应用内购买成功导致部分用户崩溃

【中文标题】应用内购买成功导致部分用户崩溃【英文标题】：Successful In App Purchase causes crash for some users 【发布时间】：2016-03-08 12:21:39 【问题描述】：我有一个只有一个 IAP 的应用程序，它允许用户解锁完整的游戏。对于少数用户，他们成功购买了 IAP，但当他们点击继续时，游戏崩溃了。重新启动应用程序并尝试加载他们保存的游戏时，应用程序再次崩溃。删除并重新安装应用程序也没有任何区别。
这是一个崩溃报告：

它崩溃的方法是：

let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC)))
dispatch_after(delayTime, dispatch_get_main_queue())

我使用了一个 IAPHelper.swift 类，该类取自 Ray Wenderlich 的 IAP 教程：http://www.raywenderlich.com/105365/in-app-purchases-tutorial-getting-started
为了提供尽可能多的信息，我将在这个类下面列出完整的内容以及来自 UnlockGameViewController 的相关代码，从中可以看到解锁游戏的选项：

来自 UnlockGameViewController 的通知方法：

func productPurchased(notification: NSNotification)
let productIdentifier = notification.object as! String
for (index, product) in products.enumerate()
if product.productIdentifier == productIdentifier
// Only one IAP so we can assume this is the Unlock Full Game IAP
activitySpinnerStop()
agent.gameUnlocked = true // sets the bool that the game has now been unlocked
if openedFromMain == true
showAlertWith(Localization("GameUnlockedAlertTitle"), message: Localization("GameUnlockedAlertMessage"))
noThanksButton.setTitle("Return to Main Menu", forState: UIControlState.Normal)
else
showAlertWith(Localization("GameUnlockedAlertTitle"), message: Localization("GameUnlockedAlertMessage2"))
// When a transaction fails, this notification fires
func transactionFailed(notification: NSNotification)
activitySpinnerStop()
showAlertWith(Localization("TransactionFailedAlertTitle"), message: Localization("TransactionFailedAlertMessage"))
// When we cannot connect to iTunes to retrieve the IAPs, this notification fires
func cannotConnect(notification: NSNotification)
activitySpinnerStop()
showAlertWith(Localization("NoConnectionAlertTitle"), message: Localization("NoConnectionAlertMessage"))
确实有两个问题：1）为什么它首先会崩溃？ 2）为什么他们不能删除应用程序，重新安装和恢复？特别是在付款完成时。
老实说，如果我的用户能够毫无问题地删除、重新安装和恢复，他们可以忍受初始崩溃。一位用户报告说，在他的 iPhone 崩溃后，他在 iPad 上下载了游戏，并且能够很好地恢复交易。所以这让我相信这可能是使用 NSUserDefaults 保存在崩溃设备上的损坏数据的问题？类似于这个问题的东西： iOS - strange crash on in App purchase restore function
这是我的第一个应用程序，我对调试的经验确实很少。如果解决方案本身没有出现，我们将非常欢迎您提供一些有关如何调试此问题的指导。我不知道如何在我的设备上重现一个似乎只有在实时应用上进行 IAP 时才会发生的问题。
【问题讨论】：
你为什么使用dispatch_after？这种事情总是让我的蜘蛛侠感觉刺痛 这个问题我已经有一段时间了，之前在这里询问过。这被建议作为答案，公平地说，它大大减少了崩溃的数量：***.com/questions/34289204/… 可能是 Game Center 身份验证挂起并导致整个应用程序崩溃？ "Breadcrumb Trail: (倒序秒数) 14 GC Framework: startAuthenticationForExistingPrimaryPlayer" 【参考方案1】：我无法告诉你出了什么问题...所有接缝都还好，只是一点评论...也许在您的一种方法中增加一个“守卫”就可以了。 这是你的方法：
public func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse)
print("Loaded list of products...")
let products = response.products
completionHandler?(success: true, products: products)
clearRequest()
// debug printing
for p in products
print("Found product: \(p.productIdentifier) \(p.localizedTitle) \(p.price.floatValue)")
Apple 建议检查 response.products 是否不为零 if ([response.products count] > 0)... https://developer.apple.com/library/ios/technotes/tn2387/_index.html
所以..有这样的东西会更好..
func productsRequest(request: SKProductsRequest!, didReceiveResponse response: SKProductsResponse!)
if response.products.count != 0
.....
您还可以进行额外检查..如果响应中不是invalidProductIdentifiers
。这种情况更有可能发生在您创建的真实应用程序中 并不时删除 IAP 产品，而您的应用要求 不再存在的产品 ID... 更多内容：http://www.appcoda.com/in-app-purchase-tutorial/
所以..在上面的方法中你也可以添加
func productsRequest(request: SKProductsRequest!, didReceiveResponse response: SKProductsResponse!)
...
if response.invalidProductIdentifiers.count != 0
println(response.invalidProductIdentifiers.description)
//do something
【讨论】：
谢谢托尼，这些链接非常有用。似乎我没有实施您链接的 Apple 文档中详述的几个最佳实践。我会仔细检查并确保我的应用程序符合要求，如果它解决了问题，我会将这个答案标记为正确。以上是关于应用内购买成功导致部分用户崩溃的主要内容，如果未能解决你的问题，请参考以下文章
