那些遇到过的问题

为什么我的iOS应用程序没有出现在其他应用程序的"打开方式"对话框中？

31 file-handling uti ios launch-services

我正在尝试实现注册过程,该过程允许我的iOS应用程序显示在其他应用程序的"打开方式"列表中(如Apple的文档交互编程主题中所述).我希望我的应用程序能够处理来自任何提供标准音频文件格式(MP3,AIFF,WAV等)的应用程序的音频.

据我所知,我需要做的就是将CFBundleDocumentTypes关键字和相关的子数据添加到我的应用程序的Info.plist中.这是我放入的(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>

        <string>public.mp3</string>
        </array>
    </dict>

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(我在iPhone上测试,使用Dropbox中的MP3作为文件源.应用程序AudioMemos和Evernote都显示为Dropbox中的MP3文件,所以我知道支持的格式).有什么明显的东西我做错了,还是还有其他我需要实现的东西？

(注意:我没有UTExportedTypeDeclarations在我的Info.plist中设置一个项目,因为我理解这些只是自定义UTI所必需的.因为我使用的是系统UTI,我认为它不应该是必要的,但如果我有正确的请纠正我我错了.)

我添加了以下Exported Type UTI,但没有成功:
