【中文标题】为啥我的 iOS 应用没有显示在其他应用的“打开方式”对话框中？【英文标题】：Why is my iOS app not showing up in other apps' "Open in" dialog?为什么我的 iOS 应用没有显示在其他应用的“打开方式”对话框中？ 【发布时间】：2012-03-05 04:23:31 【问题描述】：

我正在尝试实现允许我的 ios 应用程序显示在其他应用程序的“打开方式”列表中的注册过程（如 Apple's Document Interaction Programming Topics 中所述）。我希望我的应用能够处理来自任何提供标准音频文件格式（MP3、AIFF、WAV 等）的应用的音频。

据我了解，我需要做的就是将带有相关子数据的 CFBundleDocumentTypes 键添加到我的应用程序的 Info.plist 中。这是我输入的（通过 Xcode 4 的文档类型编辑器）：

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>scrubbulator-icon</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>Audio</string>
        <key>LSHandlerRank</key>
        <string>Alternative</string>
        <key>LSItemContentTypes</key>
        <array>
        <string>public.mp3</string>
        </array>
    </dict>
</array>

添加此代码不会在应用程序的“打开方式”菜单中显示我的应用程序（我正在 iPhone 上进行测试，使用 Dropbox 中的 MP3 作为文件源。应用程序 AudioMemos 和 Evernote 都显示为 MP3 Dropbox 中的文件，所以我知道该格式受支持）。有什么明显的我做错了，还是有什么我需要实施的？

（注意：我没有在我的 Info.plist 中设置 UTExportedTypeDeclarations 项目，因为我知道这些仅对自定义 UTI 是必需的。因为我使用的是系统 UTI，所以我认为没有必要，但如果我错了，请纠正我。）

我添加了以下导出类型 UTI，但没有成功：

<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
        <string>kUTTypeMP3</string>
        </array>
        <key>UTTypeDescription</key>
        <string>Audio file</string>
        <key>UTTypeIdentifier</key>
        <string>kUTTypeMP3</string>
        <key>UTTypeTagSpecification</key>
        <dict>
        <key>public.filename-extension</key>

我并没有完全修复它，但是我从您上面的代码中复制了音频部分，它现在可以工作了！谢谢！（我已编辑您的代码以突出显示我复制的音频部分。）为了将来的参考，导出和导入类型的 UTI 不是必需的。非常感谢您这篇文章的出色工作......干得好嘿伙计们，它还在 IOS8 中工作吗？我只是将那些 xml 复制到我的 info.plist 中，只有 pdf 正在工作：/有什么想法吗？我在这里发布了一个新问题。***.com/questions/27419177/… 我在尝试上面的代码。它仅适用于 iMessage 和邮件附件文档文件。在 iPhone 的照片库中的照片共享中不显示应用程序。知道该怎么做吗？请帮助我@user577537【参考方案2】：

您应该使用Alternate 而不是Alternative

<key>LSHandlerRank</key>
<string>Alternate</string>
