c# - 无法在 Xamarin.iOS 应用上启用 AppCenter.Crashes

Question

尝试在现有 Xamarin.iOS 应用程序上使用新的 AppCenter，我在 AppCenter.Crashes API 上遇到了一些问题。

我按照入门部分并在我的 AppDelegate.cs 中添加以下代码:

using Microsoft.AppCenter;
using Microsoft.AppCenter.Analytics;
using Microsoft.AppCenter.Crashes;

// ...
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
    //...
    // App Center
    AppCenter.Start("xxxxxxx-xxxx-xxxx-xxxx", typeof(Analytics), typeof(Crashes));

    return true;
}

我还安装了相应的 NuGet 包(这是我的 packages.config 中的相应行)

<package id="Microsoft.AppCenter" version="1.5.0" targetFramework="xamarinios10" />
<package id="Microsoft.AppCenter.Analytics" version="1.5.0" targetFramework="xamarinios10" />
<package id="Microsoft.AppCenter.Crashes" version="1.5.0" targetFramework="xamarinios10" />

请注意，如果我禁用 AppCenter.Crashes 模块:

AppCenter.Start("xxxxxxx-xxxx-xxxx-xxxx", typeof(Analytics));

一切都很好(我可以在应用中心后端看到分析)

但是启用 AppCenter.Crashes 模块后，我的应用程序崩溃并在控制台中显示以下消息:

最后的日志从 1.mscrasheslogbuffer 重复。至 59.mscrasheslogbuffer
请注意，我的应用程序加载遵循以下步骤:

加载带有图像的第一个 viewController，一个事件指示器
whitch 调用了一些 Rest API

在 API 调用之后，使用 NavBar

对另一个 ViewController 执行 segue

应用程序似乎在两步之间崩溃:我可以看到第一个屏幕和日志表明 http/api 的东西是好的。

请注意，我在模拟器和真实设备上具有相同的行为。

有任何想法吗 ？

编辑 1 : 使用 AppCenter.LogLevel = LogLevel.Verbose; 添加更多日志

Answer 1

我们这边也有同样的问题。

我们通过删除对 Microsoft.AppCenter 的 nuget 引用解决了这个问题。 .

换句话说，我们只保留了对 nuget 的引用

Microsoft.AppCenter.Analytics

Microsoft.AppCenter.Crashes

我们也在使用 1.5.0 版本。
