SKPaymentQueue.defaultQueue().addPayment(payment)在VC Swift之间移动时崩溃

IAP正在运行,但当我在视图之间移动并返回到IAP VC时,应用程序崩溃了 SKPaymentQueue.defaultQueue().addPayment(payment) ERROR: EXC_BAD_ACCESS

我找到了解决方案,你需要清理SKPaymentQueue一下viewWillDisappear

更新Swift 4.2

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    SKPaymentQueue.default().remove(self)
}

斯威夫特2.3

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated: animated)
    SKPaymentQueue.defaultQueue().removeTransactionObserver(self)
}
