Question

我在我的应用程序中将Google跟踪代码管理器与Firebase一起使用。

这是我的代码，用于记录屏幕和事件：

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])
    }
}

启动我的应用程序时，出现此崩溃：

当我使用Google跟踪代码管理器6.0版时，该应用程序不会崩溃，但无法使用，原因是我需要Firebase的某些功能，这些功能要求最新版本的Firebase与Google跟踪代码管理器6.0不兼容

如何摆脱崩溃？谢谢你。

好吧，我找到了解决相同问题的解决方案，从事件名称中删除“ _”，所以我只替换了这一行：

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

具有：

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

成功了。

带有Firebase的Google跟踪代码管理器导致iOS崩溃
