Question

我在app中购买了代码并将其返回给我：

这是我的代码：

#import "PurchaseViewController.h"
@interface PurchaseViewController ()
@property (strong, nonatomic) SKProduct *product;
@property (strong, nonatomic) PurchaseViewController *purchaseController;
@property (strong, nonatomic) NSString *productID;

- (void)getProductInfo:(UIViewController *)viewController;
@end
@implementation PurchaseViewController
- (void)viewDidLoad {
  [super viewDidLoad];
_purchaseController = [[PurchaseViewController alloc]init];
[[SKPaymentQueue defaultQueue] addTransactionObserver:_purchaseController];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
}
- (IBAction)purchaseItem:(id)sender {
_purchaseController.productID = @"game";

[self.navigationController
 pushViewController:_purchaseController animated:YES];
[_purchaseController getProductInfo: self];
SKPayment *payment = [SKPayment paymentWithProduct:_product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
-(void)getProductInfo: (PurchaseViewController *) viewController
{
if ([SKPaymentQueue canMakePayments])
{
    SKProductsRequest *request = [[SKProductsRequest alloc]
                                  initWithProductIdentifiers:
                                  [NSSet setWithObject:self.productID]];
    request.delegate = self;
    [request start];
}
else
    _productDescription.text =
    @"Please enable In App Purchase in Settings";
     }
#pragma mark -
#pragma mark SKProductsRequestDelegate
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{

NSArray *products = response.products;
products = response.invalidProductIdentifiers;
_product = products[0];
for (SKProduct *product in products)
{
    NSLog(@"Product not found: %@", product);
}
}
#pragma mark -
#pragma mark SKPaymentTransactionObserver
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
    switch (transaction.transactionState) {
        case SKPaymentTransactionStatePurchased:
            [self unlockFeature];
            [[SKPaymentQueue defaultQueue]
             finishTransaction:transaction];
            break;
        case SKPaymentTransactionStateFailed:
            NSLog(@"Transaction Failed");
            [[SKPaymentQueue defaultQueue]
             finishTransaction:transaction];
            break;     
        default:
            break;
    }
}
}
-(void)unlockFeature
{
    NSLog(@"bought");
}
@end

错误表示正在向字符串发送productIdentifier getter消息。如果你自己没有这样做，可能是SKPaymentQueue试图访问...的产品标识符......也许是SKProduct？但是，它不是SKProduct（或响应productIdentifier的类似StoreKit对象），而是对字符串的引用。

查看你的代码（而不知道崩溃发生在哪里）我猜你的_product实际上是设置为NSString而不是SKProduct。要测试这一点，请断开purchaseItem中的代码：在paymentWithProduct：之前，并在调试器中键入po [_product class]。它实际上是SKProduct吗？
