I have a Consumable in-app-purchase in my OS X app that purchases a certain number of coins. However, the second time I purchase the consumable, I get an alert saying that the item has already been purchased and will be restored for free.
Why is this happening with a consumable in-app-purchase?
Here is my IAP code:
typealias RequestProductsCompletionHandler = ([SKProduct]?) -> Void
class IAPHelper: NSObject, SKProductsRequestDelegate{
private var productsRequest: SKProductsRequest?
private var completionHandler: RequestProductsCompletionHandler!
private let productIdentifiers: Set<String>
private var purchasedProductIdentifiers = Set<String>()
init(productIdentifiers: Set<String>){
self.productIdentifiers = productIdentifiers
super.init()
for identifier in productIdentifiers{
let productPurchased = NSUserDefaults.standardUserDefaults().boolForKey(identifier)
if productPurchased{
purchasedProductIdentifiers.insert(identifier)
}
}
}
func requestProducts(completionHandler: RequestProductsCompletionHandler){
self.completionHandler = completionHandler
productsRequest = SKProductsRequest(productIdentifiers: productIdentifiers)
productsRequest?.delegate = self
productsRequest?.start()
}
// MARK: SKProductsRequestDelegate
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
productsRequest = nil
let skProducts = response.products as! [SKProduct]
completionHandler(skProducts)
completionHandler = nil
}
func request(request: SKRequest, didFailWithError error: NSError) {
productsRequest = nil
print("Error: \(error)\nDescription: \(error.description)")
completionHandler(nil)
completionHandler = nil
}
func buyProduct(product: SKProduct){
let payment = SKPayment.paymentWithProduct(product) as! SKPayment
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().addPayment(payment)
}
func productPurchased(productIdentifier: String) -> Bool{
return purchasedProductIdentifiers.contains(productIdentifier)
}
}
extension IAPHelper: SKPaymentTransactionObserver{

Sinch client won't start and it doesn't give an error as to possible reasons.
let uuid = UIDevice.current.identifierForVendor?.uuidString
let client : SINClient = Sinch.client(withApplicationKey: appConstants.sinch_app_key, applicationSecret: appConstants.sinch_secret_key, environmentHost: appConstants.sinch_host, userId: uuid)
client.setSupportCalling(true)
//client.setSupportMessaging(true)
client.start()
client.delegate = self
client.call()?.delegate = self```
What worked was moving Sinch and it's initialisation to the AppDelegate and making it available to other ViewControllers.
So create the Sinch Client once
var sinchObject : SINClient!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let client : SINClient = Sinch.client(withApplicationKey: appConstants.sinch_app_key, applicationSecret: appConstants.sinch_secret_key, environmentHost: appConstants.sinch_host, userId: "id#id.com")
client.setSupportCalling(true)
client.setSupportMessaging(true)
client.delegate = self
client.start()
sinchObject = client
return true
}
func applicationWillTerminate(_ application: UIApplication) {
sinchObject?.stop()
}
func clientDidStart(_ client: SINClient!) {
print("Start")
}
func clientDidStop(_ client: SINClient!) {
//print("Stop")
}
func clientDidFail(_ client: SINClient!, error: Error!) {
print(error.localizedDescription)
print(error)
print("Fail")
}
And in the needed ViewController
func getSinchClient() -> SINClient {
let mainDelegate = UIApplication.shared.delegate as! AppDelegate
return mainDelegate.sinchObject!
}
func call(){
if (getSinchClient().isStarted()){
sinchCall = getSinchClient().call()?.callUserVideo(withId: callerId)
sinchCall!.delegate = self
}
}
func callDidProgress(_ call: SINCall!) {
print("Call Progress")
}
func callDidEnd(_ call: SINCall!) {
print("Call End")
print(call.details.endCause.rawValue)
}
func callDidAddVideoTrack(_ call: SINCall!) {
print("Call Got Video")
}
func callDidEstablish(_ call: SINCall!) {
print("Call Connected")
}
I'm trying to write a simple command line app that can display some info on a notification. But, the Delegate is not being called, and neither is the Notification and I'm not sure what's missing here.
Judging from my output, I think the whole problem stems from the AppDelegate not being instantiated. But I am creating one just before I show call showNotification.
What am I missing here?

