iOS Google Tag Manager Purchase 事件为数量参数发送 0(零)

Question

注:已在帖子中提出:Quantities of items are not tracked in google analytics transactions但没有回答。

当使用适用于 iOS (Objective-C) 的 Google 跟踪代码管理器([编辑] 版本 3.06)并发送购买事件时，如 the example 中所述事件被发送，我可以在 Google Analytics 后端读回它，但是数量的值始终为 0(零)。价格也是 0(零)，但我不确定这是否是由于数量为 0 造成的。其他所有参数似乎都发送得很好。

请注意，我实现了 android SDK 没有任何问题。

现在的代码是(为了便于阅读而改变):

int quantity = 1;
float price = 0.89f;
float shipping = 0.0f;
float tax = 0.0f;

TAGDataLayer *dataLayer = [TAGManager instance].dataLayer;

NSMutableArray *purchasedItems = [NSMutableArray array];

[purchasedItems addObject:@{@"name": GetStringParam(name),
                            @"sku": GetStringParam(SKU),
                            @"category": GetStringParam(category),
                            @"price": [NSNumber numberWithFloat:price],
                            @"currency": @"EUR",
                            @"quantity": [NSNumber numberWithInt:quantity]
                            }];

[dataLayer push:@{@"event": @"Transaction",
                  @"transactionId": GetStringParam(transactionID),
                  @"transactionTotal": [NSNumber numberWithInt:quantity],
                  @"transactionAffiliation": GetStringParam(affiliation),
                  @"transactionTax": [NSNumber numberWithFloat:tax],
                  @"transactionShipping": [NSNumber numberWithFloat:shipping],
                  @"transactionCurrency": @"EUR",
                  @"transactionProducts": purchasedItems
                  }];

[dataLayer push:@{@"transactionId": [NSNull null],
                  @"transactionTotal": [NSNull null],
                  @"transactionAffiliation": [NSNull null],
                  @"transactionTax": [NSNull null],
                  @"transactionShipping": [NSNull null],
                  @"transactionCurrency": [NSNull null],
                  @"transactionProducts": [NSNull null]
                  }];

我是做错了什么还是 GTM SDK for iOS 的已知问题？我真的很想在这方面得到一些帮助。

更新:只是想添加 GTM 生成的日志:

Saved hit: {
parameters =     {
    "&_u" = ".L";
    "&_v" = "mi3.0.6";
    "&aid" = "[this is confidential]";
    "&an" = "[this is confidential]";
    "&av" = "[this is confidential]";
    "&cd" = "/Home";
    "&cid" = "60dc5171-1a8d-40ed-9f90-cc2cb1bbb30d";
    "&cu" = EUR;
    "&ic" = "Test-SKU";
    "&in" = "Test-name";
    "&ip" = "0.89";
    "&iq" = 1;
    "&iv" = "Test-category";
    "&sr" = 320x480;
    "&t" = item;
    "&ti" = "TEST-PURCHASE_JXJKY0N8";
    "&tid" = "UA-XXXXXX-2";
    "&ul" = en;
    "&v" = 1;
    "&z" = 12665685598291294076;
    gaiVersion = "3.06";
};
timestamp = "2014-04-10 11:02:23 +0000";
}

如果需要任何其他信息，请告诉我。

干杯，尼尔斯

当前(3.06 版)的 iOS SDK 中存在一个错误，您不应在推送的电子商务事件中提供 NSNumbers 作为值。解决方法是改用字符串(例如，[NSString stringWithFormat @"%1.2f", price])。

我们正在努力修复错误。
