Swift In App Purchases - ios

Hopefully this is enough information to help me solve my problem.
I am setting up In App Purchases via a templated source code that was given to me. In my MKStoreManager.m file, where I set up the featureID's for my in app purchases (Ex: static NSString *featureAId = #"com.logannat.myfirstgameTier1";)
When clicking on the actual button in the game, a method
- (void) buyFeature:(SKProduct*) product
{
if ([SKPaymentQueue canMakePayments])
{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
}
ends up getting called. I set a break point, and found the error to be in the last line of that code.
The variables that show up in the break point state are:
self = (MKStoreManager *)"reference number"
product = (SKProduct *) nil
and
payment = (SKPayment *) "reference number"
I can not seem to figure out what the problem is here. Any help would be much appreciated, thank you.

i do not have swift Right now so i am giving you Xcode code please convert the syntax accordingly its not so difficult.
so here is the complete life cycle for the in app purchased.
in your header file call these delegates and setup the bool for checking the status of you purchased
like that
#import <UIKit/UIKit.h>
BOOL arefavorite_access;
BOOL areAdsRemoved;
#interface ViewController : UIViewController<SKProductsRequestDelegate, SKPaymentTransactionObserver>{
}
- (IBAction)purchase;
- (IBAction)restore;
- (IBAction)tapsRemoveAds:(id)sender;
#end
one you need to hockup this tapsRemoveAds method on touchupinside of you button selector ant it will start working.
- (IBAction)tapsRemoveAds:(id)sender{
UIButton*btn=(UIButton*)sender;
NSString *featureAId = #"com.logannat.myfirstgameTier1";
NSLog(#"User requests to remove ads");
if([SKPaymentQueue canMakePayments]){
NSLog(#"User can make payments");
SKProductsRequest *productsRequest;
if (btn.tag==1) {
productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject: featureAId]];
_protype= featureAId;
}
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(#"User cannot make payments due to parental controls");
//this is called the user cannot make payments, most likely due to parental controls
}
}
product request method
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
validProduct = [response.products objectAtIndex:0];
NSLog(#"Products Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(#"No products available");
//this is called if your product id is not valid, this shouldn't be called unless that happens.
}
}
- (IBAction)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (IBAction) restore{
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
NSLog(#"%#",queue );
NSLog(#"Restored Transactions are once again in Queue for purchasing %#",[queue transactions]);
NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];
NSLog(#"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions) {
NSString *productID = transaction.payment.productIdentifier;
[purchasedItemIDs addObject:productID];
NSLog (#"product id is %#" , productID);
_protype=productID;
[self doRemoveAds];
// here put an if/then statement to write files based on previously purchased items
// example if ([productID isEqualToString: #"youruniqueproductidentifier]){write files} else { nslog sorry}
}
if(queue.transactions.count==0){
[Utilities showOKAlertWithTitle:#"Restore purchase" message:#"you have no product available for restoration"];
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
switch(transaction.transactionState){
case SKPaymentTransactionStatePurchasing: NSLog(#"Transaction state -> Purchasing");
//called when the user is in the process of purchasing, do not add any of your own code here.
break;
case SKPaymentTransactionStatePurchased:
//this is called when the user has successfully purchased the package (Cha-Ching!)
[self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(#"Transaction state -> Purchased");
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
case SKPaymentTransactionStateRestored:
NSLog(#"Transaction state -> Restored");
_protype=transaction.payment.productIdentifier;
[self doRemoveAds];
//add the same code as you did from SKPaymentTransactionStatePurchased here
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
case SKPaymentTransactionStateFailed:
//called when the transaction does not finish
if(transaction.error.code == SKErrorPaymentCancelled){
NSLog(#"Transaction state -> Cancelled");
//the user cancelled the payment ;(
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
}
}
}
- (void)doRemoveAds{
// // [self.bannerView setAlpha:0];
NSString *featureAId = #"com.logannat.myfirstgameTier1";
NSString *featureAIdnumber2 = #"com.logannat.myfirstgameTier2";
if([_protype isEqualToString:featureAId]){
arefavorite_access = YES;
[[NSUserDefaults standardUserDefaults] setBool:arefavorite_access forKey:frareFavoriteRemoved];
[[NSUserDefaults standardUserDefaults] synchronize];
}
else if([_protype isEqualToString: featureAIdnumber2]){
areAdsRemoved = YES;
[[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:frareAdsRemoved];
[[NSUserDefaults standardUserDefaults] synchronize];
}
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
// [self showpopUp:self];

Various Glitches With In App Purchase (iOS)

