我正在用测试软件测试我的应用内购买情况，一切都很好。我不小心发现了一些问题。我正在购买过程中，警报继续显示“您是否要购买...”，然后按了HOME按钮，当我再次启动应用程序时，它没有清除队列吗？所以我开始收到弹出式窗口以供登录...它被卡在队列中。我需要帮助，如何在应用终止时实施，以自动清除队列。因此，如果有人可以为此发布代码。特纳克斯

我想我通过将观察者放在appDelegate中解决了这个问题。
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)
}
}
