你好，我有工作的应用程序，当用户点击购买限制视图控制器（第一次点击）用户买了一切都好，但当用户回到主控制器，并再次购买限制视图控制器和用户点击购买IAP做双重交易和用户也再次去主控制器，并再次购买限制视图控制器时，点击购买IAP做三重交易..我如何解决这个问题我的代码在下面。Swift IAP multiple交易时返回并再次查看控制器

purchaseManager.delegate = self
purchaseManager.loadPaymentInfo()
if let path = NSBundle.mainBundle().pathForResource("PurchaseID", ofType: "plist")
{
if let fileItems = NSArray(contentsOfFile: path)
{
items = fileItems
}
}
let mainQueue = NSOperationQueue.mainQueue()
NSNotificationCenter.defaultCenter().addObserverForName(purchaseManager.productsLoadedNotification, object: nil, queue: mainQueue) { _ in
self.tableView.reloadData()
}
}
// MARK: - TableView delegate
func numberOfSectionsInTableView(tableView: UITableView) -> Int
{
return items.count
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
var numberOfItems = 0
if let purchaseItems = items[section] as? [String]
{

}
return numberOfItems
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{

{

if purchaseManager.productsAreLoaded()
{
cell.accessoryView = nil
cell.titleLabel.text = purchaseManager.getProductTitle(productID)
cell.priceLabel.text = purchaseManager.getProductPrice(purchaseItems[indexPath.row])
}
else
{

cell.accessoryView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)

}
}
}
return cell
}
func giveLimits(purhased : NSString) {
let postEndpointLost:NSString = "http://bla.com/"
user.sharedInstance.apiRequest(postEndpointLost as String, completionHandler: { (success, message) -> Void in
if(success == 1){
dispatch_async(dispatch_get_main_queue()){

}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)

{
purchaseManager.buyProduct(purchaseItems[indexPath.row])
}
}
}
@IBAction func restoreButtonSelector(sender: AnyObject) {
purchaseManager.restorePurchases()
}
// MARK: - Purchase Manager delegate
func refreshList()
{
self.tableView.reloadData()
}
func transactionIsActive()
{
let alert = UIAlertController(title: "", message: "Transaction is already in progress. Please wait to finish.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: { alertAction in
self.tableView.reloadData()
alert.dismissViewControllerAnimated(true, completion: nil)
}))
self.presentViewController(alert, animated: true, completion: nil)
}
func restoreCompleted()
{
let alert = UIAlertController(title: "", message: "Restore completed.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: { alertAction in
self.tableView.reloadData()
alert.dismissViewControllerAnimated(true, completion: nil)
}))
self.presentViewController(alert, animated: true, completion: nil)
}
}
为每个负载buyviewcontroller +1计数这个输出例如
Transaction in Progress
Transaction in Progress
Transaction in Progress
Transaction in Progress
我想也许输出的例子就需要明确出头的时候userclick购买限制视图控制器我需要你的帮助谢谢！
什么想法？我该如何解决它？我认为在购买限制视图控制器重写func viewDidLoad（）{}里面错了吗？当用户再次购买限制视图控制器重复某些事情？ – SwiftDeveloper
