接入

使用RMStore。

1、使用RMStore的接入步骤

1、在Podfile内添加pod 'RMStore'并pod install;
2、实现并设置接口RMStoreReceiptVerificator；
3、在应用启动时调用接口 
- (void)requestProducts:(NSSet*)identifiers
                success:(RMSKProductsRequestSuccessBlock)successBlock
                failure:(RMSKProductsRequestFailureBlock)failureBlock
4、在支付时调用接口
- (void)addPayment:(NSString*)productIdentifier
              user:(NSString*)userIdentifier
           success:(void (^)(SKPaymentTransaction *transaction))successBlock
           failure:(void (^)(SKPaymentTransaction *transaction, NSError *error))failureBlock

2、详细解析

步骤1，引入第三方库。
步骤2，RMStoreReceiptVerificator类是验证凭据的有效性。
实现接口RMStoreReceiptVerificator，并向服务器请求验证凭据的有效性，等返回后回调RMStore。

@implementation IAPReceiptVerificator
- (void)verifyTransaction:(SKPaymentTransaction*)transaction
                  success:(void (^)())successBlock
                  failure:(void (^)(NSError *error))failureBlock
{
    RequestSuccessResponseBlock success=^(NSDictionary *responseDic){
        NSLog(@"success");
        if (successBlock) {
            successBlock();
        }
    };
    RequestFailResponseBlock fail=^(NSError *error){
        NSLog(@"fail");
        if (failureBlock) {
            failureBlock(error);
        }
    };
    NSData* data = [NSData dataWithContentsOfURL:[NSBundle mainBundle].appStoreReceiptURL];
    NSMutableDictionary *params = [NSMutableDictionary dictionary];
    params[@"receipt-data"] = [data base64EncodedStringWithOptions:0];
    [[HTTPClient sharedHTTPClient] requestWithParameters:params
                                                  withPath:@"pay/apple"
                                               withRESTful:POST_REQUEST
                                          withSuccessBlock:success
                                             withFailBlock:fail];
}
