问题描述

我做了一些研究，但似乎仍然没有运气

I did some research but seems still no luck

当我在我的info.plist中添加这些xml

when I added these xml in my info.plist

<key>UTImportedTypeDeclarations</key>
    <array>
        <dict>
            <key>UTTypeConformsTo</key>
            <array>
                <string>public.data</string>
            </array>
            <key>UTTypeIdentifier</key>
            <string>my.custom.uti</string>
            <key>UTTypeDescription</key>
            <string>PDF file</string>
        </dict>
    </array>
    <key>CFBundleDocumentTypes</key>
    <array>
        <dict>
            <key>LSItemContentTypes</key>
            <array>
                <string>public.data</string>
            </array>
            <key>CFBundleTypeIconFile</key>
            <string>Icon.png</string>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>

我发送3封电子邮件给自己。
1 - pdf文件。
2 - png文件。
3 - jpg和png文件。

and I send 3 email to myself. 1 - pdf file. 2 - png file. 3 - jpg and png file.

当我添加这些xmls时，我的应用程序可以在pdf和txt文件中显示，当点击打开...时
但我想要的是在图像中打开。
出了什么问题？
和我设置UITTypeConformsTo = public.data假设它是一般值。所以我的应用程序可以打开所有格式（至少pdf和图像），但似乎不。

when i added these xmls, my app can shows in pdf and txt file, when clicked "open with..." but what I want is open with in images. anything goes wrong?? and I set UITTypeConformsTo = public.data suppose that it is a general value. So that my app can open all the formats(at least pdf and images) , but seems it dont.

我也尝试将此答案中的xml复制到我的info.plist
https://stackoverflow.com/a/11609935/1061074 仍然没有运气

I also try to copy the xml in this answer to my info.plist https://stackoverflow.com/a/11609935/1061074 still no luck

推荐答案

它一切都取决于主机应用程序中共享按钮的实现方式。在iOS8中，实际上有两种不同的方法：（1）在Info.plist中使用CFBundleDocumentTypes，以及（2）应用程序扩展。一些应用程序，如GMail& AVR支持（1）和（2）。但Dropbox仅支持（2）。这就是为什么CFBundleDocumentTypes不再适用于Dropbox的原因。当然，事情可能会在以后发生变化。

It all depends on how "share" button in the host app is implemented. In iOS8, there are actually two different ways to do this: (1) using CFBundleDocumentTypes in Info.plist, and (2) Application Extension. Some apps such as GMail & AVR support both (1) & (2). But Dropbox supports (2) only. That's why CFBundleDocumentTypes does not work in Dropbox anymore. Of course, things may change later.
