iOS Google 跟踪代码管理器在启动时崩溃 'NSParseErrorException'，原因：'Last tag: 116 should be 124'

Question

我们的其他 3 个 iOS 应用程序中有 Google 带有 Google 标签管理器运行的分析，但由于某些原因，这个最新的应用程序在尝试打开时崩溃容器。

这是有问题的代码行（类似于 GTM's guidelines）：

        NSTimeInterval timeout = 0.1;
        [TAGContainerOpener openContainerWithId:containerName
                                     tagManager:_tagManager
                                       openType:kTAGOpenTypePreferNonDefault
                                        timeout:&timeout
                                       notifier:self];

抛出的错误：

Terminating app due to uncaught exception 'NSParseErrorException', 
reason: 'Last tag: 116 should be 124'

到目前为止，我似乎无法在网上搜索任何信息。到目前为止，我唯一看到的是 GA's Release notes 中提到他们可能已弃用 openContainerWithId，但他们当前的指南对此或使用什么没有任何说明。

感谢任何帮助。

事实证明，如果没有在 Google 标签管理器的服务器端创建实际标签，就会发生此问题。

我们的分析人员最终做了以下事情： 1.在服务器上创建需要的标签 2. 生成我们在代码中更新的新容器文件

然后崩溃消失了，一切正常。
