Question

当我运行我的下面的代码时，它会在我的设备上给出这个响应....

- (void) requestProductData
{
 //
 NSString *str = [[NSString alloc] initWithFormat:@"com.mycompany.inapppurchasetesting.productid"];//Same as the Product Id displayed in Itunes Connect//"]; 

 SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:str]]; 

 request.delegate = self;

 [request start];
 //
 //NSSet *productIDs = [NSSet setWithObjects:@"com.mycompany.inapppurchasetesting.productid", nil];

 //SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:productIDs];

 //request.delegate = self;

 NSLog(@"Requesting");

 //[request start];
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
    NSArray *myProduct = response.products;

 NSArray *myInvalidProducts = response.invalidProductIdentifiers;

 NSLog(@"Did recieve response");

    NSLog(@"Response count is %d",response.products.count);
 NSLog(@"Invalid response count is %d",response.invalidProductIdentifiers.count);

 for (int i = 0; i<myProduct.count; i++)
 {
  NSLog(@"t:%@",[[myProduct objectAtIndex:i] localizedTitle]);
 }

 for(int i = 0; i < myInvalidProducts.count; ++i)
 {
  NSLog(@"Invalid products:%@",[[myInvalidProducts objectAtIndex:i] localizedTitle]);
    }

 // populate UI
 [request autorelease];
}

为什么会出现上述错误......

请指导我......

Answer 1

因为invalidProductIdentifiers只包含NSString s的数组，而不是SKProduct s。

See the StoreKit documentation.

NSLog(@"Invalid products:%@",[myInvalidProducts objectAtIndex:i]);

Answer 2

你是不是想在NSCFString上调用“localizedTitle”而不是产品？
