Question

In my iPhone app, i’ve set up an in app purchase. I start the request like this:

SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers: [NSSet setWithObject: @"com.nicknoble.tiprounder.upgrade"]];
request.delegate = self;
[request start];

And I use this method to get the response:

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{   
    NSLog(@"response recieved");
}

And this one to catch an error:

-(void)request:(SKRequest *)request didFailWithError:(NSError *)error
{
    NSLog(@"%@",error.description);
}

But neither ever get called. My project has no warnings or errors, and I am running this on my device (iPhone). Any suggestions?

EDIT:

So it works on my window’s root view controller, but not on modal view controllers i present. Here is the code from my main view controller:

TestViewController *testView = [[TestViewController alloc] initWithNibName:@"TestViewController" bundle:nil];
[self presentModalViewController:testView animated:YES];

Here is the .h file for TestViewController:

#import <UIKit/UIKit.h>
#import <StoreKit/StoreKit.h>

@interface TestViewController : UIViewController <SKProductsRequestDelegate>
@end

Here is the code for my .m file:

#import "TestViewController.h"

@implementation TestViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:     [NSSet setWithObject: @"com.nicknoble.tiprounder.upgrade"]];
    request.delegate = self;
    [request start];
}

-(void)request:(SKRequest *)request didFailWithError:(NSError *)error
{
    NSLog(@"%@",error.description);
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{   
    NSLog(@"response recieved");
}

@end

Im desperate. Any help would be great! Thanks!

Answer 1

check your product identifier first.
also check if the class in which these methods are implemented is not released somehow. (might be autoreleased and got released automatically while you are waiting for response)
