如何实现Xamarin.Forms-iOS项目的共享扩展? [英] How to implement Share Extension to Xamarin.Forms - iOS project?

问题描述

我正在尝试对我的Xamarin.Forms应用程序实施共享扩展.我遵循了这些:

I am trying to implement a share extension to my Xamarin.Forms app. And I followed these:

https://docs.microsoft.com/tr-tr/xamarin/ios/platform/extensions

https://docs.microsoft. com/en-us/samples/xamarin/ios-samples/ios8-share/

https://github.com/xamarin/ios-samples/tree/master/ios8/Share

当我运行它时，上面的git repo可以正常工作.但是我需要为我的xamarin表单项目实现此功能. 因此，我执行了以下步骤:

And git repo above works when I run it. But I need to implement this for my xamarin forms project. So I did this steps:

1)我右键单击我的xamarin表单解决方案.选择添加后，新项目.我创建了"Share Extension(iOS)"项目. (我选择了.Net Framework 4.7.2)

1) I right clicked to my xamarin forms solution. After I select add, new project. And I created "Share Extension (iOS)" project. (I choosed .Net Framework 4.7.2)

2)使用ShareViewController创建一个共享扩展项目.我对此没有做任何更改.

2) A Share extension project is created with ShareViewController. I didn't do any change this.

3)我打开了新创建的ShareExtension项目的info.plist.并且我注意了束标识符.例如，我的xamarin项目的捆绑包标识符是"com.xamarin.test"，而我的共享扩展项目的捆绑包标识符是"com.xamarin.test.share-extension"

3) I opened info.plist of new created ShareExtension project. And I paid attention bundle identifier. For example my xamarin project's bundle identifier is "com.xamarin.test" and my share extension project's bundle identifier is "com.xamarin.test.share-extension"

4)我选择了主项目的MinimumOSVersion 10.0和共享扩展.

4) I selected MinimumOSVersion 10.0 of my main project and my share extension.

5)在我的项目中，NSExtension如下:

5) In my project,NSExtension is following:

> <key>NSExtension</key>
> <dict>
>   <key>NSExtensionAttributes</key>
>   <dict>
>       <key>NSExtensionActivationRule</key>
>       <dict>
>           <key>NSExtensionActivationSupportsFileWithMaxCount</key>
>           <integer>1</integer>
>           <key>NSExtensionActivationSupportsImageWithMaxCount</key>
>           <integer>1</integer>
>           <key>NSExtensionActivationSupportsMovieWithMaxCount</key>
>           <integer>1</integer>
>           <key>NSExtensionActivationSupportsText</key>
>           <false/>
>           <key>NSExtensionActivationSupportsWebURLWithMaxCount</key>
>           <integer>1</integer>
>       </dict>
>   </dict>
>   <key>NSExtensionMainStoryboard</key>
>   <string>MainInterface</string>
>   <key>NSExtensionPointIdentifier</key>
>   <string>com.apple.share-services</string>
> </dict>

6)在清理了整个解决方案并重建之后，我将引用共享扩展项目的dll添加到了xamarin ios项目中.之后，我运行该项目. (在iPhone 7 ios 12.0模拟器上)

6) After I cleaned whole solution and rebuilded, I added to reference shared extension project's dll to my xamarin ios project. After that I run the project. (on iphone 7 ios 12.0 simulator)

当我打开照片并单击共享照片时，我希望在共享菜单上看到我的应用程序.但这是行不通的.我想我错过了一步，但这是什么，我不知道.请有人帮我.

When I open photos and I click share for a photo, I expect to see my app on share menu. But it doesn't work. I guess I missed a step but what is this, I don't know. Somebody help me please.

推荐答案

您的问题在这里:

在我清理了整个解决方案并重建之后，我添加了参考 与我的xamarin ios项目共享扩展项目的dll.

After I cleaned whole solution and rebuilded, I added to reference shared extension project's dll to my xamarin ios project.

在文档中，当它说到 它必须维护对扩展项目的引用.

您应该右键单击xamarin ios project-> Add a reference-> Choose the shared extension project.你在做什么是相反的方式.

You should right click the xamarin ios project --> Add a reference --> Choose the shared extension project. What you are doing is a opposite way.

因此，请删除错误的引用并添加新的引用，清理并重建您的解决方案，然后再次运行.

So remove the wrong reference and add the new reference, clean and rebuild your solution, run again.