I have Parse class called Product that has 238 rows. Note that this class is not the Parse.com implementation of Product, it is a custom class implemented by myself, as I didn't require all the columns Parse adds to their Product class.
The Product class has a Pointer column (basically a foreign key in SQL tables), called ShopId, because each product belongs to a specific Shop (I have a Parse class called Shop with an ObjectId column used in the Product Pointer.
My Product class also has a File column called imageFile that holds the image of the product.
I want to download all Products from a specific shop, unpackage their image file and put it in my Swift Product class which consists of the PFObject of the Parse Product, and a UIImageView and a UIImage. Here is my Product Class in Swift:
class Product {
private var object: PFObject
private var imageView: MMImageView!
private var image: UIImage
init(object: PFObject, image: UIImage) {
self.object = object
self.image = image
}
func getName() -> String {
if let name = object["name"] as? String {
return name
} else {
return "default"
}
}
func setImageView(size: CGFloat, target: DressingRoomViewController) {
self.imageView = MMImageView(frame:CGRectMake(0, 0, size, size))
imageView.contentMode = UIViewContentMode.ScaleAspectFit
imageView.image = self.image
imageView.setName(object["category"] as! String)
imageView.backgroundColor = UIColor.clearColor()
imageView.userInteractionEnabled = true
let tapGestureRecognizer =
UITapGestureRecognizer(target: target, action: "imageTapped:")
tapGestureRecognizer.numberOfTapsRequired = 1
imageView.addGestureRecognizer(tapGestureRecognizer)
}
func getImageView() -> MMImageView {
return self.imageView
}
}
I am currently downloading all the products just fine, and getting their image file and creating my Swift Products with their images. However my UIProgressView logic is slightly off. I have the UIProgressView running for every product, every time I unpackage the product image. I need to shift the Parse.com ProgressBlock out of the getProduct swift function and into the loadProducts #IBAction. When I try it, it causes a lot of errors before compilation. How do I shift the ProgressBlock up to the loadProducts #IBAction? Here is my current code:

shopQuery.getObjectInBackgroundWithId("QjSbyC6k5C") {
(glamour: PFObject?, error: NSError?) -> Void in
if error == nil && glamour != nil {
let query = PFQuery(className:"Product")
query.whereKey("shopId", equalTo: glamour!)
query.findObjectsInBackgroundWithBlock {
(objects: [AnyObject]?, error: NSError?) -> Void in
self.getAllProductsAndCategories(objects, error: error)
}

}
}

var alreadyThere: Bool = false
for item in self.categories {

break
}
}

}

self.progressView?.progress = Float(percentDone)
if (percentDone == 100) {
//self.performSegueWithIdentifier("dressingRoom", sender: UIColor.greenColor())
}
})
}
}
}
I decided to not use the progressBlock, and instead to update my UIProgressView manually with a calculation. So here is the code. It's a little rusty. I could refactor now and maybe implement a calculated variable to make it cleaner. If my solution is a bad practice then I'm appreciative if that gets pointed out, and a better solution suggested (It doesn't seem good for performance to check the UIProgressView.progress value every iteration to perform the completion task of performing the segue).

I found this on the Parse website. It may be useful as it has a block that shows the percentage done that updates regularly during the download!
let str = "Working at Parse is great!"
let data = str.dataUsingEncoding(NSUTF8StringEncoding)
let file = PFFile(name:"resume.txt", data:data)
file.saveInBackgroundWithBlock({
(succeeded: Bool, error: NSError?) -> Void in
// Handle success or failure here ...
}, progressBlock: {(percentDone: Int32) -> Void in
// Update your progress spinner here. percentDone will be between 0 and 100.
})
Did you find a better solution? besides this? I am trying to do something similar.
Does any body else have the problem were they can't see the banner for iAds but when you first run the app a big blue screen shows up and says your now connected to iAds. I'm running my app an my iPhone and my iAD developer app testing fill rate is set to 100%

I am setting up an iOS 8 app to request Heath Kit Store authorization to share types. The request Read/Write screen shows fine and on selecting Done, I see the completion callback immediately after. In this callback, I am pushing a new view controller. I set a breakpoint for the code that is programmatically pushing the next view controller and this is called immediately, but the transition doesn't occur until about 10 seconds later.
Some code:
#IBAction func enable(sender: AnyObject) {
let hkManager = HealthKitManager()
hkManager.setupHealthStoreIfPossible { (success, error) -> Void in
if let error = error {
println("error = \(error)")
} else {
println("enable HK success = \(success)")
self.nextStep()
}
}
}
func nextStep() {
self.nav!.pushViewController(nextController, animated: true)
}
class HealthKitManager: NSObject {
let healthStore: HKHealthStore!
override init() {
super.init()
healthStore = HKHealthStore()
}
class func isHealthKitAvailable() -> Bool {
return HKHealthStore.isHealthDataAvailable()
}
func setupHealthStoreIfPossible(completion: ((Bool, NSError!) -> Void)!) {
if HealthKitManager.isHealthKitAvailable()
{
healthStore.requestAuthorizationToShareTypes(dataTypesToWrite(), readTypes: dataTypesToRead(), completion: { (success, error) -> Void in
completion(success, error)
})
}
}
func dataTypesToWrite() -> NSSet {
let runningType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierDistanceWalkingRunning)
let stepType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierStepCount)
return NSSet(objects: runningType, stepType)
}
func dataTypesToRead() -> NSSet {
let runningType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierDistanceWalkingRunning)
let stepType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierStepCount)
let climbedType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierFlightsClimbed)
return NSSet(objects: runningType, stepType, climbedType)
}
}
Any thoughts on what is causing the time delay for the transition?
The problem was that the completion block is returned in the background queue. I just put the transition call back onto the main queue as follows:
hkManager.setupHealthStoreIfPossible { (success, error) -> Void in
if let error = error {
println("error = \(error)")
} else {
dispatch_async(dispatch_get_main_queue(), {
println("enable HK success = \(success)")
self.nextStep()
});
}
}
}
