谷歌标签管理器与 Firebase 崩溃 iOS

Question

我在我的应用程序中使用带有 Firebase 的 Google 跟踪代码管理器。

这是我记录屏幕和事件的代码：

import FirebaseAnalytics
import Foundation

public class AnalyticManager {
    public static func logScreen(_ name: String, className: String?) {
        Analytics.setScreenName(name, screenClass: className)
        Analytics.logEvent("open_screen", parameters: ["screenName": name])
    }
}

当我启动我的应用程序时，我遇到了这个崩溃：

当我使用 6.0 版的 Google 跟踪代码管理器时，应用程序不会崩溃，但我无法使用它，因为我需要 Firebase 的某些功能，这些功能需要与 Google 跟踪代码管理器 6.0 不兼容的最新版本 Firebase

我怎样才能摆脱那次崩溃？ 提前谢谢你。

好的，我找到了有相同问题的解决方案，从事件名称中删除“_”，所以我只是替换了这一行：

Analytics.logEvent("open_screen", parameters: ["screenName": name])

和：

Analytics.logEvent("openScreen", parameters: ["screenName": name])

它奏效了。
