mainBundle上的appStoreReceiptURL总是返回nil

本文介绍了mainBundle上的appStoreReceiptURL总是返回nil的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

此方法appStoreReceiptURL是SKPaymentTransaction上已弃用的transactionReceipt方法的替代品。而且每个人都说只是使用这个调用：

This method appStoreReceiptURL is the replacement for the deprecated transactionReceipt method on SKPaymentTransaction. And everyone says to just use this call instead:

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

如果有收据，这应该会返回一个收据。但对我来说没有一个，因为这个值是零，而且据我所知，它不应该是。我在iOS 7上运行并且已经完成了一些应用内购买（设备上的沙箱）。现在我正在尝试添加另一个应用内购买，自动续订订阅，我需要深入了解收据以获取订阅到期日期。但是我无法通过这个简单的步骤，因为价值总是为零。

This is supposed to return a url to a receipt if there is one. But for me there isn't one, as this value is nil, and as far as I can tell it shouldn't be. I'm running on iOS 7 and have done a few in-app purchases (sandbox on the device). Now I'm trying to add another in-app purchase, an auto-renewing subscription, and I need to dig into the receipt to get the subscription expiration date. But I can't get past this simple step because the value is simply always nil.

有谁知道为什么？

推荐答案

有点晚了，但它可能对某人有用：

A bit late, but it may be of use to someone:

-(void) someMethod { NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL]; if ([[NSFileManager defaultManager] fileExistsAtPath:[receiptUrl path]]) { NSData *ios7ReceiptData = [NSData dataWithContentsOfURL:receiptUrl]; //Do stuff } else { NSLog(@"iOS 7 AppReceipt not found %@, refreshing...",iapID); SKReceiptRefreshRequest *refreshReceiptRequest = [[SKReceiptRefreshRequest alloc] initWithReceiptProperties:@{}]; refreshReceiptRequest.delegate = self; [refreshReceiptRequest start]; } } - (void)requestDidFinish:(SKRequest *)request { if([request isKindOfClass:[SKReceiptRefreshRequest class]]) { //SKReceiptRefreshRequest NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL]; if ([[NSFileManager defaultManager] fileExistsAtPath:[receiptUrl path]]) { NSLog(@"App Receipt exists"); //Do stuff } else { NSLog(@"Receipt request done but there is no receipt"); // This can happen if the user cancels the login screen for the store. // If we get here it means there is no receipt and an attempt to get it failed because the user cancelled the login. //[self trackFailedAttempt]; } } }
