無法在 Xamarin.iOS 應用上啟用 AppCenter.Crashes

Question

嘗試在現有 Xamarin.iOS 應用程序上使用新 AppCenter，我在 AppCenter.Crashes API 上遇到了一些問題。

我遵循入門部分並在我的 AppDelegate.cs 中添加以下代碼：

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;
}

我還安裝了相應的 NuGet 包（這里是我的 packages.config 中的相應行）

<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" />

請注意，如果我禁用 AppCenter.Crashes 模塊：

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

一切都很好（我可以在應用中心后端看到分析）

但是啟用 AppCenter.Crashes 模塊后，我的應用程序崩潰並在控制台中顯示以下消息：

最后的日志從1.mscrasheslogbuffer重復到59.mscrasheslogbuffer

請注意，我的應用加載遵循以下步驟：

• 使用圖像加載第一個 viewController，一個調用一些 Rest API 的活動指示器
• API 調用后，使用 NavBar 執行到另一個 ViewController 的 segue

應用程序在兩步之間似乎崩潰了：我可以看到第一個屏幕和日志表明 http/api 內容正常。

請注意，我在模擬器和真實設備上的行為相同。

有什么想法嗎？

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

Answer 1

我們這邊也有同樣的問題。

我們通過刪除對Microsoft.AppCenter的 nuget 引用解決了這個問題。

換句話說，我們只保留了對

• Microsoft.AppCenter.Analytics
• Microsoft.AppCenter.Crashes

我們也在使用 1.5.0 版。
