如何在iOS中注册一个自定义文件类型 [英] How do I register a custom filetype in iOS

问题描述

我正在创建一个应用程序，我想让用户备份他们的文件（plist + m4a）。我压缩文件并将扩展名更改为自定义扩展名（专门针对我的应用程序，称为* .MyBackup）。然后，用户可以通过电子邮件或iTunes文件共享导出。

我已经阅读过有关CFBundleDocumentTypes但没有真正得到我对此的看法。 / p>

我目前停留的部分是如何将我的扩展名与我的应用关联。如果用户使用custom-zip文件发送自己的电子邮件，他应该可以使用我的应用程序打开它。

我该怎么做，什么是UTExportedTypeDeclarations？

解决方案

我希望如果我在我的项目info.plist的那部分转储没有太多的进一步的解释是没关系的。我认为这是非常不言自明的。

 < key> CFBundleDocumentTypes< / key>

I am currently creating a app in which i want to let the user backup their files (plist + m4a). I zip the files and change the extension to a custom one (specifically for my app, say "*.MyBackup"). The user can then either export via email or with iTunes file sharing.

I have already read about CFBundleDocumentTypes but didn't really get what I had to do with them.

The part where i am currently stuck at is how to associate my extension with my app. If the user sends himself an email with the "custom"-zip file he's supposed to be able to open it with my app.

How do I do this and what are "UTExportedTypeDeclarations"?

解决方案

I hope it's okay if I dump in that part of my projects info.plist without much further explanation. I think it's pretty much self-explanatory.

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>Icon-iPad-doc320.png</string>
            <string>Icon-iPad-doc.png</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>MyAppName File</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <!-- my app supports files with my custom extension (see UTExportedTypeDeclarations) -->
            <string>com.myurl.myapp.myextension</string>
            <!-- and csv files. -->
            <string>public.comma-separated-values-text</string>
        </array>
    </dict>
</array>



<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.data</string>
        </array>
        <key>UTTypeDescription</key>
        <string>MyAppName File</string>
        <key>UTTypeIdentifier</key>
        <string>com.myurl.myapp.myextension</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <string>myextension</string>
            <key>public.mime-type</key>
            <string>application/octet-stream</string>
