Google跟踪代码管理器iOS集成–是否向Google Analytics（分析）发送值？

Question

So I'm following Google's atrocious documentation for Google Tag Manager, investigating for my employer whether it's “worth” switching from Google Analytics to using GTM. There's a huge lack of clarity in the documentation of what the difference between the two is, but I've gleaned that GTM in fact seems to just give the marketing team a little more flexibility in the way they collate data on their end.

I'm struggling to understand exactly what benefits GTM has over a simple integration of GA (like we already have).

Secondly, and more technically, following through the examples with a completely fresh Google account, but nothing shows up in the real time view at all, no active users, nothing coming through. I've carbon-copied their example code, like so:

[self.tagManager.dataLayer push:@ {
    @"event"                  : @"openScreen",
    @"screenName"             : screen
}];

Has anyone done this? Do you need to do anything specific with it? Here's what it looks like in GTM, I have no idea if it's right:

Answer 1

The solution for me was to send a variable key called event , and map that on the GTM end to a data layer variable. It didn't seem to know it was an Event until I did that. Completely undocumented on Google's end, so no idea if that's what you're supposed to do.
