在App Purchase中偶尔会导致崩溃

时间：2015-12-15 12:22:30

标签： ios swift crash in-app-purchase crash-reports

我在互联网上寻求帮助，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：

引用崩溃的方法如下：

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
  }
 }
}

我不确定从哪里开始，因为paymentQueue: updatedTransactions中的代码对我来说看起来不错，实际上直接来自IAP上的Ray Wenderlich教程：http://www.raywenderlich.com/105365/in-app-purchases-tutorial-getting-started

这尤其令我困惑： function signature specialization <Arg[0] = Dead and Owned To Guaranteed, Arg[1] = Owned To Guaranteed>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，还是我的代码？

提前致谢！

修改

为了回应Alpesh的回答，我的功能现在看起来像这样：

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
  }
 }

} }
