}

break;

default:

break;

}

}

}

//交易结束

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

NSLog(@"交易结束");

[[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}

- (void)dealloc{

[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];

}

-(void)verifyPurchaseWithPaymentTransaction:(NSNumber*)resultState{

//从沙盒中获取交易凭证并且拼接成请求体数据

NSURL *receiptUrl=[[NSBundle mainBundle] appStoreReceiptURL];

NSData *receiptData=[NSData dataWithContentsOfURL:receiptUrl];

}

```

四.注意事项

1.内购必须用真机测试

2.测试时必须退出App Store自己的Apple ID，登录沙盒的测试Apple ID .

3.本身请求美国服务器就慢，为防止审核人员误解，我们需要在购买时加载动画。