I've been experiencing various glitches with in-app purchases. Here are a few.
When I tap an item to buy it, it shows the Confirm you In-App Purchase alert and then after a second or so, it closes it self and opens the login alert.
Some times I'll log in, then it will ask me to log in again. Alerts pop up and go away on their own and it looks very glitchy. Some times the app crashes with no error message.
I haven't been able to search for any answers because these issues are quite strange.
Here is the code I'm using (I'm using a class named Game and a category names Game-Resources)
Game.m:
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
product = response;
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
if (purchasing == NO){
// if I don't put (purchasing) in, this method is run multiples times
purchasing = YES;
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
for (SKPaymentTransaction * transaction in transactions){
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:
NSLog(#"purchasing");
break;
case SKPaymentTransactionStatePurchased:
purchasing = NO;
NSLog(#"done");
if ([[NSUserDefaults standardUserDefaults] objectForKey:purchaseNSUserName] != nil){
int i = (int) [[NSUserDefaults standardUserDefaults] integerForKey:purchaseNSUserName];
[[NSUserDefaults standardUserDefaults] setInteger:i + purchaseNSUserAmount forKey:purchaseNSUserName];
[[NSUserDefaults standardUserDefaults] synchronize];
}else{
[[NSUserDefaults standardUserDefaults] setInteger:purchaseNSUserAmount forKey:purchaseNSUserName];
[[NSUserDefaults standardUserDefaults] synchronize];
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
purchasing = NO;
break;
case SKPaymentTransactionStateFailed:
purchasing = NO;
if (transaction.error.code != SKErrorPaymentCancelled){
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
//error happened
}
break;
case SKPaymentTransactionStateDeferred:
purchasing = NO;
break;
default:
break;
}
purchaseNSUserName = nil;
purchaseNSUserAmount = 0;
}
}
}
In the ViewDidLoad:
if ([SKPaymentQueue canMakePayments]){
self.productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObjects:#"somethinghere", #"anotherthing", nil]];
self.productsRequest.delegate = self;
[self.productsRequest start];
}
In Game-Resources (when buy button is pressed):
SKPayment *payment = [SKPayment paymentWithProduct: product.products[productID]];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];

Adding more in-app purchases

I followed this tutorial to help me add in-app purchases. It works well, except now I am trying to add another non-consumable IAP. I defined my second product ID and created a method for the purchase button, but I'm not sure if I have to create another SKProductsRequest for this extra item, or if I use the same one, etc...
Here is my full code.
#define kRemoveAdsProductIdentifier #"099"
#define kDoubleEarningRateProductIdentifer #"199"
- (void)removeAds{
NSLog(#"User requests to remove ads");
if([SKPaymentQueue canMakePayments]){
NSLog(#"User can make payments");
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(#"User cannot make payments due to parental controls");
//this is called the user cannot make payments, most likely due to parental controls
}
}
- (void)doubleEarningRate{
NSLog(#"User requests 2x earning rate");
if([SKPaymentQueue canMakePayments]){
NSLog(#"User can make payments");
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kDoubleEarningRateProductIdentifer]];
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(#"User cannot make payments due to parental controls");
//this is called the user cannot make payments, most likely due to parental controls
}
}
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
validProduct = [response.products objectAtIndex:0];
NSLog(#"Products Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(#"No products available");
//this is called if your product id is not valid, this shouldn't be called unless that happens.
}
}
- (void)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (void) restore{
//this is called when the user restores purchases, you should hook this up to a button
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
NSLog(#"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions)
{
if(SKPaymentTransactionStateRestored){
NSLog(#"Transaction state -> Restored");
//called when the user successfully restores a purchase
[self doRemoveAds];
[self doubleEarningRate];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
switch (transaction.transactionState){
case SKPaymentTransactionStatePurchasing: NSLog(#"Transaction state -> Purchasing");
//called when the user is in the process of purchasing, do not add any of your own code here.
break;
case SKPaymentTransactionStatePurchased:
//this is called when the user has successfully purchased the package (Cha-Ching!)
[self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(#"Transaction state -> Purchased");
break;
case SKPaymentTransactionStateRestored:
NSLog(#"Transaction state -> Restored");
//add the same code as you did from SKPaymentTransactionStatePurchased here
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
//called when the transaction does not finnish
if(transaction.error.code != SKErrorPaymentCancelled){
NSLog(#"Transaction state -> Cancelled");
//the user cancelled the payment ;(
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
}
}
}
-(void)doRemoveAds
{
areAdsRemoved = true;
NSLog(#"Ads Removed");
[topBanner removeFromSuperview];
}
-(void)doDoubleEarningRate
{
}
I also read through apple documentation which explained to me what each part does, but I am still clueless on how I can add another purchase, and most other tutorials are done differently or outdated. Also all the variables and indirection is a bit intimidating to me. So I am hoping that someone can give me a quick step by step guide for adding another purchase.
To make it clearer, this approach works perfectly for just one in app purchase. However I don't know how to add more, as in I don't know how to make the program recognize which in-app purchase is being selected.
Thanks.
I fixed this by creating a method called provideContent:(NSString *)productId. Then you can either use a switch statement or if statement to differentiate between product Id's. No need to create multiple types of productRequest methods, etc...

Error with adding in-app purchases - Cocos2d

I used info from this brilliant page to add in-app purchases.
However I get the NSLog No Product Available. I have checked to make sure I have added the correct Product ID. I am at a loss to what to do and have been at this for several hours.
This is for a game built on Cocos2d and I can't figure out what is wrong. Sorry for the abundance of code.

