【问题描述】：

我正在尝试将一些应用内购买添加到我的 ios 应用中。一切都完成了，但我似乎无法让这些 iap 工作。我从一个教程网站上提取了一些代码，它似乎在那个项目上工作，我不确定我做错了什么。这些 iap 用于游戏中的金币，可以多次使用。

.h

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

@interface IAP : UIViewController <SKProductsRequestDelegate, SKPaymentTransactionObserver, UIAlertViewDelegate>




+(void)myIAPWithItem:(NSString *)Item;

@end

.m

#import "IAP.h"
#import "Money.h"

@interface IAP ()

@end

@implementation IAP;




#define kStoredData @"com.emirbytes.IAPNoobService"




+(void)myIAPWithItem:(NSString *)Item
    if ([SKPaymentQueue canMakePayments]) 
        NSString *PurchaseAddress = [[NSString alloc] initWithString:[NSString stringWithFormat:@"TTE_%@kGold" , Item]];

PurchaseAddress 是 itunesconnect 中这些 iap 的 appid。

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

        request.delegate = self;
        [request start];


     else 
        UIAlertView *tmp = [[UIAlertView alloc]
                            initWithTitle:@"Prohibited"
                            message:@"Parental Control is enabled, cannot make a purchase!"
                            delegate:self
                            cancelButtonTitle:nil
                            otherButtonTitles:@"Ok", nil];
        [tmp show];

    






#pragma mark StoreKit Delegate

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions 
    for (SKPaymentTransaction *transaction in transactions) 
        switch (transaction.transactionState) 
            case SKPaymentTransactionStatePurchasing:

                // show wait view here

                break;
            
            case SKPaymentTransactionStatePurchased:

                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                // remove wait view and unlock feature 2

                UIAlertView *tmp = [[UIAlertView alloc]
                                    initWithTitle:@"Complete"
                                    message:@"You have unlocked Feature 2!"
                                    delegate:self
                                    cancelButtonTitle:nil
                                    otherButtonTitles:@"Ok", nil];
                [tmp show];





                // apply purchase action  - hide lock overlay and
                NSLog(@"It worked!");

                // do other thing to enable the features

                break;
            
            case SKPaymentTransactionStateRestored:
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                // remove wait view here
                                break;
            
            case SKPaymentTransactionStateFailed:

                if (transaction.error.code != SKErrorPaymentCancelled) 
                    NSLog(@"Error payment cancelled");
                
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                // remove wait view here
                               break;
            
            default:
                break;
            
        
    


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


    // remove wait view here


    SKProduct *validProduct = nil;
    int count = [response.products count];

    if (count>0) 
        validProduct = [response.products objectAtIndex:0];

        SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.emirbytes.IAPNoob.01"];
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
        [[SKPaymentQueue defaultQueue] addPayment:payment];


     else 
        UIAlertView *tmp = [[UIAlertView alloc]
                            initWithTitle:@"Not Available"
                            message:@"No products to purchase"
                            delegate:self
                            cancelButtonTitle:nil
                            otherButtonTitles:@"Ok", nil];
        [tmp show];

    




-(void)requestDidFinish:(SKRequest *)request




-(void)request:(SKRequest *)request didFailWithError:(NSError *)error

    NSLog(@"Failed to connect with error: %@", [error localizedDescription]);




#pragma mark AlertView Delegate

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);


@end

所以当我运行它时，什么也没有发生。我可以看到它发送了产品请求，但之后什么也没有。有谁知道我做错了什么？

【参考方案1】：

您是否检查过您的 response.products 计数是否为零？ 你不带产品购买错误吗？ 尝试提供更多信息，也许可以提供更好的帮助。 另外我认为这不是您购买的产品 ID

SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.emirbytes.IAPNoob.01"];

【讨论】：

我解决了这个问题，但我不确定它是什么。今晚晚些时候将发布代码。
