Transaktion staute in der Warteschlange in der Mitte des Kaufs

Question

Ich teste meine in App-Kauf mit Test accound und woher gut. Ich erfahre zufällig ein Problem. Ich war in der Mitte des Kaufs, die Warnung ging weiter "Möchten Sie kaufen ..." und ich drückte auf HOME-Taste, als ich wieder Anwendung begann, löschte es nicht Warteschlange? Also fing ich an, Pop-up zu empfangen, um mich anzumelden ... es war in der Warteschlange stecken geblieben. Ich brauche Hilfe, um zu implementieren, wenn App beendet wird, um Warteschlange automatisch zu löschen. Wenn also jemand dafür Code schreiben kann. Tnx

Ich glaube, ich löste das, indem ich Beobachter in appDelegate setzte.

import UIKit 
import StoreKit 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate { 

var window: UIWindow? 

var transactionObserver: PurchaseViewController! 



func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 
    transactionObserver = PurchaseViewController() 
    SKPaymentQueue.defaultQueue().addTransactionObserver(transactionObserver) 

    // Override point for customization after application launch. 
    return true 
} 

func applicationWillResignActive(application: UIApplication) { 
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. 
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game. 
} 

func applicationDidEnterBackground(application: UIApplication) { 
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. 

    transactionObserver = PurchaseViewController() 
    SKPaymentQueue.defaultQueue().removeTransactionObserver(transactionObserver) 
} 

func applicationWillEnterForeground(application: UIApplication) { 
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background. 
} 

func applicationDidBecomeActive(application: UIApplication) { 
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. 
} 

func applicationWillTerminate(application: UIApplication) { 
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. 
    transactionObserver = PurchaseViewController() 
    SKPaymentQueue.defaultQueue().removeTransactionObserver(transactionObserver) 
}
