Xcode 4 Document Types and Exported UTIs

I have an other problem with Xcode 4. I really like the new IDE but there are a few things I didn't get to work yet. One thing is to register Document Types with Xcode 4. I tried it with the old way through the plist file, but it didn't work. (Means I couldn't open a file with my app) But I don't now how to set it up with the interface of Xcode 4.

My latest try looks like this: (Copied the entry made from Xcode in the info.plist)

我有一个关于Xcode4的其他问题。我真的很喜欢这个新的IDE，但也有几件让我无法工作的事情。其中一件事情是通过Xcode4注册文件类型。我试图通过老办法定义plist文件，但是它不能工作。（意味着我的应用程序不能打开一个文件），但是，我现在并不知道如何设置Xcode4的接口。

我的最新尝试看起来像这样：（复制在Info.plistXcode中的条目）

<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.plain-text</string>
        </array>
        <key>UTTypeDescription</key>
        <string>Configuration File</string>
        <key>UTTypeIdentifier</key>
        <string>com.myname.projec.iws</string>

    </dict>

</array>

and:

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>AnIcon-320</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>Config File</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.myname.projec.iws</string>
        </array>
    </dict>

</array>

This does not work. The file in Mail doesn't have the option to open with my app.

Does anyone have a working example with Xcode 4 or a tutorial how to do it. I don't have any further Idea how to get it work.

这是行不通的。邮件中附件没有打开我的应用程序的选项。

有谁有一个用于Xcode4工作良好的例子或怎么配置的教程。我是没有什么办法让它能正常工作了。

I think the role and the file extension are missing.
If you want to specify a file extension, you need to add UTTypeTagSpecification:

我觉得缺少的了Role和文件扩展名。
如果你想指定一个文件扩展名，你需要添加UTTypeTagSpecification KEY：

    <key>UTExportedTypeDeclarations</key>
<array>

    <dict>
        <key>UTTypeConformsTo</key>
        <array>
            <string>public.text</string>
        </array>
        <key>UTTypeDescription</key>
        <string>my document type</string>
        <key>UTTypeIdentifier</key>
        <string>com.mycompany.myfiletypename</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <array>
                <string>iws</string>
            </array>
        </dict>
    </dict>

For the role, you need to add CFBundleTypeRole:

关于Role，你需要添加CFBundleTypeRole KEY

<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeName</key>
        <string>My file</string>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>document-320.png</string>
            <string>document-64.png</string>
        </array>
        <key>LSHandlerRank</key>
        <string>Alternate</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.mycompany.myfiletypename</string>
        </array>
    </dict>
</array>
