这是我第一次进行应用内购买。当我在我的设备（iPod 4 Touch）上测试时，一切似乎都运行良好，但是在将应用程序提交到App Store之后，我下载了它并且应用程序崩溃（或者更确切地说，我认为，当我按下时，中止做异常）尝试进行购买的按钮。甚至没有Apple的确认窗口（“你真的想以0.99美元购买x吗？”）。
以下代码似乎崩溃了：
-(void) unlockButtonTapped:(id)sender
{
iapLevel = selectedLevel;
int productIndex = selectedLevel - 1;
if (productIndex == 4) productIndex = 0;
if ((productIndex >= 4) || (productIndex <= -1)) return;
// crash is likely in the following lines
SKProduct *product = (SKProduct *) _myProducts[productIndex];
SKMutablePayment *payment = [SKMutablePayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
Eariler，我执行以下操作来获取产品标识符：
NSURL *url = [[NSBundle mainBundle] URLForResource:@"product_identifiers" withExtension:@"plist"];
NSArray *productIdentifiers = [NSArray arrayWithContentsOfURL:url];
[self validateProductIdentifiers:productIdentifiers];
哪个电话：
-(void) validateProductIdentifiers:(NSArray *)productIdentifiers
{
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithArray:productIdentifiers]];
productsRequest.delegate = self;
[productsRequest start];
}
哪个电话：
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
self.myProducts = response.products; // set _myProducts NSArray
for (NSString *invalidIdentifier in response.invalidProductIdentifiers) {
// Handle any invalid product identifiers.
}
[self displayStoreUI]; // Custom method
}
最后，崩溃日志显示以下内容：

崩溃似乎来自：
SKProduct *product = (SKProduct *) _myProducts[productIndex];
错误是因为productIndex超出范围。您要求的产品索引高于_myProducts数组中的对象数。
您需要分析填充_myProducts的方式并调整逻辑，以使productIndex不能大于数组。
