.NET MAUI应用程序崩溃，因为它没有加载图像文件

Question

在我的.NET毛伊岛应用程序中，我将应用程序使用的图标从基于字体的图标更改为PNG文件，并将这些图像存储在Resources > Images文件夹中。

我成功地创建了一个软件包并将其上传到TestFlight，但是当我试图打开这个应用程序时，它会立即崩溃。在崩溃日志中，我发现造成崩溃的原因是该应用程序无法加载用于Flyout (即汉堡包菜单图标)的Flyout文件。

应用程序的另一个关键变化是，它现在是一个基于.NET 7的应用程序。

我以为发布过程会将应用程序使用的PNG图像添加到ipa包中，如果我将它们放在Resources > Images文件夹中的话。

你知道这里有什么问题吗？

Answer 1

我在Styles.xaml中设置了飞出图标，这就是问题所在--参见下面。

<Style TargetType="Shell" ApplyToDerivedTypes="True">
    <Setter Property="Shell.FlyoutIcon" Value="mymenuicon.png" />
</Style>

也许有一种方法可以在Styles.xaml中设置它，如果有人能在评论中告诉我如何设置它，我会很感激的。

解决我的问题的方法是简单地在AppShell中设置它，如下所示：

<Shell
   x:Class="MyApp.AppShell"
   FlyoutIcon="mymenuicon.png">
  ...
</Shell>
