获取IAP产品响应后的Objective-C错误 [英] Objective-C errors after getting the IAP product response

问题描述

此代码来自Phonegap代码：IAP插件。错误发生在发送js之后的代码行。发送到函数的所有元素都是非零，除了最后一个nil。我甚至登出他们，以确保他们发送。此代码即将使用此插件（ https://github.com/usmart/InAppPurchaseManager-EXAMPLE）并且除了日志记录之外没有被修改。在调试器中我看到没有对象是nil，所以我不明白为什么错误正在发生。

This code is from the Phonegap Code: IAP Plugin. The error happens on the line of the code right after the "sent js". All the elements sent to the function are non-nil except for the last one 'nil'. I even logged them out to make sure they were sent. This code is right out of the plugin (https://github.com/usmart/InAppPurchaseManager-EXAMPLE) and has not been modified except for the logging. In the debugger i saw that none of the objects were nil, so i don't understand why the error is happening.

这里是错误：

[__ NSArrayI JSONRepresentation]：无法识别的选择器发送到

这里是代码：

      - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:   (SKProductsResponse *)response
      {
        NSLog(@"got iap product response");
        for (SKProduct *product in response.products) {
            NSLog(@"sending js for %@", product.productIdentifier);
            NSLog(@"  title %@", product.localizedTitle );
            NSLog(@"  desc%@ - %@", product.localizedDescription, product.localizedPrice );


NSArray *callbackArgs = [NSArray arrayWithObjects:
                                 NILABLE(product.productIdentifier),
                                 NILABLE(product.localizedTitle),
                                 NILABLE(product.localizedDescription),
                                 NILABLE(product.localizedPrice),
                                 nil ];
        NSLog(@"sent js");

        NSString *js = [NSString stringWithFormat:@"%@.apply(plugins.inAppPurchaseManager, %@)", successCallback, [callbackArgs JSONSerialize]];
        NSLog(@"js: %@", js);
        [command writeJavascript: js];
    }

推荐答案

JSONRepresentation 是 SBJson 添加的类别，因此您必须将 SBJson.h 使用它的类。

JSONRepresentation is a category that SBJson adds so you have to include SBJson.h in the class that uses it.
