This problem occurs to me: Purchase a subscription through a movie with a lock. I click on the camera button. The subscription view opens. I make my purchase: I display an error message (but the purchase is still successful).
func subscribe(sub: SubscriptionType) {
DispatchQueue.main.async { let _ = MBProgressHUD.standardHud(over: self.managedView) }
FS2Recipes.subscribe(sku: sub.sku()).then { _ in
self.subscribed()
}.catch { error in
debugPrint("Error \(error.localizedDescription)")
let alert = UIAlertController(title: "Ooops", message: "There was an error processing your purchase. Try again later!", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak self] _ in
self?.dismiss()
}))
self.present(alert, animated: true, completion: nil)
}.always {
DispatchQueue.main.async { let _ = MBProgressHUD.hide(for: self.managedView, animated: true) }
}
}
Error
