我创建了一个应用内购买，以从应用中删除广告。在我的测试应用程序中，它工作正常，但现在我已将它添加到主应用程序，它将无法正常工作。我可以很好地完成购买选项，我收到消息说“你已经完成了设置，你的购买成功了”但是在应用程序崩溃之后会立即进行。
这是我的代码：

@IBOutlet var activityIndicator: UIActivityIndicatorView!
@IBOutlet var restorePurchasesReference: UIButton!

var product: SKProduct?
var productID = "com.joshbury.GTAVCheats.RemoveAds"
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
statusLabel.isHidden = true
statusLabel.text = "Remove ads to enjoy an ad free experience!"
activityIndicator.isHidden = true
disableRestorePurchasesButton()
disableRemoveAdsButton()
SKPaymentQueue.default().add(self)
getPurchaseInfo()
}

super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
