在应用程序购买导致偶尔崩溃
我在互联网上搜索了这方面的帮助，但无济于事。 我的应用程序在应用程序商店上运行，并且少数用户报告应用程序冻结并在进行In App Purchase后崩溃（我的游戏中唯一的IAP，它基本上解锁了完整版本）。 即使他们重新启动设备并尝试继续运行，它也会再次崩溃。 我无法重现崩溃 – 这是崩溃报告：

public func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { for transaction in transactions { switch (transaction.transactionState) { case .Purchased: completeTransaction(transaction) break case .Failed: failedTransaction(transaction) break case .Restored: restoreTransaction(transaction) break case .Deferred: break case .Purchasing: break } } }
我不确定在哪里开始真的像paymentQueue: updatedTransactions的代码paymentQueue: updatedTransactions对我来说看起来没问题，实际上直接来自IAP上的Ray Wenderlich教程： http ：//www.raywenderlich.com/105365/in-app- 购买教程，工具入门
这尤其让我感到困惑： function signature specialization 这是什么意思？
有人有什么想法吗？ 或者如何重现崩溃的建议？ 因为它只发生了几次，它可能与用户的设备或Apple的IAP处理有关，还是它绝对是我的代码？
提前致谢！
编辑：
为了回应Alpesh的回答，我的function现在看起来像这样：
public func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) { let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC))) dispatch_after(delayTime, dispatch_get_main_queue()) { for transaction in transactions { switch (transaction.transactionState) { case .Purchased: self.completeTransaction(transaction) break case .Failed: self.failedTransaction(transaction) break case .Restored: self.restoreTransaction(transaction) break case .Deferred: break case .Purchasing: break } } } }
由于内存问题，这是崩溃。 我认为你经过一段时间的延迟它就会像这样使用代码。 你也可以使用GCD Dispatch Timer
public func paymentQueue（queue：SKPaymentQueue，updatedTransactions transactions：[SKPaymentTransaction]）{
let delayTime = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC))) dispatch_after(delayTime, dispatch_get_main_queue()) { for transaction in transactions { switch (transaction.transactionState) { case .Purchased: completeTransaction(transaction) break case .Failed: failedTransaction(transaction) break case .Restored: restoreTransaction(transaction) break case .Deferred: break case .Purchasing: break } }
}}
