iOS In-App Purchase, Problems & Solutions

[ArtOfWarfare]

Edit #4: Error 0 Solved

I created a new test user with an email address I knew. I signed out of the store in the Settings app, then opened my app (no new install of it needed) and attempted to purchase with the new account. It said I needed to verify the account, so I did, and I went back and tried again, and it worked!

So, hopefully this thread can help someone with any of the numerous IAP issues I had.

(Resolved) Edit #3: Getting error 0?

This is the article that made me think threading might have anything to do with getting error 0:
http://blog.mugunthkumar.com/coding...annot-connect-to-itunes-store-skerrorunknown/

So I decided to replace:

[[SKPaymentQueue defaultQueue] addPayment:[SKPayment paymentWithProductIdentifier:@"quickClipsAdRemoval"]];

with:

[[SKPaymentQueue defaultQueue] performSelectorOnMainThread:(@selector(addPayment:)) withObject:[SKPayment paymentWithProductIdentifier:@"quickClipsAdRemoval"] waitUntilDone:NO];

but it appears to have resolved nothing. I still receive an error code of 0.

I could really use some help...

(Resolved) Edit #2: Fixed 5002

I resolved 5002 by deleting the app from my iPhone, then logging out from the store in settings, then installing my app on my iPhone again, and then logging in when it prompted me to in my app. Somehow it wasn't going to the sandbox environment before. And now I'm receiving error 0, which something has told me is possibly because my call to add my product to the queue isn't occurring on the main thread.

(Resolved) Edit #1: Fixed Crash

I looked through the crash log and noticed that finishTransaction: was getting called. Seemed odd, given that the Store Kit never gave me a confirmation page. I looked into my code a bit and found that in my effort to reduce how many lines I use, I moved finishTransaction: outside of the switch statement for my transaction observer. I checked the method for finishedTransaction:, and found that evidently invoking finishedTransaction: on a transaction in the middle of purchasing will cause the application to crash. So, yeah, that's the cause of the crash. I fixed that. Now I have an error 5002.

(Resolved) Original: Getting a Crash...

Okay, so this whole thing was weird.

I made an IAP for version 1.0 of my app, but forgot to attach the IAP when I uploaded the app to Apple, so it didn't ever get reviewed.

Then in 1.1, I remembered to include it for review. The app as a whole was rejected, but my IAP remained "In-Review".

Before releasing 1.2, I wanted to test my IAP, but I couldn't, because it was stuck "In-Review". When I tested my app, I always ended up with the issue that

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response

the response was always an empty array while testing, I figured because of the limbo my IAP was stuck in. The empty array caused my app to display an error message, and I decided all I could do was hope that it would work when 1.2 was released, and if it didn't, at least it would have the grace to explain that it failed.

Well, 1.2 has now been released, and when users are going to get the IAP, the app doesn't throw up an error, instead, it just crashes.

Here's all the code:

In my header, I've got these:

#import <StoreKit/StoreKit.h> //The framework is included in my project.
#import "Reachability.h"

@interface HelpMenu : UIViewController <... UIAlertViewDelegate, SKProductsRequestDelegate, SKPaymentTransactionObserver>
{
    IBOutlet    UIBarButtonItem         *purchaseButton;
    IBOutlet    UIActivityIndicatorView *purchaseIndicator;
    int                                 responseStatus;
}

- (IBAction)purchase;

In main, the related portions are:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

        {
            NSLog(@"No internet connection.");
        }

Thus far, people have not been getting error popups, but simply crashes when they hit the button.

I was actually looking for help when I posted each thing. It was at the end when I'd finally solved everything myself I decided to retitle the topic. Figured it can help someone (most likely me in the future) from going through the pain of figuring it all out from scratch.
