当按下按钮时，应用程序崩溃，并显示与Firebase相关的错误

Question

在阅读所有这些内容之前，很长的帖子对不起，但是我想尽我所能地解释这种情况，因为我无法在线找到类似的错误。

大家好，我正在快速制作此应用，它的主屏幕带有“ loginButton”和“ signUp”

我在一个常规文件上制作了所有应用程序屏幕及其限制，然后安装了一些Pod。

pod 'Firebase'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'GoogleMaps'
pod 'GooglePlaces'

之后，我开始配置“注册”和“登录View”控制器以与Firebase通信。

注册很好，但是当我完成登录后，发生了一些事情。

每次我单击“ loginButton”时，我的应用都会由于没有明显的原因而崩溃（对我而言，我并没有那么快，而且仍然有很多无法识别的错误）

它给我的错误是“ [I-ACS036002]分析屏幕报告已启用。调用+ [FIRAnalytics setScreenName：setScreenClass：]设置屏幕名称或覆盖默认屏幕类名称。要禁用屏幕报告，请设置在Info.plist中将FirebaseScreenReportingEnabled标记为NO（布尔值）”

但是对我来说，这似乎不是问题所在，因为Firebase不会给我任何SignUp错误，这很奇怪，因为两个按钮的配置都相同。

我非常渴望获得帮助，因此如果您需要查看一些代码或其他内容，请告诉我，我将其发布。

我已经尝试删除从主屏幕到登录屏幕的按钮设置，并且错误仍在继续。

已经删除了我已经完成的LoginViewController，以查看它是否真的是我犯错的任何Firebase配置，但是错误仍然存​​在，并且在该视图控制器上我没有使用Firebase

并且显然已经做了Xcode在错误中建议的“要禁用屏幕报告，请将Info.plist中的FirebaseScreenReportingEnabled标志设置为NO（布尔值）”，并且该错误仍然存​​在。那个时候出现了一个不同的错误，该错误基本上只是告诉我我已将其禁用，并且该应用无法像这样运行。

我可以向您展示“注册”视图控制器代码，因为它与“登录”代码相同。

如果有谁能帮助我，我将非常感激，我现在​​需要该应用程序做的就是按预期工作，在用户输入凭据后将登录名重定向到主应用程序屏幕。< / p>