If it's a debug build you probably need to add a sandbox user on iTunes connect this will allow you to use IAP that have not been reviewed yet. Note this user should match your iTunes connect account.

Trouble implementing in app purchase

I have been following this tutorial on implementing an in app purchase - How do you add an in-app purchase to an iOS application?
However I get errors on lines:
productsRequest.delegate = self;

Those are not errors but warnings, you should add protocol conformance to your class declaration.

Following in app purchase, app crashing on startup. productIdentifier=nil?

I have a few users who have reported that after attempting an in app purchase the app is now crashing on startup. I have asked them to delete and reinstall the app which has not worked, and attempted to ask them to go into airplane mode to stop any network communication that has not worked.
I am unable to replicate the error in anyway on my devices and my in app purchase goes through just fine in sandbox and production modes. My thought is that somehow their transaction received a nil productIdentifier which is causing the startup crash but I am not sure what transaction observer methods get called at app startup that I can fix the issue for them.
Is there someway to "clear" the transaction queue or otherwise test for nil productidentifiers on start up and allow these users to get the app at least running again? I've done several hundred in app purchases using the code below and this just recently began happening. Which of the helper methods get called on app startup?
In AppDelegate.m
[[SKPaymentQueue defaultQueue] addTransactionObserver:[MovieClockIAPHelper sharedHelper]];
In app helper code:
- (id)initWithProductIdentifiers:(NSSet *)productIdentifiers {
if ((self = [super init])) {
// Store product identifiers
_productIdentifiers = [productIdentifiers retain];
// Check for previously purchased products
NSMutableSet * purchasedProducts = [NSMutableSet set];
for (NSString * productIdentifier in _productIdentifiers) {
BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier];
if (productPurchased) {
[purchasedProducts addObject:productIdentifier];
NSLog(#"Previously purchased: %#", productIdentifier);

I've run into a similar issue when the transaction is in the SKPaymentTransactionStateRestored. My testing has indicated this might be an issue with IOS 7.0.3, but I have not been able to verify this.
StoreKit keeps a persistent list of transactions that your application must finish. As you've noted the transaction will be reported on every startup until it is finished.
The solution that we implemented is to check if the product identifier is nil before usage from the entry point:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
Even when we received a transaction with a nil product identifier we were able to successfully call finishTransaction.
I hope this helps.
One of my users complained four days ago about the same problem and was able to send me a crash log. He uses iOS 7.0.3 on iPhone 5,2. Crash occurs after identifying a SKPaymentTransactionStateRestored while trying to build a dictionary with the productIdentifier property from originalTransaction.payment:
NSDictionary* userInfoDict = #{#"productID":transaction.payment.productIdentifier};
I think that either originalTransaction or its properties payment or productIdentifier is nil. I stored the productIdentifier from transaction.payment.productIdentifier instead from transaction.originalTransaction.payment.productIdentifier while restoring and use that as productIdentifier from then on:
case SKPaymentTransactionStateRestored:
{
NSString *productID = transaction.originalTransaction.payment.productIdentifier;
if (!productID) {
productID = transaction.payment.productIdentifier;
}
[self handlePurchaseSuccessful:transaction.originalTransaction productIdentifier:productID];
}
Still waiting for review / feedback if that fixes the issue.
Elaborating on Shawn's answer, in - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions you probably have some code like this:
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
for (SKPaymentTransaction *transaction in transactions)
{
switch (transaction.transactionState)
{
case SKPaymentTransactionStatePurchased:
[self completeTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
[self restoreTransaction:transaction];
default:
break;
}
}
}
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
/* Handle restore here */
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
You can handle nil productIdentifiers in restoreTransaction: by adding a check to see if the productIdentifier is nil, like this:
- (void) restoreTransaction: (SKPaymentTransaction *)transaction
{
if (!transaction.originalTransaction.payment.productIdentifier) {
NSLog(#"productIdentifier is nil; Apple bug?");
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
return;
}
/* Handle restore here */
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
This technique fixed the problem for me in my app. The app started, logged "productIdentifier is nil; Apple bug?" and didn't crash. When I then manually re-restored transactions, Apple sent a valid transaction, and the app worked as designed.
I fixed this issue as Marimba posted above and it helped for our customers:
case SKPaymentTransactionStateRestored:
{
NSString *productID = transaction.originalTransaction.payment.productIdentifier;
if (productID == nil) {
productID = transaction.payment.productIdentifier;
}
[self handlePurchaseSuccessful:transaction.originalTransaction productIdentifier:productID];
}
I had the same problem paymentQueue:updatedTransactions: was being called with SKPaymentTransaction instances with a state of SKPaymentTransactionStateRestored and a nil productIdentifier in the originalTransaction.
It sounds really weird and might be a 7.0.3 SDK bug.
Do you all still compile with the SDK 6 ?
I'm about to resubmit my app to the store to see if the issue gets fixed but just finishing such transactions but I hope other transactions with a valid productIdentifier are going to be processed now that the app won't crash so that I know what to restore.
