i'm using InAppSettingsKit and i'm trying to include the key "ShortTitles" in my plist file per: https://developer.apple.com/library/ios/#documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSMultiValueSpecifier.html#//apple_ref/doc/uid/TP40007016-SW1
<dict>
<key>DefaultValue</key>
<string>0</string>
<key>Key</key>
<string>preferenceName</string>
<key>Title</key>
<string>MyPreferenceTitle</string>
<key>Type</key>
<string>PSMultiValueSpecifier</string>
<key>ShortTitles</key>
<array>
<string>None</string>
<string>Type1</string>
<string>Type2</string>
</array>
<key>Titles</key>
<array>
<string>None</string>
<string>Type1: description</string>
<string>Type2: description</string>
</array>
<key>Values</key>
<array>
<string>0</string>
<string>1</string>
<string>2</string>
</array>
</dict>
but it doesn't seem to be taking effect and only the Titles key is being used. am i missing something or is this key not allowed by IASK?
