c++ - Cocos2dx InApp Purchase for ios

Question

我正在尝试将 In App Purchases 集成到我使用 cocos2d x c++ 制作的应用程序中。我正在使用 easyNdk Helper 进行应用内购买。我的应用内购买非常适合我的 Objective C 应用。但是对于 cocos2d x 它会为以下行抛出错误

if ([[RageIAPHelper sharedInstance] productPurchased:productP.productIdentifier])

实际上，值以参数的形式完美地来自 CPP 文件，并在 NSLog 中正确显示它们的值，但它始终将对象显示为 nil，甚至对象在 NSLog 中打印它们的存储值

@try catch 条件也不起作用

最后抛出如下错误

请帮助我我必须做什么？ 谢谢

我的.CPP代码是

 NDKHelper::AddSelector("HelloWorldSelectors",
                           "SampleSelector",
                           callfuncND_selector(Main::cameFromObjC),
                           this);

            CCDictionary* prms = CCDictionary::create();
            prms->setObject(CCString::create("SampleSelector"), "to_be_called");
            prms->setObject(CCString::create(result), "BirdNameKey");
SendMessageWithParams(string("SampleSelector"), prms);

.mm代码是

- (void) SampleSelector:(NSObject *)prms
{
    NSLog(@"purchase something called");
    NSDictionary *parameters =   [[NSDictionary alloc]init];// (NSDictionary*)prms;
    parameters = (NSDictionary*)prms;
    NSLog(@"Passed params are : %@", parameters);

    // Fetching the name of the method to be called from Native to C++
    // For a ease of use, i have passed the name of method from C++
    NSString* CPPFunctionToBeCalled = (NSString*)[parameters objectForKey:@"to_be_called"];
    //NSString *str = [NSString stringWithFormat:@"%@",[parameters valueForKey:@"BirdNameKey"]];
    NSString *BirdName =  [parameters valueForKey:@"BirdNameKey"];
    NSString *str = [[NSString alloc]initWithFormat:@"%@",[parameters objectForKey:@"BirdNameKey"]];
    NSUserDefaults *d2 = [NSUserDefaults standardUserDefaults];
    NSLog(@"%@ , %@ , %@", str,BirdName,[d2 objectForKey:@"product"]); // output is ok for all
    SKProduct * product = (SKProduct *) [ APPDELEGATE.productDictionary objectForKey:[d2 objectForKey:@"product"]];
    [ APPDELEGATE.priceFormatter setLocale:product.priceLocale];
    APPDELEGATE.currentProduct =product;

if ([[RageIAPHelper sharedInstance] productPurchased:product.productIdentifier])
        {
           // check the product purchased or not but app crash at this if statement
        }
   [IOSNDKHelper SendMessage:CPPFunctionToBeCalled WithParameters:nil];
}

我也遇到过这个问题，我已经解决了。 在你的 IAPhelper.mm 中

只做这个替换这一行

_purchasedProductIdentifiers = [NSMutableSet set];

下面一行

_purchasedProductIdentifiers = [[NSMutableSet alloc] init];

如下图

 - (id)initWithProductIdentifiers:(NSSet *)productIdentifiers {

    if ((self = [super init])) {

        // Store product identifiers
        _productIdentifiers = productIdentifiers;

        // Check for previously purchased products
//        _purchasedProductIdentifiers = [NSMutableSet set];
        _purchasedProductIdentifiers = [[NSMutableSet alloc] init];
        for (NSString * productIdentifier in _productIdentifiers) {
            BOOL productPurchased = [[NSUserDefaults standardUserDefaults] boolForKey:productIdentifier];
            if (productPurchased) {
                [_purchasedProductIdentifiers addObject:productIdentifier];
                // NSLog(@"Previously purchased: %@", productIdentifier);
            } else {
                // NSLog(@"Not purchased: %@", productIdentifier);
            }
        }

        // Add self as transaction observer
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

    }
    return self;

}
