Hi there, I'd like to create and expose an Audio Unit Extension for iOS, but there are no parameters that a user can set. Is it possible to expose an Audio Unit Extension without a storyboard? If I leave the storyboard-entry empty in the plist, the extension will crash ...
Audio Extension without UI
You have to set NSExtensionPrincipalClass entry in the plist instead of NSExtensionViewController or NSExtensionMainStoryboard.
Make sure you have set the NSExtensionPointIdentifier to com.apple.AudioUnit - this is the Identifier for an AU without GUI.
For more informations see AUAudioUnitImplementation.h in the AudioUnit Framework ;-)
Cheers
