I've defined a custom UTI for an iOS app and transferring files via AirDrop. Its all working as it should, except that on the receiving device the user is offered a choice of apps such as DropBox, Evernote, etc in addition to my app. I'd like to prevent this, so the user is only shown my app as the choice. Is this possible? 

In my info.plist I have:

```
<key>CFBundleDocumentTypes</key>
<array>
    <dict>
        <key>CFBundleTypeIconFiles</key>
        <array>
            <string>Icon.png</string>
        </array>
        <key>CFBundleTypeName</key>
        <string>My Text</string>
        <key>CFBundleTypeRole</key>
        <string>Viewer</string>
        <key>LSHandlerRank</key>
        <string>Owner</string>
        <key>LSItemContentTypes</key>
        <array>
            <string>com.me.text</string>
        </array>
    </dict>
</array>
<key>UTExportedTypeDeclarations</key>
<array>
    <dict>
        <key>UTTypeDescription</key>
        <string>My Text</string>
        <key>UTTypeIdentifier</key>
        <string>com.me.text</string>
        <key>UTTypeTagSpecification</key>
        <dict>
            <key>public.filename-extension</key>
            <string>per</string>
        </dict>
    </dict>
</array>

```

What am I doing wrong?
