ios - 交易在购买过程中陷入队列

Question

我正在使用测试账户测试我的应用内购买，一切都很好。我无意中发现了一些问题。我正在购买中，警报继续“您想购买...”，然后我按下主页按钮，当我再次启动应用程序时，它没有清除队列？所以我开始收到登录弹出窗口...它被困在队列中。我需要帮助，如何实现应用程序终止时自动清除队列。因此，如果有人可以发布代码。 TNx

我想我通过将观察者放入 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)
}
