没有付钱成功");
                [self failedTransaction:transation];
                break;
                
            case SKPaymentTransactionStateRestored:
                NSLog(@"恢复商品,将对应的商品给用户");
                [self restoreTransaction:transation];
                break;
                
            case SKPaymentTransactionStateDeferred:
                NSLog(@"未决定");
                break;
            default:
                break;
        }
    }
    
}

6、小结(小心被拒)

在内购时,苹果审核时是不允许强制用户登录的,也就是用户时游客时也是可以进行内购的:

#pragma mark - 通过buttonIndex来判断点击了什么按钮(警告框从底部弹出)
-(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    switch (buttonIndex) {
        case 0:
            //跳转到【注册界面】
            [self skipRegisterInterface];
            break;
        case 1:
            //游客模式购买
            [self requestProductIndex:self.productIndex];
            break;
        case 2:
            NSLog(@"取消购买");
            break;
        default:
            break;
    }
}
