为什么我的自定义字体在 Xamarin.iOS 中不起作用? [英] Why are my custom fonts not working in Xamarin.iOS?

问题描述

男孩，我被困住了.我想我已经在线查看了每个指南，但无法使其正常工作.以下是我已完成的步骤:

1. 我已将此自定义字体目录添加到我的 Xamarin.iOS 项目中在资源/字体下.
2. 我已将他们的构建操作全部设置为
   捆绑资源.
3. 我已为他们设置始终复制到构建中
   目录.
4. 我已将他们的名字添加到 Info.Plist 中，如下所示:

UIAppFonts<阵列><string>BentonSans-Regular.otf</string><string>BentonSans-Black.otf</string><string>BentonSans-Bold.otf</string><string>BentonSans-Book.otf</string><string>BentonSans-CompMediumRegular.otf</string><string>BentonSans-Medium.otf</string></阵列>

5. 我尝试像这样设置字体:

   button.Font = UIFont.FromName("BentonSansComp-Medium", 16);

请注意这样做，我的应用程序运行，但字体似乎没有任何效果.我曾尝试将 Fonts/ 放在 info.plist 中的字体前面，但这会导致代码中引用字体为空的异常.

我真的无法弄清楚我在这里遗漏了什么.字体似乎不适用.我使用 SushiHangover 的

这是我的 info.plist.(构建操作:BundleResource，复制到输出目录:始终复制)

UIAppFonts<阵列><string>Fonts/MyFonts/Winter.otf</string><string>Fonts/MyFonts/Goodest.ttf</string></阵列>

测试代码:

var lab1 = new UILabel(new RectangleF(0, 100, 300, 40));lab1.Text = "这是一些示例文本";lab1.Font = UIFont.FromName("Winter", 20f);this.Add(lab1);

Boy I'm stuck. I think I've looked at every guide online for this and cannot get it to work. Here are the steps I've done:

1. I've added this directory of custom fonts to my Xamarin.iOS project under Resources/Fonts.
2. I've set their buildactions all as
   BundledResources.
3. I've set for them to always copy to the build
   directory.
4. I've added their names to Info.Plist like so:

<key>UIAppFonts</key>
    <array>
      <string>BentonSans-Regular.otf</string>
      <string>BentonSans-Black.otf</string>
      <string>BentonSans-Bold.otf</string>
      <string>BentonSans-Book.otf</string>
      <string>BentonSans-CompMediumRegular.otf</string>
      <string>BentonSans-Medium.otf</string>
    </array>

5. I try setting the font like so:

   button.Font = UIFont.FromName("BentonSansComp-Medium", 16);

Please note doing it this way, my app runs, but the fonts don't seem to take any effect. I have tried putting Fonts/ in front of the fonts in info.plist, but this causes an exception where the referenced font is null in the code.

I really can't work out what I'm missing here. The fonts just don't seem to apply. I used SushiHangover's code to ensure that my fonts are registered:

2021-05-11 16:03:01.168473+0100 MyProject[54240:1851117]  * BentonSans Black
2021-05-11 16:03:01.169049+0100 MyProject[54240:1851117]  *-- BentonSans-Black
2021-05-11 16:03:01.169423+0100 MyProject[54240:1851117]  * BentonSans Bold
2021-05-11 16:03:01.169862+0100 MyProject[54240:1851117]  *-- BentonSans-Bold
2021-05-11 16:03:01.170201+0100 MyProject[54240:1851117]  * BentonSans Book
2021-05-11 16:03:01.170743+0100 MyProject[54240:1851117]  *-- BentonSans-Book
2021-05-11 16:03:01.171092+0100 MyProject[54240:1851117]  * BentonSans Comp Medium
2021-05-11 16:03:01.171826+0100 MyProject[54240:1851117]  *-- BentonSansComp-Medium
2021-05-11 16:03:01.172315+0100 MyProject[54240:1851117]  * BentonSans Medium
2021-05-11 16:03:01.173718+0100 MyProject[54240:1851117]  *-- BentonSans-Medium
2021-05-11 16:03:01.174237+0100 MyProject[54240:1851117]  * BentonSans Regular
2021-05-11 16:03:01.175211+0100 MyProject[54240:1851117]  *-- BentonSans-Regular

This showed me that I was getting the name wrong for BentonSansComp-Medium which did fix a runtime error earlier. But it didn't make the font apply.

解决方案

You used string "BentonSansComp-Medium" as the parameter of method "UIFont.FromName", but it doesn't exist in your plist.

I just followed the blog Using custom Fonts in Xamarin.iOS, and test with .ttf and .otf. Everything works fine.

Folder in Solution Explorer:

Here is my info.plist. (Build Action: BundleResource, Copy to Output Directory: Copy always)

<key>UIAppFonts</key>
<array>
  <string>Fonts/MyFonts/Winter.otf</string>
  <string>Fonts/MyFonts/Goodest.ttf</string>
</array>

test code:

var lab1 = new UILabel(new RectangleF(0, 100, 300, 40));
lab1.Text = "This is some sample text";
lab1.Font = UIFont.FromName("Winter", 20f);
this.Add(lab1);
