在购买过程中塞进队列中的事务

Question

我正在测试我的应用程序购买与测试帐户和所有好的地方。我不小心发现了一些问题。我在买东西的时候，警报继续说“你想买.”而我按了主页按钮，当我再次启动应用程序时，它没有清除队列？所以我开始收到消息来登录..。它被塞进了队列。我需要帮助，如何实现如果应用程序终止，自动清除队列。所以如果有些人能为之贴上代码。Tnx

我想我是通过在appDelegate中添加观察者来解决这个问题的。

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)
}


}
